FEBRUARY __, 1998

6,000,000 Securities


AES TRUST II
$2.75 Term Convertible Securities, Series B ("TECONS SM")

(Liquidation  amount $50 per security) fully and  unconditionally  guaranteed as
set forth herein by and convertible into Common Stock of,



[AES LOGO]            THE AES CORPORATION


     The $2.75 Term Convertible Securities, Series B (the "TECONS" or "Preferred
Securities"),  liquidation  amount $50 per  security,  offered for resale hereby
were issued by AES Trust II, a statutory business trust formed under the laws of
the State of Delaware  ("AES  Trust" or the  "Trust").  These  TECONS  represent
preferred undivided  beneficial interests in the assets of the Trust. The TECONS
were  issued  and sold  (the  "Original  Offering")  on  October  29,  1997 (the
"Original   Offering  Date")  to  certain   initial   purchasers  (the  "Initial
Purchasers")  and  were   simultaneously  sold  by  the  Initial  Purchasers  in
transactions exempt from the registration  requirements of the Securities Act of
1933,  as  amended  (the  "Securities  Act"),  in the  United  States to persons
reasonably  believed by the Initial  Purchasers  to be  qualified  institutional
buyers  ("Qualified  Institutional  Buyers")  as  defined in Rule 144A under the
Securities  Act  or  institutional  accredited  investors  as  defined  in  Rule
501(a)(1),  (2), (3) or (7) under the Securities Act ("Institutional  Accredited
Investors")  and  outside  the United  States to  non-U.S.  persons in  offshore
transactions in reliance on Regulation S under the Securities Act.

     The AES Corporation, a Delaware corporation ("AES" or the "Company"),  owns
directly or indirectly all the common securities (the "Common Securities" or the
"Trust  Common   Securities,"   and  together   with  the  TECONS,   the  "Trust
Securities"),  representing  undivided beneficial interests in the assets of AES
Trust. AES Trust exists for the sole purpose of issuing the TECONS and the Trust
Common   Securities   and  investing  the  proceeds   thereof  in  5.50%  Junior
Subordinated   Convertible   Debentures  due  2012  (the  "Junior   Subordinated
Debentures")  of AES in an aggregate  principal  amount  equal to the  aggregate
liquidation amount of the Trust Securities.  The Junior Subordinated  Debentures
and the  TECONS in  respect  of which this  Prospectus  is being  delivered  are
referred  to  herein  as  the  "Offered  Securities."  The  Junior  Subordinated
Debentures are unsecured  obligations of AES  subordinate and junior in right of
payment  to  certain  other  indebtedness  of AES as  described  herein.  Upon a
Declaration Event of Default (as defined herein), the holders of the TECONS will
have a preference  over the holders of the Trust Common  Securities with respect
to payment in respect of  Distributions  (as defined  herein) and payments  upon
redemption, liquidation and otherwise.

     The  TECONS  (and the Junior  Subordinated  Debentures  and the  securities
issuable upon conversion) in respect of which this Prospectus is being delivered
(the  "Offered  Securities")  may be  offered  and sold from time to time by the
holders  thereof  named  herein or in a  supplement  hereto  (collectively,  the
"Selling  Holders")  pursuant to this  Prospectus as  supplemented.  The Offered
Securities  may be sold by the  Selling  Holders  from time to time  directly to
purchasers  or  through   agents,   underwriters   or  dealers.   See  "Plan  of
Distribution" and "Selling  Holders." If required,  the names of any such agents
or  underwriters  involved  in  the  sale  of the  Offered  Securities  and  the
applicable  agent's   commission,   dealer's  purchase  price  or  underwriter's
discount,  if any,  will be set  forth  in an  accompanying  supplement  to this
Prospectus (the "Prospectus  Supplement").  The Selling Holders will receive all
of the net  proceeds  from the sale of the Offered  Securities  and will pay all
underwriting  discounts and selling commissions,  if any, applicable to any such
sale. The Company is responsible  for payment of all other expenses  incident to
the  offer and sale of the  Offered  Securities.  The  Selling  Holders  and any
broker-dealers,  agents or underwriters which participate in the distribution of
the Offered Securities may be deemed to be "underwriters"  within the meaning of
the Securities  Act, and any  commission  received by them and any profit on the
resale  of  the  Offered  Securities  purchased  by  them  may be  deemed  to be
underwriting  commissions or discounts  under the  Securities  Act. See "Plan of
Distribution" for a description of indemnification arrangements.

     Holders of the TECONS are entitled to receive cumulative cash distributions
at an annual  rate of $2.75 per  TECONS,  accruing  from  October  29,  1997 and
payable  quarterly  in  arrears  on the  last  day  of  each  calendar  quarter,
commencing  on  December  31,  1997.  The term  "Distributions"  as used  herein
includes  such  cash  distributions  and any  interest  payable  thereon  unless
otherwise  stated.  The Distribution rate and the Distribution and other payment
dates for the TECONS will  correspond  to the interest rate and the interest and
other payment dates on the Junior Subordinated Debentures deposited in the Trust
as trust

     SEE  "SPECIAL NOTE REGARDING FORWARD LOOKING STATEMENTS" AND "RISK FACTORS"
FOR  A  DESCRIPTION  OF  CERTAIN  RISK  FACTORS  THAT  SHOULD  BE  CONSIDERED BY
PROSPECTIVE INVESTORS.

     THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURI-
        TIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
          NOR HAS THE SECURITIES EXCHANGE COMMISSION OR ANY STATE SE-
              CURITIES COMMISSION PASSED UPON THE ACCURACY OR ADE-
              QUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE
                        CONTRARY IS A CRIMINAL OFFENSE.

Information   contained  herein  is  subject  to  completion  or  amendment.   A
registration  statement  relating  to these  securities  has been filed with the
Securities  and Exchange  Commission.  These  securities may not be sold nor may
offers to buy be accepted prior to the time the registration  statement  becomes
effective.  This  prospectus  shall  not  constitute  an  offer  to  sell or the
solicitation of an offer to buy nor shall there be any sale of these  securities
in any State in which such offer,  solicitation  or sale would be unlawful prior
to registration or qualification under the securities laws of any such State.

assets.  If  principal  or  interest  is not  paid  on the  Junior  Subordinated
Debentures,  including  as a result of the  Company's  election  to  extend  the
interest  payment  period on the Junior  Subordinated  Debentures  as  described
below,  the Trust will not make  payments  on the Trust  Securities.  The Junior
Subordinated  Debentures  provide  that,  so long as the Company shall not be in
default in the payment of interest on the Junior  Subordinated  Debentures,  the
Company  shall  have the  right to defer  payments  of  interest  on the  Junior
Subordinated  Debentures by extending the interest  payment  period from time to
time for a period not exceeding 20 consecutive quarterly interest periods (each,
an "Extension Period"). No interest shall be due and payable during an Extension
Period and, as a consequence, distributions on the Trust Securities will also be
deferred,  but at the end of such  Extension  Period the  Company  shall pay all
interest then accrued and unpaid on the Junior Subordinated Debentures, together
with  interest  thereon  at the  rate  specified  for  the  Junior  Subordinated
Debentures  to the extent  permitted by  applicable  law,  compounded  quarterly
("Compounded  Interest").  All  references  herein  to  interest  shall  include
Compounded  Interest unless otherwise stated.  There could be multiple Extension
Periods  of  varying  lengths  throughout  the term of the  Junior  Subordinated
Debentures, not to exceed 20 consecutive quarters; provided, that no such period
may extend  beyond the stated  maturity of the Junior  Subordinated  Debentures.
During any such Extension  Period,  the Company may not declare or pay dividends
on, or redeem,  purchase,  acquire or make a distribution or liquidation payment
with respect to, any of its common stock or preferred  stock;  provided that the
foregoing  will not  apply to any stock  dividends  paid by the  Company  in its
common  stock,  par value $.01 per share (the "AES Common  Stock" or the "Common
Stock"). See "Description of the Junior Subordinated Debentures -- Interest" and
"-- Option to Extend  Interest  Payment  Period" and "Risk  Factors -- Option to
Extend Interest Payment Period; Tax Impact of Extension."

     The payment of  Distributions  out of moneys held by AES Trust and payments
on liquidation  of AES Trust and the  redemption of TECONS,  as set forth below,
are guaranteed by the Company on a subordinated  basis (the  "Guarantee") as and
to the  extent  described  herein.  The  Guarantee  is a full and  unconditional
guarantee  from the time of  issuance of the TECONS,  but the  Guarantee  covers
Distributions  and other  payments  on the TECONS only if and to the extent that
AES Trust has funds  available  therefor,  which will not be the case unless the
Company  has made a payment  to the  Property  Trustee  (as  defined  herein) of
interest or principal  on the Junior  Subordinated  Debentures  deposited in the
Trust as trust assets.  The  obligations  of the Company under the Guarantee are
subordinate  and  junior in right of  payment  to all other  liabilities  of the
Company,  including Junior Subordinated Debentures,  and will rank pari passu in
right of payment with the most senior preferred stock issued, from time to time,
if any, by AES. The  obligations  of the Company  under the Junior  Subordinated
Debentures  are  subordinate  and junior in right of payment to all  present and
future Senior and Subordinated Debt (as defined herein).  Because the Company is
a  holding  company,  the  Junior  Subordinated  Debentures  (and the  Company's
obligations  under  the  Guarantee)  are also  effectively  subordinated  to all
existing and future  liabilities,  including  trade  payables,  of the Company's
subsidiaries,  except  to the  extent  that the  Company  is a  creditor  of the
subsidiaries and recognized as such.

     Each TECONS is convertible in the manner  described herein at the option of
the  holder,  at any time prior to the  Conversion  Expiration  Date (as defined
herein),  into AES  Common  Stock at the  initial  rate of 0.8914  shares of AES
Common  Stock for each  TECONS  (equivalent  to an initial  conversion  price of
$56.09  per  share of AES  Common  Stock),  subject  to  adjustment  in  certain
circumstances.  See  "Description  of the TECONS -- Conversion  Rights." The AES
Common Stock is listed on the NYSE under the symbol "AES." On February 10, 1998,
the reported last sale price of the AES Common Stock on the NYSE  Composite Tape
was $41.25 per share.

     The Junior Subordinated  Debentures are redeemable by the Company (in whole
or in part)  from time to time,  on or after  September  30,  2000 at the prices
specified herein or at any time in certain  circumstances upon the occurrence of
a Tax Event (as defined  herein) at 100% of the  principal  amount  thereof plus
accrued  and  unpaid  interest  thereon to the date  fixed for  redemption  (the
"Redemption Price"). If the Company redeems Junior Subordinated Debentures,  the
Trust must redeem, at the Redemption Price, Trust Securities having an aggregate
liquidation  amount  equal  to the  aggregate  principal  amount  of the  Junior
Subordinated Debentures so redeemed. See "Description of the TECONS -- Mandatory
Redemption."   The  TECONS  will  be  redeemed   upon  maturity  of  the  Junior
Subordinated Debentures.  The Junior Subordinated Debentures mature on September
30,  2012.  In  addition,  upon the  occurrence  of a Special  Event (as defined
herein) arising from a change in law or a change in legal interpretation, unless
the Junior  Subordinated  Debentures  are redeemed in the limited  circumstances
described  below,  the Trust shall be dissolved  with the result that the Junior
Subordinated  Debentures  will  be  distributed  to the  holders  of  the  Trust
Securities,  on a pro rata basis, in lieu of any cash distribution.  In the case
of a Special  Event  that is a Tax  Event,  the  Company  will have the right in
certain circumstances to redeem the Junior Subordinated Debentures,  which would
result in the redemption by the Trust of the Trust Securities in the same amount
on a pro rata basis.  See "Description of the TECONS -- Special Event Redemption
or Distribution" and "Description of the Junior Subordinated Debentures."

     In the event of the  voluntary or  involuntary  dissolution,  winding up or
termination of the Trust, the holders of the TECONS will be entitled to receive,
for  each  TECONS,  a  liquidation   amount  of  $50  plus  accrued  and  unpaid
distributions  thereon  (including  interest  thereon)  to the date of  payment,
unless in connection with such dissolution,  the Junior Subordinated  Debentures
are distributed to the holders of the TECONS.  See "Description of the TECONS --
Liquidation Distribution Upon Dissolution."

                               PROSPECTUS SUMMARY

     The  following  summary is qualified in its entirety by, and should be read
in connection  with, the more detailed  information and  consolidated  financial
statements and the notes thereto  included and incorporated by reference in this
Prospectus.  References  herein  to  "AES"  or the  "Company"  include  The  AES
Corporation  and its  subsidiaries  and affiliates  unless the context  requires
otherwise and references herein to "MW" are to megawatts.


                                  THE COMPANY

     AES is a  global  power  company  committed  to  supplying  electricity  to
customers  world-wide in a socially  responsible way. The Company was one of the
original  entrants  in the  independent  power  market  and  today is one of the
world's  largest  global  power  companies,  based on net  equity  ownership  of
generating  capacity (in  megawatts)  in operation  or under  construction.  AES
markets  power  principally  from  electricity  generating  facilities  that  it
develops, acquires, owns and operates.

     Over the last five years, the Company has experienced  significant  growth.
This growth has resulted  primarily from the development and construction of new
plants  ("greenfield  development")  and also from the  acquisition  of existing
generating  plants  and  distribution   companies,   through  competitively  bid
privatization   initiatives   outside  of  the  United   States  or   negotiated
acquisitions.  Since 1992, the Company's total generating  capacity in megawatts
has  grown  from  1,829 MW to 16,938 MW (an  increase  of 826%),  with the total
,number of plants in operation  increasing from eight to 73.  Additionally,  the
Company's  total revenues have increased at a compound annual growth rate of 20%
from  $401  million  in 1992 to $835  million  in 1996,  while  net  income  has
increased  at a  compound  annual  growth  rate of 22% from $56  million to $125
million and  Consolidated  EBITDA (as defined  herein)  has  increased  from $45
million to $189 million over the same period.

     AES  operates  and owns  (entirely or in part),  through  subsidiaries  and
affiliates,  power  plants in ten  countries  with a capacity  of  approximately
16,938 MW (including  4,000 MW  attributable  to Ekibastuz which currently has a
capacity  factor  of up to  approximately  20%).  AES  is  also  constructing  9
additional  power  plants in seven  countries  with a capacity of  approximately
4,921 MW.  The  Company's  total  ownership  in plants  in  operation  and under
construction aggregates  approximately 21,859 MW and its net equity ownership in
such plants is approximately  11,379 MW. In addition,  AES has numerous projects
in advanced stages of development, including seven projects with design capacity
of  approximately  3,398 MW that  have  executed  or been  awarded  power  sales
agreements.

     The  Company  is also  engaged  (entirely  or in  part) in  electric  power
distribution   businesses  in  Latin  America  through  its   subsidiaries   and
affiliates.  These  subsidiaries and affiliates  (including  CCODEE) (as defined
herein) serve approximately eight million commercial, industrial and residential
customers using approximately 63,000 gigawatt hours per year.

     As a result  of the  Company's  significant  growth in  recent  years,  the
Company's  operations have become more diverse with regard to both geography and
fuel  source  and it has  reduced  its  dependence  upon any  single  project or
customer.  During 1996, four of the Company's projects individually  contributed
more than 10% of the Company's  total  revenues;  Shady Point which  represented
approximately 20%, San Nicolas which represented approximately 16%, Thames which
represented  approximately 16% and Barbers Point which represented approximately
15%.

     The Company, a corporation organized under the laws of Delaware, was formed
in 1981.  The  principal  office of the  Company  is  located at 1001 North 19th
Street, Suite 2000, Arlington, Virginia 22209, and its telephone number is (703)
522-1315.

                                    OUTLOOK

     The  global  trend  of  electricity   market   restructuring   has  created
significant new business opportunities for companies like AES. Both domestic and
international  electricity  markets are being  restructured and there is a trend
away from government-owned  electricity systems toward deregulated,  competitive
market  structures.  Many countries have rewritten their laws and regulations to
allow  foreign  investment  and private  ownership  of  electricity  generation,
transmission or distribution  systems. Some countries have or are in the process
of  "privatizing"  their  electricity  systems  by  selling  all or part of such
systems to private  investors.  With 68 of its operating plants and distribution
companies  having been acquired or commenced  commercial  operations since 1992,
AES has  been an  active  participant  in both the  international  privatization
process and the development  process.  The Company is currently pursuing over 90
projects  including  acquisitions,  the  expansion  of  existing  plants and new
projects.

     AES  believes  that  there  is  significant  demand  for  both new and more
efficiently  operated  electric  generating  capacity in many regions around the
world.  In an effort to further grow and diversify  the  Company's  portfolio of
electric generating plants, AES is pursuing,  through its integrated  divisions,
additional greenfield  developments and acquisitions in many countries.  Several
of these  acquisitions,  if  consummated,  would  require  the Company to obtain
substantial additional financing, in the form of both debt and equity financing,
in the short term.


                                    STRATEGY

     The Company's  strategy in helping meet the world's need for electricity is
to participate in competitive power markets as they develop either by greenfield
development or by acquiring and operating  existing  facilities or  distribution
systems in these markets.  The Company generally  operates  electric  generating
facilities  that utilize  natural gas, coal,  oil, hydro power,  or combinations
thereof.   In  addition,   the  Company   participates  in  the  electric  power
distribution and retail supply businesses in certain limited instances, and will
continue to review opportunities in such markets in the future.

     Other elements of the Company's strategy include:


     o Supplying  energy to customers at the lowest cost  possible,  taking into
       account factors such as reliability and environmental performance;

     o Constructing or acquiring  projects of a relatively large size (generally
       larger than 100 MW);

     o When  available,  entering  into  power  sales  contracts  with  electric
       utilities or other customers with significant credit strength; and

     o Participating  in electric power  distribution  and retail supply markets
       that grant concessions with long-term pricing arrangements.


     The Company also strives for  operating  excellence as a key element of its
strategy, which it believes it accomplishes by minimizing  organizational layers
and maximizing company-wide participation in decision-making.  AES has attempted
to create an  operating  environment  that  results in safe,  clean and reliable
electricity generation. Because of this emphasis, the Company prefers to operate
all facilities which it develops or acquires; however, there can be no assurance
that the Company will have operating control of all of its facilities.

     Where  possible,  AES attempts to sell  electricity  under  long-term power
sales  contracts.  The Company  attempts,  whenever  possible,  to structure the
revenue  provisions of such power sales  contracts such that changes in the cost
components of a facility  (primarily fuel costs)  correspond,  as effectively as
possible, to changes in the revenue components of the contract. The Company also
attempts to provide fuel for its  operating  plants  generally  under  long-term
supply agreements,  either through  contractual  arrangements with third parties
or, in some instances, through acquisition of a dependable source of fuel. 


                                        6
<PAGE>


     As electricity  markets become more  competitive,  it may be more difficult
for AES (and other power  generation  companies) to obtain long-term power sales
contracts.  In markets where  long-term  contracts are not  available,  AES will
pursue  methods to hedge  costs and  revenues  to provide as much  assurance  as
possible of a project's profitability.  In these situations, AES might choose to
purchase a project with a partial hedge or with no hedge, with the strategy that
its  diverse  portfolio  of  projects  provides  some  hedge  to  the  increased
volatility of the project's earnings and cash flow. Additionally, AES may choose
not to participate in these markets. 

     The Company  attempts to finance each domestic and foreign plant  primarily
under loan  agreements  and  related  documents  which,  except as noted  below,
require the loans to be repaid  solely from the  project's  revenues and provide
that the repayment of the loans (and interest  thereon) is secured solely by the
capital  stock,  physical  assets,  contracts  and/or  cash  flow of that  plant
subsidiary  or  affiliate.  This type of financing  is generally  referred to as
"project financing." The lenders under these project financing structures cannot
look to AES or its other projects for repayment,  unless such entity  explicitly
agrees to undertake  liability.  AES has explicitly  agreed to undertake certain
limited  obligations  and contingent  liabilities,  most of which by their terms
will only be  effective  or will be  terminated  upon the  occurrence  of future
events. In certain  circumstances,  the Company may incur  indebtedness which is
recourse to the Company or to more than one project.


                              RECENT DEVELOPMENTS

Recent Acquisitions

     On January 26,  1998,  the Company  announced  that it was  selected by the
Government of Bangladesh Ministry of Energy and Mineral Resources as the winning
bidder to build,  own and operate a 360 MW (net) gas-fired  combined cycle power
plant at a site near  Dhaka,  Bangladesh  ("Haripur").  Haripur is  expected  to
commence commercial operations in the year 2000, and electricity will be sold to
the  Bangladesh  Power  Development  Board  under the  terms of a 22-year  power
purchase  agreement  which is expected to be signed  following the formal award.
Titus Gas Transmission and  Distribution  Company,  a subsidiary of Petrobangla,
will supply  natural gas to the facility from a nearby  pipeline for the term of
the power purchase agreement.

     On January 21, 1998, the Company announced that it won a bid to acquire for
$109 million the  outstanding  shares  (79.78%) of Compania de Luz  Electrica de
Santa Ana (CLESA),  an  electrical  distribution  company in El Salvador.  These
shares will be purchased from Comision  Ejecutiva  Hidroelectrica  del Rio Lempa
(CEL), a government-owned utility company. Energia Global International, Ltd., a
Bermuda company,  with activities in Central America,  may purchase up to 20% of
CLESA from AES.

     CLESA serves  188,000  customers and borders  Guatemala and Honduras to the
north, with access to the Pacific Ocean. Three other  distribution  companies in
El Salvador were sold in the same auction to two other private companies.
Closing is expected to occur in mid-February 1998.

     In November 1997, the Company  announced that it won a bid to acquire three
natural gas-fired,  electric generating stations from Southern California Edison
for  approximately  $781  million.  The  facilities  were  auctioned  as part of
Edison's divestiture of all of its gas-fired generating  facilities prior to the
restructuring of California's electricity industry.

     The three  plants,  all  located  on the  southern  California  coast,  are
Alamitos (2083 MW),  Redondo Beach (1310 MW) and Huntington Beach (563 MW). Each
of the plants has been designated a "must-run  facility"  because station output
is critical to maintaining  the  reliability  of electric  supply in the region.
Consequently,  they  initially  will operate in part under  agreements  with the
Independent System Operator being established through electricity restructuring.
Pursuant to California's electricity restructuring law, Edison will remain under
contract to operate and maintain the facilities for two years. 


                                       7
<PAGE>


     Completion  of the  acquisition  is  subject  to a  number  of  conditions,
including the receipt of California  Public  Utilities  Commission  approval and
successful implementation of the new California electric spot market, called the
Power Exchange.

     On October 21, 1997, a subsidiary of AES was the winning  bidder to acquire
approximately 90% of the common shares of Companhia Centro-Oeste de Distribuicao
de Energia Eletrica ("CCODEE"), the distribution company serving the central and
western  sections  of the  State of Rio  Grande  do Sul in  Brazil,  for a total
purchase price of approximately $1.37 billion. The acquisition closed on October
27, 1997, at which time the Company  financed the payment of the purchase  price
with the proceeds of (i) $220 million of revolving  credit  borrowings under its
$425 million  revolving credit facility (the "Revolver") (the commitments  under
which had been  temporarily  increased from $425 million to $600 million),  (ii)
$550 million of short term loans under a bridge loan  facility (the "CEEE Bridge
Loan") to be provided by affiliates of J.P. Morgan Securities,  Inc., Donaldson,
Lufkin & Jenrette  Securities  Corporation,  Salomon  Brothers Inc and Unterberg
Harris  (each of which was an Initial  Purchaser  in one or both of the  Initial
Offerings  referred to below) and (iii) $600 million of  non-recourse  financing
under a $680 million  facility to be provided by BankBoston  and ANZ  Investment
Bank as  co-arrangers  (the "CEEE  Non-recourse  Financing").  AES purchased the
shares of CCODEE from the State of Rio Grande do Sul in a partial  privatization
of Companhia  Estadual de Energia Eletrica  ("CEEE"),  the integrated utility of
Rio Grande do Sul. All of the remaining shares of CCODEE may be purchased by its
employees.   CCODEE  currently  serves   approximately   800,000   customers  or
approximately 31.3% of the population of the State of Rio Grande do Sul on sales
of 5,772 gigawatt hours. The foregoing  transaction and the financing  described
therein  and  below are  referred  to  herein  as the  "CEEE  Acquisition".  The
Borrowings  under the Revolver and the CEEE Bridge Loan were refinanced with the
proceeds of the Initial Offerings. See "Use of Proceeds."

     Also in October  1997, a joint venture named Tau Power that is 85% owned by
AES and 15% owned by  Israel-based  Suntree Power  completed the acquisition and
takeover of two hydro-electric stations ("GES") and four combined heat and power
stations  ("TETS")  in the  province  of East  Kazakhstan.  The  total  electric
capacity of the stations  included in the agreement is 1,384 MW, with additional
thermal capacity of over 1,000 MW electric  equivalent.  The transaction expands
AES's current global portfolio of electric generating facilities,  which already
includes the 4,000 MW  coal-fired  Ekibastuz  power station in  Kazakhstan.  The
power stations included in the agreement signed are: the 332 MW  Ust-Kamenogorsk
GES,  the 702 MW  Shulbinsk  GES,  the 240 MW  Ust-Kamenogorsk  TETS,  the 50 MW
Leninogorsk  TETS,  the 50 MW Sogrinsk  TETS and the 10 MW  Semipalatinsk  TETS.
Included in the  transaction,  AES obtained  ownership and control of the retail
sales department of the former utility and will assume the existing power supply
contracts  with the 50  largest  customers  in East  Kazakhstan,  including  the
distribution  companies.  Tau Power paid $20.7 million for the concession on the
GES, with an additional  payment of $2.5 million for the shares of the TETS. The
Company  will also repay back wages of  approximately  $4 million to the workers
during the first year of  operation  and provide for working  capital to finance
the delivery of much needed coal prior to winter and complete winter preparation
plans.

     In June 1997,  AES together with The Southern  Company and The  Opportunity
Fund,  a  Brazilian  investment  fund,  (collectively,  the  "AES  Consortium"),
acquired 14.41% of Companhia Energetica de Minas Gerais ("CEMIG"), an integrated
electric  utility  serving  the  State of Minas  Gerais in  Brazil,  for a total
purchase price of  approximately  $1.056 billion,  $654 million of the financing
for which was in the form of non-recourse  financing  provided by Banco Nacional
de Desenvolvimento  Economico e Social ("BNDES").  AES's portion of the purchase
price was approximately $364 million after  consideration of the BNDES facility.
The shares of CEMIG,  which represent  approximately 33% of the voting interest,
have been purchased from the State of Minas Gerais in a partial privatization of
CEMIG.  Initially,  AES and The Opportunity Fund had a 90.6% and a 9.4% economic
interest in the AES Consortium, respectively. Subsequently, the Southern Company
exercised its option to purchase a 25% interest in the AES Consortium  from AES.
Pursuant to a shareholders agreement between the AES Consortium and the State of
Minas Gerais, 


                                        8
<PAGE>

AES will have significant  operating  influence,  including the right to appoint
the chief operating  officer of CEMIG, and will otherwise share control of CEMIG
with the State of Minas Gerais.  CEMIG owns approximately 5,000 MW of generating
plants and serves approximately 4 million customers.  The foregoing  transaction
and the financing  therefor described below are referred to herein as the "CEMIG
Acquisition".

     In June 1997, AES completed its acquisition of the international  assets of
Destec  Energy,  Inc.  ("Destec"),  a large  independent  energy  producer  with
headquarters in Houston,  Texas, at a total price to AES of  approximately  $439
million.  Destec's  international  assets  acquired  by  AES  include  ownership
interests in the  following  five  electric  generating  plants (with  ownership
percentages  in  parentheses):  (i) a 110 MW gas-fired  combined  cycle plant in
Kingston,  Canada  (50%);  (ii) a 405  MW  gas-fired  combined  cycle  plant  in
Terneuzen,  Netherlands  (50%);  (iii) a 140 MW gas-fired  simple cycle plant in
Cornwall,  England (100%);  (iv) a 235 MW oil-fired  simple cycle plant in Santo
Domingo,  Dominican  Republic  (99%);  and  (v)  a  1,600  MW  coal-fired  plant
("Hazelwood") in Victoria,  Australia (20%). Each of such plants is currently in
operation,  except for the plant in Terneuzen which is under  construction.  The
acquisition  by AES of  Destec's  international  assets also  includes  Destec's
non-U.S.  developmental stage power projects,  including projects in Taiwan, the
Philippines,   Australia  and  Argentina.  The  foregoing  transaction  and  the
financing  therefor  described  below are  referred  to  herein  as the  "Destec
Acquisition".

     In May  1997,  a  subsidiary  of AES,  and its  partner,  Community  Energy
Alternatives  ("CEA"),  acquired an aggregate  of 90% (AES  acquired 60% and CEA
acquired  30%) of two  distribution  companies  of Empresa  Social de Energia de
Buenos Aires S.A.  ("ESEBA")  serving certain portions of the Province of Buenos
Aires,  Argentina for an aggregate purchase price of $565 million. AES's portion
of the purchase price after consideration of non-recourse debt was $244 million.
The  remaining  10% is  owned  by the  employees  of each  of the  two  acquired
companies.  The  foregoing  transaction  is  referred  to herein  as the  "ESEBA
Acquisition".

     AES funded its  acquisition  of Destec  through cash on hand and borrowings
under the  Revolver.  The net  proceeds of  approximately  $387 million from the
Company's  issuance and sale of its common stock,  par value $.01 per share (the
"AES Common Stock"), and $2.6875 Term Convertible Securities,  Series A ("Series
A TECONS") in March 1997 was  temporarily  applied to repay amounts  outstanding
under the Revolver.  AES financed its  acquisitions  of CEMIG and ESEBA through:
(i) $450 million in non-recourse  bridge financing,  comprised of a $250 million
bridge  loan  (the  "CEMIG  Bridge")  to  AES  CEMIG  Funding   Corporation,   a
wholly-owned  subsidiary  of AES,  and a $200  million  bridge  loan (the "ESEBA
Bridge") to AESEBA Funding Corporation, a wholly-owned subsidiary of AES; (ii) a
$200  million  subordinated  bridge loan to AES (the "AES Bridge  Loan");  (iii)
non-recourse  project debt; (iv) borrowings under AES's Revolver and (v) cash on
hand.

     These projects are subject to a number of risks  including those related to
financing,  construction and contract compliance,  and there can be no assurance
that they will be completed successfully.


Other Events

     On February 10, 1998,  AES  announced  that it had sold its 20% interest in
Hazelwood Power Partners to National Power PLC for approximately  A$205 million.
Hazelwood Power Partners operates a 1,600 MW coal-fired power plant in Victoria,
Australia. AES had acquired its interest in Hazelwood as part of its acquisition
of the international businesses of Destec Energy, Inc. in June 1997.

     In  February  1998,  AES repaid the  remaining  balances  on both the CEMIG
Bridge and ESEBA Bridge loans through the  combination of: (i) the sale of AES's
interest in Hazelwood;  (ii) the  replacement  of cash reserves with a letter of
credit at one of AES's projects and; (iii) borrowings under the Revolver.

     On  January  9,  1998,  the  Southern  Company  exercised  its  option  for
approximately  $114 million  which was used  entirely to partially  pay down the
CEMIG Bridge to $106 million.

     In September 1997, AES began construction on the AES Parana project, an 830
MW  gas-fired,  combined  cycle power  plant.  AES Parana will be located in San
Nicolas, Argentina, adjacent to Central Termica San Nicolas, in which AES owns a
controlling interest. AES Parana is in the final stages of arranging for project
financing  for the  facility.  AES Parana has entered  into a lump sum,  turnkey
construction  contract with Nichimen Corporation and Mitsubishi Heavy Industries
for the plant. A portion of the fuel will be supplied by Total Corporation under
a long term,  risk  management  contract.  Project  output will be sold into the
Argentine electric market.  Total capital cost is estimated at $440 million, and
the project is expected to commence commercial operation in 2000.

     Also in September,  AES's 100% owned  subsidiary,  AES Mt.  Stuart,  raised
A$103.50  million   (approximately  US$75.5  million)  of  non-recourse  project
financing for its 288 MW kerosene-fired  simple cycle power plant in Townsville,
Queensland,  Australia.  The project debt facility was solely  under-written  by
Societe  Generale  Australia  Ltd.  and is  comprised  of a 10-year term loan, a
letter of credit  facility and a  short-term  revolving  cash advance  facility.
Low-cost   peaking  power  from  the  plant  will  be  sold  to  the  Queensland
Transitional Power Trading Corporation under a 10-year power purchase agreement.
A turnkey construction agreement has been signed with Nichimen Corporation,  and
the  major   equipment  will  be  supplied  by  Mitsubishi   Heavy   Industries.
Construction  of the plant  started  during  the  fourth  quarter of 1997 and is
scheduled to be completed on January 1, 1999.


     In July 1997, the Company  announced a two for one stock split, in the form
of a stock dividend, for holders of record on July 28, 1997 of its Common Stock,
par value $.01 per share, which was paid on August 28, 1997.

     In the same month, the Company issued  approximately $325 million of senior
subordinated  notes due 2007 with an 8 3/8% interest rate per annum in a private
placement.  The Company used the net proceeds of  approximately  $315 million to
repay amounts outstanding under the AES Bridge Loan, to redeem the Company's $75
million  9 3/4%  senior  subordinated  notes  due 2000  and to repay  pro rata a
portion of the amounts  outstanding under the ESEBA Bridge and the CEMIG Bridge.
The ESEBA Bridge and the CEMIG  Bridge have been  refinanced  and are  currently
$180 million and $220 million, respectively.

     Also in July, the Company sold 4.5 million shares of its common stock (on a
pre-split basis) for gross proceeds of approximately  $359 million or $79.75 per
share. The Company used the net proceeds of approximately  $350 million to repay
pro rata a portion of the  amounts  outstanding  under the ESEBA  Bridge and the
CEMIG Bridge.

     Unless otherwise indicated, all share numbers and per share amounts in this
Prospectus have been restated to reflect the stock split.

     The pro forma information  incorporated by reference in this Prospectus has
been adjusted for the  Company's  issuance of $325 million  aggregate  principal
amount of 8 3/8% Senior  Subordinated Notes due 2007 and 9 million shares of AES
Common Stock, the redemption of $75 million 9 3/4% Senior Subordinated Notes and
the repayment  and  reborrowing  of the CEMIG Bridge and ESEBA  Bridge,  in each
case,  during  the third  quarter  of 1997  (collectively,  the  "Third  Quarter
Financings"),   the  CEMIG  Acquisition,   the  Destec  Acquisition,  the  ESEBA
Acquisition,  the CEEE Acquisition, and the Original Offering and the concurrent
offering by the Company of  $375,000,000  of its Senior  Subordinated  Notes due
2007  and   $125,000,000  of  its  Senior   Subordinated   Debentures  due  2027
(collectively,  the "Initial Offerings") and the application of the net proceeds
therefrom (collectively, the "Adjustments") but does not reflect the sale of the
Company's  interest in  Hazelwood,  the  repayment of the CEMIG Bridge and ESEBA
Bridge Loans or the borrowings  under the Revolver in February 1998 as described
in "-- Other Events".  Complete unaudited pro forma financial information giving
effect to the Adjustments is incorporated by reference to the Company's  Current
Report on Form 8-K filed on January 9, 1998.

                                TECONS OFFERING

SECURITIES   OFFERED.....  6,000,000 $2.75 Term Convertible Securities, Series B
                           ("TECONS" or "Preferred Securities").

ISSUER...................  AES Trust II, a  Delaware  business  trust.  The sole
                           assets  of the  Trust  consist  of the  5.50%  Junior
                           Subordinated  Convertible  Debentures  due 2012  (the
                           "Junior Subordinated Debentures") of AES.

GUARANTOR................  The AES Corporation, a Delaware corporation.

DISTRIBUTIONS............  Distributions  on the TECONS will accrue from October
                           29,  1997 and will be  payable  at an annual  rate of
                           $2.75  per  TECONS.   Subject  to  the   Distribution
                           deferral  provisions  described below,  Distributions
                           will be payable  quarterly in arrears on the last day
                           of each  calendar  quarter,  commencing  December 31,
                           1997. Because  Distributions on the TECONS constitute
                           interest  for  U.S.   federal  income  tax  purposes,
                           corporate  holders  thereof will not be entitled to a
                           dividends-received deduction.

DISTRIBUTION DEFERRAL
PROVISIONS..............   The ability of the Trust to pay  Distributions on the
                           TECONS is solely dependent on the receipt of interest
                           payments   from  AES  on  the   Junior   Subordinated
                           Debentures. So long as AES shall not be in default in
                           the payment of  interest  on the Junior  Subordinated
                           Debentures,  AES has the right to defer  payments  of
                           interest on the Junior  Subordinated  Debentures from
                           time to time for  successive  Extension  Periods  not
                           exceeding  20  consecutive  quarters  for  each  such
                           period;  provided  that no  such  period  may  extend
                           beyond the stated maturity of the Junior Subordinated
                           Debentures.  Quarterly  Distributions  on the  TECONS
                           would be deferred by the Trust (but would continue to
                           accumulate  quarterly and accrue  interest) until the
                           end  of  any   such   Extension   Period.   Upon  the
                           termination of an Extension Period, payment is due on
                           all  accrued   and  unpaid   amounts  on  the  Junior
                           Subordinated  Debentures  and upon such payment,  the
                           Trust would be required  to pay all  accumulated  and
                           unpaid  Distributions.  AES will  give  notice of its
                           deferral of an interest payment to the Trust no later
                           than ten  business  days prior to the related  record
                           date (unless the Property  Trustee  shall be the sole
                           holder  of the  Junior  Subordinated  Debentures,  in
                           which  case  notice  will be given no later  than one
                           business  day  prior to the  earlier  of (i) the next
                           succeeding  Interest Payment Date (as defined herein)
                           or (ii) the  date the  Company  is  required  to give
                           notice of the related record date).  See "Description
                           of the TECONS --  Distributions"  and "Description of
                           the  Junior  Subordinated  Debentures  --  Option  to
                           Extend Interest  Payment Period" and "Risk Factors --

                           of Extension."  If a deferral of an interest  payment
                           occurs,  the holders of the TECONS  will  continue to
                           accrue income for U.S. federal income tax purposes in
                           advance of any corresponding cash  Distribution.  See
                           "Certain  Federal  Tax  Consequences  --  Accrual  of
                           Original Issue  Discount" and "Risk Factors -- Option
                           to Extend  Interest  Payment  Period;  Tax  Impact of
                           Extension."

RIGHTS UPON DEFERRAL OF
 DISTRIBUTIONS...........  During any period in which  interest  payments on the
                           Junior Subordinated Debentures are deferred, interest
                           will  accrue on the  Junior  Subordinated  Debentures
                           (compounded  quarterly)  and quarterly  Distributions
                           will continue to accumulate with interest thereon (to
                           the  extent  permitted  by  applicable  law)  at  the
                           Distribution  rate,  compounded  quarterly.  AES  has
                           agreed, among other things, not to declare or pay any
                           dividend on its common  stock or  preferred  stock or
                           make any  guarantee  payments  with  respect  thereto
                           during  any  Extension  Period,   provided  that  the
                           foregoing  shall  not  apply to any  stock  dividends
                           payable in AES Common Stock.  See "Description of the
                           Junior  Subordinated  Debentures  -- Option to Extend
                           Interest  Payment Period" and "Risk Factors -- Option
                           to Extend  Interest  Payment  Period;  Tax  Impact of
                           Extension."

CONVERSION  RIGHTS.......  Each TECONS is  convertible  at any time prior to the
                           close of business on  September  30, 2012 (or, in the
                           case of TECONS  called for  redemption,  prior to the
                           close of  business  on the  Business  Day (as defined
                           herein) prior to the applicable  redemption  date) at
                           the  option of the holder  into  shares of AES Common
                           Stock,  at the rate of 0.8914  shares  of AES  Common
                           Stock for each  TECONS  (equivalent  to a  conversion
                           price  of  $56.09  per  share of AES  Common  Stock),
                           subject to adjustment in certain  circumstances.  The
                           reported  last sale price of AES Common  Stock on the
                           NYSE  Composite  Tape on February 10, 1998 was $41.25
                           per share.  In  connection  with any  conversion of a
                           TECONS, the Conversion Agent (as defined herein) will
                           exchange  such TECONS for the  appropriate  principal
                           amount of the Junior Subordinated Debentures held for
                           the  Trust  and   immediately   convert  such  Junior
                           Subordinated  Debentures  into AES Common  Stock.  No
                           fractional  shares of AES Common Stock will be issued
                           as a result of  conversion,  but in lieu thereof such
                           fractional  interest will be paid by AES in cash. See
                           "Description of the TECONS -- Conversion Rights."

LIQUIDATION  AMOUNT......  In the event of any liquidation of the Trust, holders
                           will be  entitled  to receive  $50 per TECONS plus an
                           amount equal to any accrued and unpaid  Distributions
                           thereon  to  the  date  of  payment,   unless  Junior
                           Subordinated   Debentures  are  distributed  to  such
                           holders.   See   "Description   of  the   TECONS   --
                           Liquidation Distribution Upon Dissolution."

REDEMPTION...............  The Junior Subordinated Debentures will be redeemable
                           for cash,  at the option of the Company,  in whole or
                           in part,  from time to time on or after September 30,
                           2000 at the prices specified herein or at any time in
                           certain  circumstances  upon the  occurrence of a Tax
                           Event  at a  redemption  price  equal  to 100% of the
                           principal  amount to be redeemed plus any accrued and
                           unpaid   interest   thereon,   including   Compounded
                           Interest,  if any, to the date of redemption.  If the
                           Company redeems Junior Subordinated  Debentures,  the
                           Trust must redeem,  at the  Redemption  Price,  Trust
                           Securities  having an  aggregate  liquidation  amount
                           equal to the aggregate principal amount of the

<PAGE>

                           Junior  Subordinated   Debentures  so  redeemed.  The
                           TECONS will not have a stated maturity date, although
                           they will be subject to mandatory redemption upon the
                           repayment of the Junior  Subordinated  Debentures  at
                           their stated  maturity  (September  30,  2012),  upon
                           acceleration,  earlier  redemption or otherwise.  See
                           "Description  of the TECONS -- Mandatory  Redemption"
                           and   "Description   of   the   Junior   Subordinated
                           Debentures -- Optional Redemption."


GUARANTEE................  AES will irrevocably and  unconditionally  guarantee,
                           on a  subordinated  basis and to the extent set forth
                           herein,  the  payment in full of (i) any  accrued and
                           unpaid  Distributions  and the  amount  payable  upon
                           redemption of the TECONS to the extent AES has made a
                           payment  to  the  Property  Trustee  of  interest  or
                           principal on the Junior  Subordinated  Debentures and
                           (ii) generally,  the liquidation amount of the TECONS
                           to the  extent  the Trust has  assets  available  for
                           distribution to holders of TECONS. The Guarantee will
                           be unsecured  and will be  subordinate  and junior in
                           right of payment to all other  liabilities of AES and
                           will rank  pari  passu in right of  payment  with the
                           most  senior  preferred  stock  issued,  from time to
                           time,  if  any,  by  AES.  See  "Description  of  the
                           Guarantee."

VOTING  RIGHTS...........  Generally,  holders of the  TECONS  will not have any
                           voting rights.  If (i) the Property  Trustee fails to
                           enforce  its  rights  under the  Junior  Subordinated
                           Debentures or (ii) the Guarantee  Trustee (as defined
                           herein)   fails  to  enforce  its  rights  under  the
                           Guarantee,   a  record   holder  of  the  TECONS  may
                           institute a legal proceeding  directly against AES to
                           enforce such rights  without  first  instituting  any
                           legal proceeding  against any other person or entity.
                           Notwithstanding the foregoing,  if an Indenture Event
                           of  Default  (as  defined   herein)   occurs  and  is
                           continuing and is  attributable to the failure of AES
                           to  pay   interest   or   principal   on  the  Junior
                           Subordinated  Debentures  or AES has failed to make a
                           Guarantee  Payment (as defined  herein),  a holder of
                           the  TECONS  may  directly   institute  a  proceeding
                           against  AES for  enforcement  of such  payment.  See
                           "Description  of the TECONS -- Voting Rights" and "--
                           Declaration Events of Default."

SPECIAL EVENT DISTRIBUTION;
 TAX EVENT REDEMPTION....  Upon the  occurrence  of a Special  Event (as defined
                           herein), except in certain limited circumstances, AES
                           may  cause the  Trust to be  dissolved  and cause the
                           Junior  Subordinated  Debentures to be distributed to
                           the holders of the TECONS. In the case of a Tax Event
                           (as defined herein),  AES may also elect to cause the
                           TECONS  to  remain  outstanding  and  pay  Additional
                           Interest (as defined  herein),  if any, on the Junior
                           Subordinated  Debentures.  In  certain  circumstances
                           upon  the  occurrence  of a  Tax  Event,  the  Junior
                           Subordinated  Debentures  may be  redeemed  by AES at
                           100% of the principal amount thereof plus accrued and
                           unpaid  interest  thereon.  See  "Description  of the
                           TECONS -- Special Event Redemption or Distribution."

JUNIOR SUBORDINATED
 DEBENTURES OF AES.......  The Junior  Subordinated  Debentures  will  mature on
                           September 30, 2012 and will bear interest at the rate
                           of 5.50% per annum,  payable quarterly in arrears. So
                           long as AES shall not be in default in the payment of
                           interest on the Junior Subordinated  Debentures,  AES
                           has the right to defer  payments  of  interest on the
                           Junior Subordinated  Debentures from time to time for
                           successive   periods  not  exceeding  20  consecutive
                           quarters for each such period;  provided that no such
                           period may extend  beyond the stated  maturity of the
                           Junior   Subordinated   Debentures.   Prior   to  the
                           termination of any Extension Period,  AES may pay all
                           or a  portion  of the  accrued  Distributions  or may
                           further   defer   interest   payments   provided  the
                           Extension Period, as previously and further extended,
                           does not exceed 20 consecutive  quarters.  During any
                           Extension  Period no interest  shall be due, but such
                           interest   shall  continue  to  accrue  and  compound
                           quarterly.  Upon termination of the Extension Period,
                           payment is due on all  accrued  and  unpaid  amounts.
                           After the  payment of all amounts  then due,  AES may
                           commence  a new  Extension  Period,  subject  to  the
                           conditions  of this  paragraph.  During any Extension
                           Period,  AES will be prohibited from paying dividends
                           on any of its  common  stock  or  preferred  stock or
                           making any guarantee  payments with respect  thereto;
                           provided  that the  foregoing  shall not apply to any
                           stock dividends  payable in Common Stock. The payment
                           of principal and interest on the Junior  Subordinated
                           Debentures  will be  subordinated in right of payment
                           to all  present  and future  Senior and  Subordinated
                           Debt of AES. In addition,  payment of  principal  and
                           interest on the Junior  Subordinated  Debentures will
                           be  structurally  subordinated  to the liabilities of
                           AES' subsidiaries. As of September 30, 1997, on a pro
                           forma basis after giving  effect to the  Adjustments,
                           the   Company   had  $1.3   billion   of  Senior  and
                           Subordinated  Debt (which includes letters of credit)
                           outstanding.  In addition, on a pro forma basis after
                           given  effect  to  the  Adjustments,   the  Company's
                           subsidiaries  had debt of $4.0 billion,  to which the
                           Junior   Subordinated   Debentures  are   effectively
                           subordinated.  The  Indenture  (as  defined  herein),
                           under which the Junior  Subordinated  Debentures will
                           be  issued,  does not limit the  aggregate  amount of
                           Senior and Subordinated  Debt that may be incurred by
                           AES  and  does  not  limit  the  liabilities  of  the
                           Company's   subsidiaries.   The  Junior  Subordinated
                           Debentures  will  have  provisions  with  respect  to
                           interest, optional redemption and conversion into AES
                           Common  Stock and certain  other terms  substantially
                           similar  or  analogous  to those of the  TECONS.  See
                           "Description of the Junior  Subordinated  Debentures"

                                 RISK FACTORS

     Prospective  purchasers  of the TECONS  should read this entire  Prospectus
carefully.  The following  factors should be considered  carefully in evaluating
AES and its business before purchasing the TECONS offered by this Prospectus.


LEVERAGE AND SUBORDINATION

     The  Company  and  its  subsidiaries  had  approximately  $3.9  billion  of
outstanding  indebtedness  at September  30, 1997.  As a result of the Company's
level of debt, the Company might be significantly limited in its ability to meet
its debt service  obligations,  to finance the  acquisition  and  development of
additional  projects,  to compete  effectively or to operate  successfully under
adverse  economic  conditions.  As of  September  30,  1997,  the  Company had a
consolidated ratio of total debt to total book capitalization (including current
debt) of approximately 70%.

     The Junior  Subordinated  Debentures will be subordinated to all Senior and
Subordinated  Debt  including,  but not limited to, the  Company's  $600 million
Revolver.  The obligations of AES under the Guarantee are subordinate and junior
in right of payment to all liabilities of AES and pari passu in right of payment
with the most senior preferred stock issued,  from time to time, if any, by AES.
As of  September  30,  1997,  on a pro forma  basis after  giving  effect to the
Adjustments,  the Company had approximately $1.3 billion in aggregate  principal
amount of Senior and Subordinated Debt.

     Upon  any  payment  or   distribution  of  assets  to  creditors  upon  any
liquidation, dissolution, winding up, receivership,  reorganization,  assignment
for the  benefit  of  creditors,  marshaling  of assets and  liabilities  or any
bankruptcy,  insolvency or similar  proceedings  of the Company,  the holders of
Senior and Senior Subordinated Debt will first be entitled to receive payment in
full of all amounts due or to become due under all Senior and Subordinated  Debt
before the  holders of the Junior  Subordinated  Debentures  will be entitled to
receive any payment in respect of the principal of, premium, if any, or interest
on such Junior  Subordinated  Debentures.  No payments on account of  principal,
premium,  if any, or interest in respect of the Junior  Subordinated  Debentures
may be made if there  shall have  occurred  and be  continuing  a default in any
payment under any Senior and Senior  Subordinated Debt or during certain periods
when an event of default under certain Senior and Subordinated  Debt permits the
lenders  thereunder  to  accelerate  the  maturing  of such  Senior  and  Senior
Subordinated  Debt.  See  "Description  of  Junior  Subordinated  Debentures  --
Subordination."  The Guarantee will rank (i)  subordinate and junior in right of
payment  to  all  other  liabilities  of  the  Company,   including  the  Junior
Subordinated  Debentures,  except those made pari passu or  subordinate by their
terms and (ii) pari passu in right of  payment  with the most  senior  preferred
stock issued, from time to time, if any, by the Company. See "Description of the
Guarantee."

     The Junior Subordinated Debentures will be effectively  subordinated to the
indebtedness and other  obligations  (including trade payables) of the Company's
subsidiaries. At September 30, 1997, on a pro forma basis after giving effect to
the Adjustments,  the indebtedness and obligations of the Company's subsidiaries
aggregated  approximately  $4.0  billion.  The  ability  of the  Company  to pay
principal  of,  premium,  if  any,  and  interest  on  the  Junior  Subordinated
Debentures will be dependent upon the receipt of funds from its  subsidiaries by
way of dividends,  fees, interest, loans or otherwise. There are no terms in the
Junior  Subordinated  Debentures,  the  TECONS or the  Guarantee  that limit the
Company's or its subsidiaries' ability to incur additional indebtedness. Most of
the  Company's  subsidiaries  with  interests  in  power  generation  facilities
currently  have in  place  arrangements  that  restrict  their  ability  to make
distributions  to the  Company by way of  dividends,  fees,  interest,  loans or
otherwise.  The Company's  subsidiaries are separate and distinct legal entities
and have no obligation, contingent or otherwise, to pay any amounts due pursuant
to the  Junior  Subordinated  Debentures  or the  TECONS  or to make  any  funds
available therefor,  whether by dividends,  loans or other payments,  and do not
guarantee  the payment of interest on or  principal  of the Junior  Subordinated
Debentures or the TECONS.  Any right of the Company to receive any assets of any
of its subsidiaries upon any liquidation, dissolution, winding up, receivership,
reorganization,  assignment  for the benefit of creditors,  marshaling of assets
and  liabilities  or any  bankruptcy,  insolvency or similar  proceedings of the
Company  (and the  consequent  right of the  holders of the Junior  Subordinated
Debentures and the TECONS to participate in the distribution



                                       16
<PAGE>

of,  or to realize proceeds from, those assets) will be effectively subordinated
to  the claims of any such subsidiary's creditors (including trade creditors and
holders  of  debt  issued  by  such  subsidiary). The Company currently conducts
substantially  all  of its operations through its subsidiaries. See "Description
of  the  Guarantee"  and  "Description  of the Junior Subordinated Debentures --
Subordination."



DOING BUSINESS OUTSIDE THE UNITED STATES

     The  Company's  involvement  in the  development  of new  projects  and the
acquisition  of  existing  plants in  locations  outside  the  United  States is
increasing  and  most  of the  Company's  current  development  and  acquisition
activities are for projects and plants  outside the United States.  The Company,
through subsidiaries,  affiliates and joint ventures, has ownership interests in
75 power plants  outside the United  States in operation or under  construction.
Thirty-nine  of such power  plants are located in Brazil;  nine in the  People's
Republic of China;  seven in  Kazakhstan;  six in Argentina;  five in the United
Kingdom;  three in Hungary; two in Pakistan; and one in each of the Netherlands,
Canada, Australia and the Dominican Republic.

     The  financing,  development  and operation of projects  outside the United
States entail  significant  political and  financial  uncertainties  (including,
without  limitation,  uncertainties  associated  with  first-time  privatization
efforts in the countries involved, currency exchange rate fluctuations, currency
repatriation  restrictions,  currency  inconvertibility,  political instability,
civil  unrest,  and  expropriation)  and  other  credit  quality,  liquidity  or
structural issues that have the potential to cause substantial delays in respect
of or  material  impairment  of the  value of the  project  being  developed  or
operated, which AES may not be capable of fully insuring or hedging against. The
ability to obtain financing on a commercially  acceptable  non-recourse basis in
developing  nations may also  require  higher  investments  by the Company  than
historically  have been the case. In addition,  financing in countries with less
than  investment  grade  sovereign  credit ratings may also require  substantial
participation by multilateral financing agencies. There can be no assurance that
such financing can be obtained when needed.

     The uncertainty of the legal  environment in certain countries in which the
Company,  its  subsidiaries  and  its  affiliates  are or in the  future  may be
developing,  constructing  or  operating  could make it more  difficult  for the
Company to enforce  its  respective  rights  under  agreements  relating to such
projects.  In addition,  the laws and regulations of certain countries may limit
the Company's  ability to hold a majority  interest in some of the projects that
it may develop or acquire.  International  projects owned by the Company may, in
certain cases, be expropriated by applicable governments.  Although AES may have
legal recourse in enforcing its rights under  agreements and recovering  damages
for breaches thereof,  there can be no assurance that any such legal proceedings
will be successful.


COMPETITION

     The global power production  market is characterized by numerous strong and
capable   competitors,   many  of  whom  may  have  extensive  and   diversified
developmental or operating experience (including both domestic and international
experience)  and  financial  resources  similar to or greater  than the Company.
Further,  in recent years, the power production  industry has been characterized
by strong and increasing  competition with respect to both obtaining power sales
agreements and acquiring  existing power generation  assets. In certain markets,
these  factors  have caused  reductions  in prices  contained in new power sales
agreements  and,  in many  cases,  have  caused  higher  acquisition  prices for
existing  assets  through  competitive  bidding  practices.   The  evolution  of
competitive   electricity  markets  and  the  development  of  highly  efficient
gas-fired  power plants have also caused,  or are  anticipated  to cause,  price
pressure in certain  power  markets  where the Company  sells or intends to sell
power. There can be no assurance that the foregoing competitive factors will not
have a material adverse effect on the Company.


DEVELOPMENT UNCERTAINTIES

     The  majority of the  projects  that AES develops are large and complex and
the completion of any such project is subject to substantial risks.  Development
can require the Company to expend significant sums for preliminary  engineering,
permitting, legal and other expenses in preparation for competitive 


                                       17
<PAGE>

bids  which the  Company  may not win or before it can be  determined  whether a
project is  feasible,  economically  attractive  or  capable of being  financed.
Successful  development and construction is contingent upon, among other things,
negotiation on terms  satisfactory to the Company of engineering,  construction,
fuel supply and power sales contracts with other project  participants,  receipt
of required  governmental  permits and  consents and timely  implementation  and
satisfactory completion of construction. There can be no assurance that AES will
be able to obtain new power sales contracts,  overcome local opposition, if any,
obtain the necessary site agreements,  fuel supply and ash disposal  agreements,
construction  contracts,  steam sales  contracts,  licenses and  certifications,
environmental  and other  permits and  financing  commitments  necessary for the
successful  development  of  its  projects.  There  can  be  no  assurance  that
development  efforts  on  any  particular  project,  or  the  Company's  efforts
generally,  will be successful. If these development efforts are not successful,
the Company may abandon a project under development. At the time of abandonment,
the  Company  would  expense  all  capitalized  development  costs  incurred  in
connection  therewith  and could incur  additional  losses  associated  with any
related contingent  liabilities.  The future growth of the Company is dependent,
in part,  upon the  demand for  significant  amounts  of  additional  electrical
generating  capacity and its ability to obtain  contracts to supply  portions of
this capacity.  Any material  unremedied delay in, or unsatisfactory  completion
of,  construction of the Company's projects could, under certain  circumstances,
have an  adverse  effect  on the  Company's  ability  to meet  its  obligations,
including  the payment of  principal  of,  premium,  if any and  interest on the
Notes. The Company also is faced with certain development  uncertainties arising
out of doing  business  outside of the  United  States.  See "-- Doing  Business
Outside the United States."



RISKS ASSOCIATED WITH ACQUISITIONS

     The  Company  has  achieved a  significant  portion  of its growth  through
acquisitions  and  expects  that it will  continue  to grow,  in  part,  through
acquisitions.  During 1997 alone the Company  consummated the ESEBA Acquisition,
the Destec Acquisition,  the CEMIG Acquisition and the CEEE Acquisition in which
the Company  invested an aggregate  of  approximately  $1.9  billion  (excluding
non-recourse  debt).  Although each of the acquired businesses had a significant
operating history at the time of its acquisition by the Company, the Company has
a limited history of owning and operating these businesses. In addition, most of
these  businesses  were  government  owned and some were  operated  as part of a
larger integrated  utility prior to their acquisition by the Company.  There can
be no assurances that the Company will be successful in  transitioning  these to
private  ownership,  that such  businesses  will perform as expected or that the
returns from such businesses will support the  indebtedness  incurred to acquire
them or the capital expenditures needed to develop them.


UNCERTAINTY OF ACCESS TO CAPITAL FOR FUTURE PROJECTS

     Each of AES's projects under development and those independent power supply
businesses it may seek to acquire may require  substantial  capital  investment.
Continued  access to capital  with  acceptable  terms is necessary to assure the
success of future  projects and  acquisitions.  AES has  substantially  utilized
project  financing  loans  to fund  the  capital  expenditures  associated  with
constructing and acquiring its electric power plants and related assets. Project
financing borrowings have been substantially  non-recourse to other subsidiaries
and affiliates and to AES as the parent company and are generally secured by the
capital stock,  physical assets,  contracts and cash flow of the related project
subsidiary  or  affiliate.  The  Company  intends  to  continue  to seek,  where
possible,  such  non-recourse  project  financing in connection  with the assets
which the Company or its affiliates may develop,  construct or acquire. However,
depending on market  conditions  and the unique  characteristics  of  individual
projects,  such  financing  may not be  available or the  Company's  traditional
providers of project financing, particularly multinational commercial banks, may
seek higher borrowing spreads and increased equity contributions. 


     Furthermore,  because of the reluctance of commercial lending  institutions
to provide non-recourse  project financing  (including financial  guarantees) in
certain less developed economies,  the Company, in such locations,  has and will
continue to seek  direct or  indirect  (through  credit  support or  guarantees)
project   financing  from  a  limited  number  of   multilateral   or  bilateral
international  financial  institutions or agencies.  As a precondition to making
such project financing available, these institutions may also re-



                                       18
<PAGE>

quire  governmental  guarantees of certain project and sovereign  related risks.
Depending on the policies of specific  governments,  such  guarantees may not be
offered  and as a result,  AES may  determine  that  sufficient  financing  will
ultimately not be available to fund the related project.

     In addition to the project  financing  loans, if available,  AES provides a
portion,  or in certain  instances  all, of the  remaining  long-term  financing
required to fund development,  construction,  or acquisition.  These investments
have  generally  taken  the form of  equity  investments  or  loans,  which  are
subordinated to the project  financing  loans.  The funds for these  investments
have been  provided  by cash  flows from  operations  and by the  proceeds  from
borrowings  under the  short-term  credit  facilities  and  issuances  of senior
subordinated notes, convertible debentures and common stock of the Company.

     The Company's  ability to arrange for financing on either a fully  recourse
or a  substantially  non-recourse  basis  and  the  costs  of such  capital  are
dependent on numerous  factors,  including  general  economic and capital market
conditions, the availability of bank credit, investor confidence in the Company,
the continued  success of current  projects and provisions of tax and securities
laws which are conducive to raising capital in this manner. Should future access
to capital not be  available,  AES may decide not to build new plants or acquire
existing  facilities.  While a  decision  not to build  new  plants  or  acquire
existing  facilities  would not affect the results of  operations  of AES on its
currently operating facilities or facilities under construction, such a decision
would affect the future growth of AES.




DEPENDENCE ON UTILITY CUSTOMERS AND CERTAIN PROJECTS

     The  nature of most of AES's  power  projects  is such  that each  facility
generally  relies on one power sales  contract  with a single  customer  for the
majority, if not all, of its revenues over the life of the power sales contract.
During  1996,  five  customers,   including  CL&P,  a  subsidiary  of  Northeast
Utilities,  accounted for 73% of the Company's  consolidated total revenues. The
prolonged  failure  of any one  utility  customer  to  fulfill  its  contractual
obligations could have a substantial  negative impact on AES's primary source of
revenues.  AES has  sought to reduce  this risk in part by  entering  into power
sales  contracts with utilities or other  customers of strong credit quality and
by locating  its plants in different  geographic  areas in order to mitigate the
effects of regional economic downturns.

     Four of the Company's plants collectively represented  approximately 39% of
AES's consolidated total assets at December 31, 1996 and generated approximately
67% of AES's consolidated total revenues for the year ended December 31, 1996.

     Sales to Connecticut Light & Power Company ("CL&P")  represented 16% of the
Company's total revenues in 1996. Moody's Investor Service Inc.  ("Moody's") and
Standard & Poor's  Corporation  ("S&P") have recently  downgraded  CL&P's senior
secured  long-term  debt from  Baa3/BBB-  to Ba2/ BB, and S&P has placed CL&P on
watch for possible  downgrade.  As a result of  regulatory  action by the Public
Service  Commission of New  Hampshire,  Moody's and S&P recently  downgraded the
senior unsecured debt of Northeast Utilities, the parent of CL&P, from Ba2/BB to
B1/B+ and S&P has placed Northeast Utilities on watch for possible downgrade.


REGULATORY UNCERTAINTY

     AES's  cogeneration  operations  in the United  States  are  subject to the
provisions  of  various  laws and  regulations,  including  the  Public  Utility
Regulatory  Policies Act of 1978, as amended  ("PURPA")  and the Public  Utility
Holding Company Act of 1935, as amended ("PUHCA").  PURPA provides to qualifying
facilities  ("QFs")  certain  exemptions  from  substantial  federal  and  state
legislation,  including  regulation as public utilities.  PUHCA regulates public
utility  holding  companies and their  subsidiaries.  AES is not and will not be
subject to regulation  as a holding  company under PUHCA as long as the domestic
power plants it owns are QFs under PURPA.  QF status is  conditioned  on meeting
certain criteria, and would be jeopardized,  for example, by the loss of a steam
customer.  The Company believes that, upon the occurrence of an event that would
threaten the QF status of one of its domestic plants,  it would be able to react
in a manner that would  avoid the loss of QF status  (such as by  replacing  the
steam customer).  In the event the Company were unable to avoid the loss of such
status for one of its plants,  to avoid public utility  holding  company status,
AES could apply to the Federal Energy Regula-



                                       19
<PAGE>

tory  Commission  ("FERC")  to obtain  status as an Exempt  Wholesale  Generator
("EWG"),  or could  restructure the ownership of the project  subsidiary.  EWGs,
however,  are subject to broader  regulation by FERC and may be subject to state
public utility commissions  regulation  regarding non-rate matters. In addition,
any restructuring of a project subsidiary could result in, among other things, a
reduced financial  interest in such subsidiary,  which could result in a gain or
loss on the  sale  of the  interest  in such  subsidiary,  the  removal  of such
subsidiary from the consolidated income tax group or the consolidated  financial
statements  of the  Company,  or an  increase  or  decrease  in the  results  of
operations of the Company.

     The United States Congress is considering  proposed legislation which would
repeal  PURPA  entirely,  or at least  repeal the  obligation  of  utilities  to
purchase  from QFs.  There is strong  support  for  grandfathering  existing  QF
contracts  if such  legislation  is  passed,  and  also  support  for  requiring
utilities  to conduct  competitive  bidding for new electric  generation  if the
PURPA purchase obligation is eliminated. Various bills have also proposed repeal
of  PUHCA.  Repeal  of  PUHCA  would  allow  both  independents  and  vertically
integrated  utilities to acquire retail  utilities in the United States that are
geographically  widespread, as opposed to the current limitations of PUHCA which
require  that retail  electric  systems be capable of physical  integration.  In
addition,  registered  holding  companies  would be free to acquire  non-utility
businesses,  which they may not do now, with certain limited exceptions.  In the
event of a PUHCA repeal,  competition  for  independent  power  generators  from
vertically  integrated  utilities would likely increase.  Repeal of PURPA and/or
PUHCA may or may not be part of  comprehensive  legislation to  restructure  the
electric  utility  industry,  allow  retail  competition,  and  deregulate  most
electric rates. The effect of any such repeal cannot be predicted,  although any
such repeal could have a material adverse effect on the Company.


ELECTRIC UTILITY INDUSTRY RESTRUCTURING PROPOSALS

     The FERC and many state utility commissions are currently studying a number
of proposals to restructure the electric  utility industry in the United States.
Such  restructuring  would permit  utility  customers  to choose  their  utility
supplier in a competitive  electric energy market.  The FERC issued a final rule
in April  1996  which  requires  utilities  to  offer  wholesale  customers  and
suppliers open access on utility  transmission  lines, on a comparable  basis to
the utilities' own use of the lines.  The final rule is subject to rehearing and
may become the subject of court  litigation.  Many  utilities have already filed
"open  access"  tariffs.  The  utilities  contend that they should  recover from
departing  customers their fixed costs that will be "stranded" by the ability of
their wholesale  customers (and perhaps  eventually,  their retail customers) to
choose new electric power  suppliers.  The FERC final rule endorses the recovery
of  legitimate  and  verifiable  "stranded  costs."  These may include the costs
utilities are required to pay under many QF contracts  which the utilities  view
as excessive  when  compared  with current  market  prices.  Many  utilities are
therefore  seeking ways to lower these contract  prices or rescind the contracts
altogether,  out of concern that their shareholders will be required to bear all
or part of such  "stranded"  costs.  Some  utilities  have engaged in litigation
against QFs to achieve these ends.

     In addition,  future United States  electric  rates may be deregulated in a
restructured  United States electric utility industry and increased  competition
may result in lower rates and less profit for United States electricity sellers.
Falling  electricity  prices and  uncertainty as to the future  structure of the
industry is inhibiting  United  States  utilities  from entering into  long-term
power purchase  contracts.  The effect of any such  restructuring on the Company
cannot be  predicted,  although  any such  restructuring  could  have a material
adverse effect on the Company.


LITIGATION AND REGULATORY PROCEEDINGS

     From time to time, the Company and its affiliates are parties to litigation
and regulatory  proceedings.  Investors  should review the  descriptions of such
matters contained in the Company's  Annual,  Quarterly and Current Reports filed
with the  Commission  and  incorporated  by  reference  herein.  There can be no
assurances  that the outcome of such  matters  will not have a material  adverse
effect on the Company.



                                       20
<PAGE>


BUSINESS SUBJECT TO STRINGENT ENVIRONMENTAL REGULATIONS

     AES's  activities  are subject to  stringent  environmental  regulation  by
federal,  state, local and foreign  governmental  authorities.  For example, the
Clean Air Act  Amendments  of 1990 impose more  stringent  standards  than those
previously  in  effect,  and  require  states to impose  permit  fees on certain
emissions. Congress and other foreign governmental authorities also may consider
proposals to restrict or tax certain  emissions.  These  proposals,  if adopted,
could impose additional costs on the operation of AES's power plants.  There can
be no  assurance  that AES would be able to recover all or any  increased  costs
from its  customers  or that its  business,  financial  condition  or results of
operations  would not be materially and adversely  affected by future changes in
domestic or foreign environmental laws and regulations. The Company has made and
will   continue  to  make  capital  and  other   expenditures   to  comply  with
environmental  laws  and  regulations.  There  can  be no  assurance  that  such
expenditures will not have a material adverse effect on the Company's  financial
statements.


CONTROL BY EXISTING STOCKHOLDERS

     As of September 30, 1997,  AES's two founders,  Roger W. Sant and Dennis W.
Bakke, and their immediate  families together owned  beneficially  approximately
22.1% of the  outstanding  AES  Common  Stock.  As a result  of their  ownership
interests,  Messrs.  Sant and Bakke may be able to  significantly  influence  or
exert  control over the affairs of AES,  including the election of the Company's
directors.  As of September  30, 1997,  all of AES's  officers and directors and
their immediate families together owned beneficially  approximately 29.2% of the
outstanding  AES Common Stock.  To the extent that they decide to vote together,
these  stockholders  would be able to  significantly  influence  or control  the
election of AES's  directors,  the management and policies of AES and any action
requiring stockholder approval, including significant corporate transactions.


ADHERENCE TO AES'S PRINCIPLES -- POSSIBLE IMPACT ON RESULTS OF OPERATIONS

     A  core  part  of  AES's  corporate  culture  is a  commitment  to  "shared
principles":  to act with integrity,  to be fair, to have fun and to be socially
responsible.  The Company seeks to adhere to these  principles not as a means to
achieve economic  success,  but because adherence is a worthwhile goal in and of
itself.  However,  if the Company  perceives a conflict between these principles
and  profits,  the Company will try to adhere to its  principles  -- even though
doing so might  result in  diminished  or foregone  opportunities  or  financial
benefits.


RISK OF FRAUDULENT TRANSFER

     Various fraudulent  conveyance laws have been enacted for the protection of
creditors  and may be applied by a court on behalf of any unpaid  creditor  or a
representative  of AES's  creditors  in a lawsuit  to  subordinate  or avoid the
Junior Subordinated Debentures in favor of other existing or future creditors of
AES.  Under  applicable  provisions  of the U.S.  Bankruptcy  code or comparable
provisions of state  fraudulent  transfer or conveyance laws, if AES at the time
of  issuance  of  the  Junior   Subordinated   Debentures,   (i)  incurred  such
indebtedness  with  intent to  hinder,  delay or defraud  any  present or future
creditor of AES or  contemplated  insolvency with a design to prefer one or more
creditors to the  exclusion in whole or in part of others or (ii)  received less
than reasonably  equivalent value or fair  consideration  for issuing the Junior
Subordinated Debentures and AES (a) was insolvent, (b) was rendered insolvent by
reason of the issuance of the Junior Subordinated Debentures, (c) was engaged or
about to engage in business or a transaction  for which the remaining  assets of
AES  constitute  unreasonably  small  capital  to carry on its  business  or (d)
intended to incur, or believed that it would incur,  debts beyond its ability to
pay  such  debts as they  mature,  then,  in each  case,  a court  of  competent
jurisdiction  could  void,  in  whole  or  in  part,  the  Junior   Subordinated
Debentures.  Among other things,  a legal  challenge of the Junior  Subordinated
Debentures on fraudulent  conveyance grounds may focus on the benefits,  if any,
realized by AES as a result of the  issuance  by AES of the Junior  Subordinated
Debentures.

     The measure of insolvency for purposes of the foregoing will vary depending
upon the law applied in such case.  Generally,  however, AES would be considered
insolvent  if the  sum of its  debts,  including  contingent  liabilities,  were
greater than all of its assets at fair valuation or if the present fair market



                                       21
<PAGE>

value of its assets  were less than the amount that would be required to pay the
probable liability on its existing debts, including contingent  liabilities,  as
they become absolute and mature. There can be no assurance that, after providing
for all prior claims,  there will be sufficient  assets to satisfy the claims of
the holders of the Junior Subordinated Debentures.

     Management  believes that, for purposes of all such insolvency,  bankruptcy
and fraudulent transfer or conveyance laws, the Junior  Subordinated  Debentures
are being incurred without the intent to hinder,  delay or defraud creditors and
for proper  purposes  and in good faith,  and that AES after the issuance of the
Junior Subordinated Debentures will be solvent, will have sufficient capital for
carrying on its business and will be able to pay its debts as they mature. There
can be no assurance, however, that a court passing on such questions would agree
with management's view.


ABILITY OF AES TRUST TO MAKE DISTRIBUTIONS

     The ability of AES Trust to make  distributions  and other  payments on the
TECONS is solely  dependent upon the Company making  interest and other payments
on the Junior  Subordinated  Debentures  deposited  as trust  assets as and when
required. If the Company were not to make distributions or other payments on the
Junior  Subordinated  Debentures  for any reason,  including  as a result of the
Company's  election to defer the payment of interest on the Junior  Subordinated
Debentures  by  extending  the  interest  period  on  the  Junior   Subordinated
Debentures, AES Trust will not make payments on the Trust Securities. In such an
event,  holders of the TECONS would not be able to rely on the  Guarantee  since
distributions and other payments on the TECONS are subject to the Guarantee only
if and to the extent that the Company has made a payment to the Property Trustee
of interest or principal on the Junior Subordinated  Debentures deposited in the
Trust as trust assets. Instead,  holders of TECONS would rely on the enforcement
by the  Property  Trustee  of its  rights as  registered  holder  of the  Junior
Subordinated  Debentures  against  the  Company  pursuant  to the  terms  of the
Indenture  (as  defined  herein).  However,  if  the  Trust's  failure  to  make
distributions  on the TECONS is a consequence  of the Company's  exercise of its
right  to  extend  the  interest  payment  period  for the  Junior  Subordinated
Debentures,  the  Property  Trustee will have no right to enforce the payment of
distributions  on the TECONS until an Event of Default (as defined herein) under
the Declaration (as defined herein) shall have occurred.

     The  Declaration  provides  that the  Company  shall  pay for all debts and
obligations  (other than with respect to the Trust Securities) and all costs and
expenses  of AES  Trust,  including  any taxes and all costs and  expenses  with
respect thereto, to which the Trust may become subject, except for United States
withholding  taxes.  No  assurance  can be given  that  the  Company  will  have
sufficient  resources  to enable it to pay such  debts,  obligations,  costs and
expenses on behalf of the Trust.


OPTION TO EXTEND INTEREST PAYMENT PERIOD; TAX IMPACT OF EXTENSION

     So long as the  Company  shall not be in default in the payment of interest
on the Junior  Subordinated  Debentures,  the  Company  has the right  under the
Indenture to defer payments of interest on the Junior Subordinated Debentures by
extending  the  interest  payment  period  from  time  to  time  on  the  Junior
Subordinated  Debentures  for an extension  period not exceeding 20  consecutive
quarterly  interest  periods (an "Extension  Period"),  during which no interest
shall be due and  payable.  In such an  event,  quarterly  distributions  on the
TECONS would not be made by the Trust during any such Extension  Period.  If the
Company  exercises the right to extend an interest  payment period,  the Company
may not during such  Extension  Period  declare or pay  dividends on, or redeem,
purchase, acquire or make a distribution or liquidation payment with respect to,
any of its common stock or preferred  stock;  provided that (i) the Company will
be permitted to pay accrued  dividends  upon the exchange or  redemption  of any
series of  preferred  stock of the  Company as may be  outstanding  from time to
time, in accordance with the terms of such stock and (ii) the foregoing will not
apply to stock  dividends  paid by the  Company.  Under the Amended and Restated
Certificate of Incorporation the Company is authorized to issue up to 50,000,000
shares of preferred  stock. As of September 30, 1997, no shares of the Company's
preferred stock were outstanding. The Company may from time to time offer shares
of its preferred stock to the public.



                                       22
<PAGE>


     Prior to the termination of any Extension  Period,  the Company may further
extend such Extension Period;  provided that such Extension Period together with
all such previous and further  extensions  thereof may not exceed 20 consecutive
quarterly interest periods. Upon the termination of any Extension Period and the
payment of all  amounts  then due,  the  Company  may  commence a new  Extension
Period,  subject to the above  requirements.  The Company may also prepay at any
time all or any portion of the  interest  accrued  during an  Extension  Period.
Consequently,  there  could be  multiple  Extension  Periods of varying  lengths
throughout  the term of the  Junior  Subordinated  Debentures,  not to exceed 20
consecutive quarters or to cause any extension beyond the maturity of the Junior
Subordinated Debentures.

     Because the Company has the right to extend the interest payment period for
an  Extension  Period of up to 20  consecutive  quarterly  interest  periods  on
various occasions,  the Junior Subordinated Debentures will be treated as issued
with "original issue discount" for United States federal income tax purposes. As
a result,  holders of TECONS will be required to include their pro rata share of
original  issue discount in gross income as it accrues for United States federal
income  tax  purposes  in advance of the  receipt of cash.  Generally,  all of a
securityholder's taxable interest income with respect to the Junior Subordinated
Debentures  will be  accounted  for as  "original  issue  discount"  and  actual
distributions  of stated  interest  will not be  separately  reported as taxable
income.


SPECIAL EVENT REDEMPTION OR DISTRIBUTION

     Upon  the  occurrence  and  during  the  continuation  of a  Tax  Event  or
Investment Company Event (each as defined herein),  which may occur at any time,
the Trust shall, unless the Junior  Subordinated  Debentures are redeemed in the
limited circumstances  described below, be dissolved with the result that Junior
Subordinated  Debentures  having  an  aggregate  principal  amount  equal to the
aggregate  stated   liquidation  amount  of,  and  bearing  accrued  and  unpaid
distributions on, the TECONS and Common Securities would be distributed on a Pro
Rata  Basis  (as  defined  herein)  to the  holders  of the  TECONS  and  Common
Securities in liquidation of such Trust.  In the case of a Tax Event, in certain
circumstances, the Company shall have the right to redeem at any time the Junior
Subordinated  Debentures  in whole or in part,  in which  event the  Trust  will
redeem  TECONS and Common  Securities  on a Pro Rata Basis to the same extent as
the Junior Subordinated Debentures are redeemed. There can be no assurance as to
the market prices for TECONS or the Junior Subordinated  Debentures which may be
distributed in exchange for TECONS if a dissolution and liquidation of the Trust
were to occur.  Accordingly,  the TECONS that an investor may  purchase,  or the
Junior Subordinated  Debentures that the investor may receive on dissolution and
liquidation of the Trust, may trade at a discount to the price that the investor
paid to  purchase  the  TECONS  offered  hereby.  Because  holders of TECONS may
receive Junior  Subordinated  Debentures  upon the occurrence of a Special Event
(as  defined  herein),  prospective  purchasers  of  TECONS  are also  making an
investment decision with regard to the Junior Subordinated Debentures and should
carefully  review  all  the  information   regarding  the  Junior   Subordinated
Debentures.

     There can be no assurance that future federal  legislation will not prevent
the Company from deducting interest on the Junior Subordinated Debentures.  This
would  constitute a Tax Event and could result in the distribution of any Junior
Subordinated  Debentures to holders of the TECONS or, in certain  circumstances,
the  redemption of such  securities by the Company and the  distribution  of the
resulting cash in redemption of the TECONS.

     "Tax Event" means that the Regular  Trustees (as defined herein) shall have
obtained  an  opinion  of  a  nationally  recognized   independent  tax  counsel
experienced in such matters (a "Dissolution  Tax Opinion") to the effect that on
or after October 23, 1997 as a result of (a) any amendment to, or change in, the
laws (or any  regulations  thereunder)  of the  United  States or any  political
subdivision  or taxing  authority  thereof or therein,  (b) any amendment to, or
change in, an  interpretation  or application of any such laws or regulations by
any  legislative  body,  court,  governmental  agency  or  regulatory  authority
(including the enactment of any  legislation and the publication of any judicial
decision or regulatory  determination),  (c) any interpretation or pronouncement
that  provides  for a position  with  respect to such laws or  regulations  that
differs from the theretofore generally accepted position or (d) any action 


                                       23
<PAGE>


taken by any  governmental  agency or regulatory  authority,  which amendment or
change is enacted,  promulgated,  issued or effective or which interpretation or
pronouncement  is issued or announced or which action is taken,  in each case on
or after October 23, 1997, there is more than an insubstantial risk that (i) the
Trust  is,  or will be within  90 days of the date  thereof,  subject  to United
States  federal  income tax with  respect to income  accrued or  received on the
Junior Subordinated Debentures,  (ii) the Trust is, or will be within 90 days of
the date  thereof,  subject  to more than a de  minimis  amount of other  taxes,
duties or other governmental charges or (iii) interest payable by the Company to
the Trust on the Junior Subordinated Debentures is not, or within 90 days of the
date thereof will not be,  deductible by the Company for United  States  federal
income tax purposes.

     "Investment  Company  Event"  means that the  Regular  Trustees  shall have
received an opinion of nationally recognized  independent counsel experienced in
practice under the Investment  Company Act of 1940, as amended (the "1940 Act"),
that as a result of the  occurrence of a change in law or regulation or a change
in  interpretation  or application of law or regulation by any legislative body,
court, governmental agency or regulatory authority (a "Change in 1940 Act Law"),
there is more than an insubstantial risk that the Trust is or will be considered
an "investment  company" which is required to be registered  under the 1940 Act,
which  Change in 1940 Act Law  becomes  effective  on or after  October 23, 1997
"Special Event" means a Tax Event or an Investment Company Event.


LIMITED VOTING RIGHTS

     Holders of TECONS will have limited voting rights,  but will not be able to
appoint,  remove or replace, or to increase or decrease the number of, Trustees,
which rights are vested exclusively in the Common Securities.


TRADING PRICES OF TECONS

     The TECONS may trade at a price  that does not fully  reflect  the value of
accrued but unpaid interest with respect to the underlying  Junior  Subordinated
Debentures.  A holder  who  disposes  of his  TECONS  between  record  dates for
payments of distributions thereon will be required to include accrued but unpaid
interest on the Junior  Subordinated  Debentures through the date of disposition
in income as ordinary  income,  and to add such amount to his adjusted tax basis
in his pro rata share of the underlying  Junior  Subordinated  Debentures deemed
disposed  of.  Accordingly,  such a holder will  recognize a capital loss to the
extent the selling  price (which may not fully  reflect the value of accrued but
unpaid interest) is less than the holders adjusted tax basis (which will include
accrued but unpaid  interest).  Subject to certain limited  exceptions,  capital
losses cannot be applied to offset  ordinary  income for United  States  federal
income tax purposes.


POTENTIAL MARKET VOLATILITY DURING EXTENSION PERIOD

     As described above, the Company has the right to extend an interest payment
period on the Junior Subordinated  Debentures from time to time for a period not
exceeding 20 consecutive  quarterly interest periods.  If the Company determines
to extend an interest payment period,  or if the Company  thereafter  extends an
Extension  Period or prepays  interest  accrued  during an  Extension  Period as
described  above,  the market price of the TECONS is likely to be  affected.  In
addition,  as a result of such  rights,  the market  price of the TECONS  (which
represent an undivided interest in Junior  Subordinated  Debentures) may be more
volatile than other  securities on which original issue discount accrues that do
not have such rights.  A holder that  disposes of its TECONS during an Extension
Period, therefore, may not receive the same return on its investment as a holder
that continues to hold its TECONS.


POSSIBLE PRICE VOLATILITY OF THE TECONS AND LACK OF PUBLIC MARKET

     There can be no assurance that an active trading market for the TECONS will
develop or be  sustained.  If such a market  were to develop,  the TECONS  could
trade at prices that may be higher or lower than their offering price  depending
upon many factors,  including prevailing interest rates, the Company's operating
results and the markets for  similar  securities.  Historically,  the market for
non-


                                       24
<PAGE>

investment grade debt has demonstrated  substantial  volatility in the prices of
securities  similar to the  TECONS.  There can be no  assurance  that the future
market for the TECONS will not be subject to similar volatility.  According,  no
assurance can given as to the liquidity of the TECONS.

     The  Initial  Purchasers,  other  than  Unterburg Harris, have informed the
Company  that  they  currently  intend  to make a market in the TECONS. However,
they  are not obligated to do so, and any such market making may be discontinued
at any time without notice. See "Plan of Distribution."

     For the  purpose  of  computing  the ratio of  earnings  to fixed  charges,
earnings  consist of income from continuing  operations  before income taxes and
minority interest, plus fixed charges, less capitalized interest, less excess of
earnings  over  dividends  of  less-than-fifty-percent-owned   companies.  Fixed
charges   consist  of  interest   (including   capitalized   interest)   on  all
indebtedness,  amortization  of debt  discount  and expense and that  portion of
rental expense which the Company  believes to be  representative  of an interest
factor. A statement setting forth the computation of the above ratios is on file
as an exhibit to the Registration Statement of which this Prospectus is a part.

     During the period from January 1, 1992 until  September 30, 1997, no shares
of  Preferred  Stock were  issued or  outstanding,  and during  that  period the
Company did not pay any Preferred Stock dividends.

     No cash  dividends  have been paid on AES Common  Stock since  December 22,
1993 in order  to  provide  capital  for the  Company's  equity  investments  in
projects.

     The Company's  ability to declare and pay  dividends  (and to make payments
with respect to the Junior  Subordinated  Debentures) is dependent,  among other
things, on the ability of its project  subsidiaries to declare and pay dividends
(and  otherwise  distribute  cash) to it, the  Company's  ability to service its
parent  company  debt and the  Company's  ability to meet  certain  criteria for
paying dividends under the Revolver and under certain outstanding indebtedness.


     The ability of the Company's  subsidiaries to declare and pay dividends and
otherwise  distribute  cash to the Company is subject to certain  limitations in
the project loans and other documents entered into by such project subsidiaries.
Such  limitations  permit the payment of dividends  out of current cash flow for
quarterly,  semi-annual  or annual  periods  only at the end of such periods and
only after  payment of principal and interest on project loans due at the end of
such periods.

     Cash  dividend  payments on AES Common Stock are limited under the Revolver
to a certain  percentage of cash flow. The indentures  relating to the Company's
existing senior  subordinated notes preclude the payment of cash dividends if at
the time of such payment or after giving effect  thereto an event of default (as
defined), or an event that, after the giving of notice or lapse of time or both,
would  become an event of default,  shall have  occurred and be  continuing,  if
certain  fixed  charge  coverage  ratios  are not met or if the  payment of such
dividends, together with other restricted payments, would exceed certain limits.

                                  AES TRUST II

     AES Trust II is a  statutory  business  trust under the  Delaware  Business
Trust Act (the "Business  Trust Act") formed pursuant to an amended and restated
declaration of trust dated as of October 29, 1997 (the "Declaration")  among the
Trustees and the Company and a certificate  of trust filed with the Secretary of
State of the State of Delaware, copies of which have been filed as an exhibit to
the  Registration  Statement of which this Prospectus is a part. The Declaration
is  qualified  under the Trust  Indenture  Act of 1939,  as amended  (the "Trust
Indenture Act").


TRUST SECURITIES

     Upon issuance of the TECONS, the holders thereof will own all of the issued
and outstanding  TECONS. The Company will acquire Common Securities in an amount
equal to at least 3% of the total capital of the Trust and will own, directly or
indirectly,  all of the  issued and  outstanding  Common  Securities.  The Trust
exists  for the  purpose  of (a)  issuing  its  Trust  Securities  for  cash and
investing the proceeds  thereof in an equivalent  amount of Junior  Subordinated
Debentures  and  (b)  engaging  in  such  other  activities  as  are  necessary,
convenient  and  incidental  thereto.  The  rights of the  holders  of the Trust
Securities,  including economic rights, rights to information and voting rights,
are as set  forth in the  Declaration,  the  Business  Trust  Act and the  Trust
Indenture  Act. The  Declaration  does not permit the incurrence by the Trust of
any  indebtedness  for borrowed money or the making of any investment other than
in the Junior  Subordinated  Debentures.  In the  Declaration,  the  Company has
agreed to pay for all debts and  obligations  (other  than with  respect  to the
Trust  Securities)  and all costs and expenses of the Trust,  including the fees
and expenses of the Trustees and any income taxes, duties and other governmental
charges, and all costs and expenses with respect thereto, to which the Trust may
become subject, except for United States withholding taxes.


POWERS AND DUTIES AND TRUSTEES

     The number of trustees  (the  "Trustees")  of AES Trust shall  initially be
five.  Three of such Trustees (the "Regular  Trustees") are  individuals who are
employees or officers of the Company.  The fourth such trustee will be The First
National Bank of Chicago,  which is unaffiliated with the Company and which will
serve as the property trustee (the "Property  Trustee") and act as the indenture
trustee for purposes of the Trust Indenture Act. The fifth such trustee is First
Chicago  Delaware Inc. that has its principal  place of business in the State of
Delaware (the "Delaware Trustee").  Pursuant to the Declaration,  legal title to
the Junior  Subordinated  Debentures  purchased by the Trust will be held by the
Property Trustee for the benefit of the holders of the Trust Securities, and the
Property  Trustee  will  have the  power to  exercise  all  rights,  powers  and
privileges  under  the  Indenture  with  respect  to  the  Junior   Subordinated
Debentures. In addition, the Property Trustee will maintain exclusive control of
a segregated  non-interest bearing bank account (the "Property Account") to hold
all payments in respect of the Junior Subordinated  Debentures  purchased by the
Trust for the benefit of the holders of Trust  Securities.  The Property Trustee
will promptly make  distributions  to the holders of the Trust Securities out of
funds from the Property Account. The Guarantee is separately qualified under the
Trust  Indenture  Act and will be held by The First  National  Bank of  Chicago,
acting in its  capacity as  indenture  trustee  with  respect  thereto,  for the
benefit  of the  holders  of the  TECONS.  As used in this  Prospectus  the term
"Property  Trustee" with respect to the Trust refers to The First  National Bank
of Chicago acting either in its capacity as a Trustee under the  Declaration and
the holder of legal title to the Junior Subordinated Debentures purchased by the
Trust or in its  capacity as  indenture  trustee  under,  and the holder of, the
Guarantee,  as the context may require.  The Company,  as the direct or indirect
owner of all of the  Common  Securities  of the Trust,  will have the  exclusive
right (subject to the terms of the  Declaration)  to appoint,  remove or replace
Trustees and to increase or decrease the number of Trustees,  provided  that the
number of Trustees shall be, except under certain  circumstances,  at least five
and the majority of Trustees  shall be Regular  Trustees.  The term of the Trust
set  forth  in  this  Prospectus  may  terminate  earlier  as  provided  in  the
Declaration.

     The duties and  obligations  of the Trustees of the Trust shall be governed
by the Declaration of the Trust,  the Business Trust Act and the Trust Indenture
Act.  Under its  Declaration,  the Trust shall not, and the Trustees shall cause
the Trust not to,  engage in any  activity  other  than in  connection  with the
purposes of 


                                       28
<PAGE>

the Trust or other than as required or authorized by the related Declaration. In
particular,  the Trust shall not and the  Trustees  shall cause the Trust not to
(a)  invest  any  proceeds  received  by  the  Trust  from  holding  the  Junior
Subordinated  Debentures  purchased by the Trust but shall  promptly  distribute
from the  Property  Account  all such  proceeds  to holders of Trust  Securities
pursuant to the terms of the related  Declaration  and of the Trust  Securities;
(b)  acquire  any  assets  other  than  as  expressly  provided  in the  related
Declaration; (c) possess Trust property for other than a Trust purpose; (d) make
any loans, other than loans represented by the Junior  Subordinated  Debentures;
(e)  possess any power or  otherwise  act in such a way as to vary the assets of
the Trust or the terms of its Trust Securities in any way whatsoever;  (f) issue
any  securities  or other  evidences of  beneficial  ownership of, or beneficial
interests  in,  the  Trust  other  than its  Trust  Securities;  (g)  incur  any
indebtedness  for borrowed money or (h)(i) direct the time,  method and place of
exercising any trust or power  conferred upon the Indenture  Trustee (as defined
under "Description of the Junior  Subordinated  Debentures") with respect to the
Junior  Subordinated  Debentures  deposited in the Trust as trust assets or upon
the Property  Trustee  with  respect to the TECONS,  (ii) waive any past default
that is waivable  under the  Indenture or the  Declaration,  (iii)  exercise any
right to  rescind  or annul any  declaration  that the  principal  of all of the
Junior Subordinated  Debentures  deposited in the Trust as trust assets shall be
due and payable or (iv) consent to any amendment, modification or termination of
the Indenture or such Junior  Subordinated  Debentures,  in each case where such
consent  shall be  required,  unless in the case of this clause (h) the Property
Trustee shall have  received an  unqualified  opinion of  nationally  recognized
independent tax counsel  recognized as expert in such matters to the effect that
such action will not cause the Trust to be classified  for United States federal
income tax purposes as an association  taxable as a corporation or a partnership
and that the Trust will  continue to be classified as a grantor trust for United
States federal income tax purposes.



BOOKS AND RECORDS

     The books and  records of AES Trust  will be  maintained  at the  principal
office of the Trust and will be open for inspection by a holder of TECONS or his
representative  for any purpose  reasonably related to his interest in AES Trust
during normal business hours.


THE PROPERTY TRUSTEE

     The  Property  Trustee,  for  the  benefit  of the  holders  of  the  Trust
Securities of the Trust,  is authorized  under the  Declaration  to exercise all
rights under the Indenture  with respect to the Junior  Subordinated  Debentures
deposited in AES Trust as trust  assets,  including  its rights as the holder of
such Junior Subordinated  Debentures to enforce the Company's  obligations under
such Junior Subordinated Debentures upon the occurrence of an Indenture Event of
Default.

     The  Property  Trustee  shall also be  authorized  to enforce the rights of
holders  of  TECONS  under  the  Guarantee.  If  the  Trust's  failure  to  make
distributions  on the TECONS is a consequence  of the Company's  exercise of any
right under the terms of the Junior  Subordinated  Debentures  deposited  in the
Trust as trust  assets to extend the  interest  payment  period for such  Junior
Subordinated Debentures,  the Property Trustee will have no right to enforce the
payment of  distributions  on such  TECONS  until an event of default  under the
Declaration  with  respect to the Trust  Securities  (an "Event of  Default"  or
"Declaration  Event of  Default")  shall  have  occurred.  Holders of at least a
majority  in  liquidation  amount of the TECONS  held by the Trust will have the
right to direct the Property  Trustee with respect to certain  matters under the
Declaration  and the  Guarantee.  If the Property  Trustee  fails to enforce its
rights  under the  Indenture  or fails to enforce the  Guarantee,  to the extent
permitted by applicable law, any holder of TECONS may, after a period of 30 days
has  elapsed  from such  holder's  written  request to the  Property  Trustee to
enforce such rights, institute a legal proceeding against the Company to enforce
such rights or the Guarantee, as the case may be. In addition, the holders of at
least 25% in aggregate  liquidation  preference of the outstanding  TECONS would
have the right to directly institute  proceedings for enforcement of payments to
such  holders of  principal  of, or  premium,  if any, or interest on the Junior
Subordinated  Debentures  having  a  principal  amount  equal  to the  aggregate
liquidation  preference  of the TECONS of such holders (a "Direct  Action").  In
connection with such Direct Action, the Company will be subrogated to the rights
of such holder of TECONS under the Declaration to the extent of any payment made
by the Company to such holders of TECONS in such Direct Action. 


                                       29
<PAGE>

Notwithstanding  the  foregoing,  if an Event of  Default  has  occurred  and is
continuing and such event is  attributable  to the failure of the Company to pay
interest or principal on the applicable series of Junior Subordinated Debentures
on the date such  interest or principal is otherwise  payable (or in the case of
redemption,  on the  redemption  date),  then a holder  of TECONS  may  directly
institute  a  proceeding  for  enforcement  of  payment  to such  holder  of the
principal  of or  interest  on the  applicable  series  of  Junior  Subordinated
Debentures having a principal amount equal to the aggregate  liquidation  amount
of the  TECONS  of such  holder  (a  "Holder  Direct  Action")  on or after  the
respective due date specified in the  applicable  series of Junior  Subordinated
Debentures.  In connection  with such Holder Direct Action,  the Company will be
subrogated to the rights of such holder of TECONS under the  Declaration  to the
extent  of any  payment  made by the  Company  to such  holder of TECONS in such
Holder Direct Action.




                           DESCRIPTION OF THE TECONS

     The TECONS were issued  pursuant to the terms of the  Declaration  which is
qualified  under  the Trust  Indenture  Act.  The  Property  Trustee,  The First
National Bank of Chicago,  but not the other Trustees of the Trust,  will act as
the indenture  trustee for purposes of the Trust Indenture Act. The terms of the
TECONS and the  Declaration  include those stated in the  Declaration  and those
made part of the  Declaration by the Trust  Indenture Act and the Business Trust
Act. The following  summarizes  the material  terms and provisions of the TECONS
and is qualified in its entirety by reference to, the Declaration,  the Business
Trust Act and the Trust Indenture Act.


GENERAL


     The Declaration  authorizes the Trust to issue the TECONS,  which represent
preferred  undivided  beneficial  interests in the assets of the Trust,  and the
Common Securities,  which represent common undivided beneficial interests in the
assets of the Trust.  All of the Common  Securities  will be owned,  directly or
indirectly, by the Company. The Common Securities and the TECONS rank pari passu
with each other and will have equivalent  terms except that (i) if a Declaration
Event of Default  occurs  and is  continuing,  the rights of the  holders of the
Common  Securities to payment in respect of periodic  Distributions and payments
upon liquidation,  redemption or otherwise are subordinated to the rights of the
holders of the TECONS and (ii) holders of Common  Securities  have the exclusive
right (subject to the terms of the  Declaration)  to appoint,  remove or replace
Trustees  and to increase or decrease the number of  Trustees.  The  Declaration
does not permit the issuance by the Trust of any  securities or other  evidences
of beneficial ownership of, or beneficial interests in, the Trust other than the
TECONS  and the  Common  Securities,  the  incurrence  of any  indebtedness  for
borrowed  money by the Trust or the making of any  investment  other than in the
Junior  Subordinated  Debentures.  Pursuant  to the  Declaration,  the  Property
Trustee will own and hold the Junior Subordinated Debentures as trust assets for
the benefit of the holders of the TECONS and the Common Securities.  The payment
of  Distributions  out of moneys held by the  Property  Trustee and  payments on
redemption  of the  TECONS or  liquidation  of the Trust are  guaranteed  by the
Company  on  a  subordinated   basis  as  and  to  the  extent  described  under
"Description of the Guarantee." The Property Trustee will hold the Guarantee for
the benefit of holders of the TECONS.  The Guarantee is a full and unconditional
guarantee  from the time of  issuance of the TECONS,  but the  Guarantee  covers
Distributions  and other  payments  on the TECONS only if and to the extent that
the Company has made a payment to the Property  Trustee of interest or principal
on the Junior  Subordinated  Debentures  deposited in the Trust as trust assets.
See "-- Voting Rights."


DISTRIBUTIONS


     Distributions  on the TECONS  will be fixed at an annual  rate of $2.75 per
TECONS.  Distributions  in arrears for more than one calendar  quarter will bear
interest  thereon  at the rate per annum of 5.50% (to the  extent  permitted  by
law), compounded quarterly. The term "Distributions" as used herein includes any
such interest  payable  unless  otherwise  stated.  The amount of  distributions
payable for any period will be computed on the basis of a 360-day year of twelve
30 day months. 


                                       30
<PAGE>


     Distributions  on the TECONS will be  cumulative,  will accrue from October
29, 1997 and, except as otherwise  described below, will be payable quarterly in
arrears on the last day of each quarter,  commencing  on December 31, 1997,  but
only if, and to the extent that, interest payments are made in respect of Junior
Subordinated Debentures held by the Property Trustee.

     So long as the  Company  shall not be in default in the payment of interest
on the Junior Subordinated Debentures, the Company has the right under the Trust
Indenture to defer payments of interest on the Junior Subordinated Debentures by
extending  the  interest  payment  period  from  time  to  time  on  the  Junior
Subordinated  Debentures  for a period not  exceeding 20  consecutive  quarterly
interest  periods  and,  as a  consequence,  the  Trust  would  defer  quarterly
Distributions on the TECONS (though such Distributions  would continue to accrue
with  interest  thereon  at the rate of 5.50% per annum,  compounded  quarterly)
during any such Extension Period; provided that no such period may extend beyond
the  stated  maturity  of the Junior  Subordinated  Debentures.  If the  Company
exercises the right to extend an interest  payment  period,  the Company may not
declare or pay dividends on, or redeem, purchase, acquire or make a distribution
or  liquidation  payment  with  respect to, any of its common stock or preferred
stock during such Extension  Period;  provided that the foregoing will not apply
to any stock dividend by the Company  payable in AES Common Stock.  Prior to the
termination  of any such Extension  Period,  the Company may further extend such
Extension  Period;  provided that such Extension  Period  together with all such
previous and further extensions thereof may not exceed 20 consecutive  quarterly
interest  periods.  Upon the termination of any Extension Period and the payment
of all  amounts  then due,  the  Company may  commence a new  Extension  Period,
subject to the above  requirements.  The Company may also prepay at any time all
or any portion of the interest accrued during an Extension Period. Consequently,
there could be multiple Extension Periods of varying lengths throughout the term
of the Junior Subordinated Debentures,  not to exceed 20 consecutive quarters or
to  cause  any  extension  beyond  the  maturity  of  the  Junior   Subordinated
Debentures.  See "Description of the Junior Subordinated Debentures -- Interest"
and "-- Option to Extend Interest Payment Period" and "Risk Factors -- Option to
Extend Interest  Payment Period;  Tax Impact of Extension."  Payments of accrued
distributions  will be payable to holders of TECONS as they  appear on the books
and records of the Trust on the first  record date after the end of an Extension
Period.

     Distributions on the TECONS must be paid on the dates payable to the extent
that the  Property  Trustee has cash on hand in the  Property  Account to permit
such payment.  The funds available for distribution to the holders of the TECONS
will be limited to payments  received by the Property  Trustee in respect of the
Junior Subordinated  Debentures that are deposited in the Trust as trust assets.
See "Description of the Junior Subordinated Debentures." If the Company does not
make  interest  payments on the Junior  Subordinated  Debentures,  the  Property
Trustee will not make distributions on the TECONS. Under the Declaration, if and
to the extent the Company does make interest payments on the Junior Subordinated
Debentures  deposited  in the Trust as trust  assets,  the  Property  Trustee is
obligated to make  distributions on the Trust Securities on a Pro Rata Basis. As
used in this  Prospectus  the term "Pro Rata Basis"  shall mean pro rata to each
holder of TECONS  according  to the  aggregate  liquidation  amount of the Trust
Securities of AES Trust held by the relevant holder in relation to the aggregate
liquidation  amount of all Trust Securities of AES Trust outstanding  unless, in
relation  to a payment,  a  Declaration  Event of Default  has  occurred  and is
continuing, in which case any funds available to make such payment shall be paid
first  to  each  holder  of the  TECONS  pro  rata  according  to the  aggregate
liquidation  amount of the TECONS held by the relevant holder in relation to the
aggregate  liquidation  amount of all the  TECONS  outstanding,  and only  after
satisfaction  of all amounts  owed to the  holders of TECONS,  to each holder of
Common  Securities of AES Trust pro rata according to the aggregate  liquidation
amount of all Common Securities outstanding.

     The payment of  distributions on the TECONS is guaranteed by the Company on
a subordinated  basis as and to the extent set forth under  "Description  of the
Guarantee." The Guarantee is a full and unconditional guarantee from the time of
issuance of the TECONS but the Guarantee covers distributions and other payments
on the TECONS  only if and to the extent  that the Company has made a payment to
the  Property  Trustee of  interest  or  principal  on the  Junior  Subordinated
Debentures  deposited in the Trust as trust assets.  Distributions on the TECONS
will be made to the  holders  thereof as they appear on the books and records of
the Trust on the relevant  record dates,  which, as long as the TECONS remain in
book-entry form, will be 


                                       31
<PAGE>

one Business Day (as defined herein) prior to the relevant  Distribution payment
date.  Distributions  payable on any TECONS that are not punctually  paid on any
Distribution  payment date as a result of the Company  having failed to make the
corresponding  interest  payment  on the  Junior  Subordinated  Debentures  will
forthwith  cease to be  payable  to the  person  in whose  name  such  TECONS is
registered on the relevant  record date,  and such defaulted  Distribution  will
instead be payable to the person in whose name such TECONS is  registered on the
special record date established by the Regular Trustees, which record date shall
correspond  to the special  record date or other  specified  date  determined in
accordance with the Indenture;  provided,  however, that Distributions shall not
be  considered  payable  on any  Distribution  payment  date  falling  within an
Extension  Period  unless  the  Company  has  elected  to make a full or partial
payment  of  interest  accrued  on the Junior  Subordinated  Debentures  on such
Distribution payment date.  Distributions on the TECONS will be paid through the
Property  Trustee  who will hold  amounts  received  in  respect  of the  Junior
Subordinated  Debentures in the Property  Account for the benefit of the holders
of the  Preferred  and Common  Securities.  Subject to any  applicable  laws and
regulations  and the  provisions of the  Declaration,  each such payment will be
made as described  under "--  Book-Entry;  Delivery and Form" and "-- The Global
TECONS"  below.  In the  event  that the  TECONS  do not  continue  to remain in
book-entry  form, the Regular  Trustees shall have the right to select  relevant
record  dates which shall be more than one  Business  Day prior to the  relevant
payment dates.  The Declaration  provides that the payment dates or record dates
for the TECONS  shall be the same as the payment  dates and record dates for the
Junior Subordinated Debentures. All distributions paid with respect to the Trust
Securities  shall be paid on a Pro Rata Basis to the  holders  thereof  entitled
thereto.  If any date on which distributions are to be made on the TECONS is not
a Business Day, then payment of the distribution to be made on such date will be
made on the next succeeding day that is a Business Day (and without any interest
or other payment in respect of any such delay) except that, if such Business Day
is in the next  succeeding  calendar  year,  such  payment  shall be made on the
immediately  preceding Business Day, in each case with the same force and effect
as if made on such date.  "Business Day" shall mean any day other than Saturday,
Sunday or any other day on which banking institutions in the City of New York in
the State of New York are permitted or required by any applicable law to close.


CONVERSION RIGHTS



General

     The TECONS will be  convertible  at any time prior to the close of business
on September 30, 2012 (or in the case of the TECONS called for redemption, prior
to the close of the business on the Business Day prior to the  Redemption  Date)
(the "Conversion  Expiration Date"), at the option of the holders thereof and in
the  manner  described  below,  into  shares of AES  Common  Stock at an initial
conversion rate of 0.8914 share of AES Common Stock for each TECONS  (equivalent
to a  conversion  price of $56.09  per share of AES Common  Stock (the  "Initial
Conversion  Price"),  subject to  adjustment as described  under "--  Conversion
Price   Adjustments  --  General"  and  "--  Conversion  Price   Adjustments  --
Fundamental  Change" below. If a TECONS is surrendered for conversion  after the
close of business on any regular record date for payment of a  Distribution  and
before the opening of business on the corresponding  Distribution  payment date,
then,   notwithstanding  such  conversion,  the  Distribution  payable  on  such
Distribution  payment  date will be paid in cash to the person in whose name the
TECONS is  registered  at the close of business on such record date,  and (other
than a TECONS or a portion of a TECONS  called for  redemption  on a  redemption
date  occurring  after  such  record  date and on or prior to such  Distribution
payment date) when so surrendered for conversion, the TECONS must be accompanied
by payment of an amount equal to the Distribution  payable on such  Distribution
payment date.

     The  terms of the  TECONS  provide  that a holder  of a TECONS  wishing  to
exercise its  conversion  right shall  surrender  such TECONS,  together with an
irrevocable conversion notice, to the Property Trustee, as conversion agent (the
"Conversion Agent"), which shall, on behalf of such holder, exchange such TECONS
for an  equivalent  amount of Junior  Subordinated  Debentures  and  immediately
convert such Junior Subordinated  Debentures into AES Common Stock.  Holders may
obtain copies of the required form of the conversion  notice from the Conversion
Agent.  So long as a  book-entry  system for the  TECONS is in effect,  however,
procedures  for  converting  the TECONS  into  shares of AES  Common  Stock will
differ,  as described under "Book-Entry -- Delivery and Form" and "-- The Global
TECONS." 


                                       32
<PAGE>


     No  fractional  shares of AES  Common  Stock  will be issued as a result of
conversion,  but in lieu thereof such fractional interest will be paid by AES in
cash based on the market  price of AES Common  Stock on the date such TECONS are
surrendered for conversion.


Conversion Price Adjustments -- General

     The Initial  Conversion Price is subject to adjustment  (under formulae set
forth in the Trust Indenture) in certain events, including:


        (i) the  issuance  of  AES Common Stock as a dividend or distribution on
   AES Common Stock;

        (ii) certain subdivisions and combinations of AES Common Stock;

       (iii) the issuance to all holders of AES Common  Stock of certain  rights
        or warrants to purchase  AES Common  Stock at less than the then current
        market price;

       (iv) the  distribution  to all holders of AES Common  Stock of (A) equity
        securities of the Company (other than AES Common  Stock),  (B) evidences
        of  indebtedness  of the  Company  and/or  (C) other  assets  (including
        securities,  but  excluding  (1) any rights or  warrants  referred to in
        clause  (iii)  above,  (2) any rights or warrants to acquire any capital
        stock  of any  entity  other  than the  Company,  (3) any  dividends  or
        distributions  in  connection  with  the  liquidation,   dissolution  or
        winding-up of the Company, (4) any dividends payable solely in cash that
        may from time to time be fixed by the Board of  Directors of the Company
        and (5) any dividends or distributions referred to in clause (i) above);

        (v)  distributions  to all holders of AES Common  Stock,  consisting  of
       cash,  excluding (a) any cash dividends on AES Common Stock to the extent
       that the  aggregate  cash  dividends per share of AES Common Stock in any
       consecutive  12-month  period do not exceed the greater of (x) the amount
       per share of AES Common  Stock of the cash  dividends  paid on AES Common
       Stock in the immediately  preceding  12-month period,  to the extent that
       such  dividends for the  immediately  preceding  12-month  period did not
       require an adjustment of the conversion price pursuant to this clause (v)
       (as  adjusted  to  reflect  subdivisions  or  combinations  of AES Common
       Stock), and (y) 15% of the average of the daily Closing Price (as defined
       in the Trust  Indenture)  of AES  Common  Stock  for the ten  consecutive
       Trading Days (as defined in the Trust Indenture) immediately prior to the
       date  of  declaration   of  such  dividend,   and  (b)  any  dividend  or
       distribution in connection with the  liquidation,  dissolution or winding
       up of the Company or a  redemption  of any rights  issued  under a rights
       agreement;  provided,  however, that no adjustment shall be made pursuant
       to this clause (v) if such  distribution  would  otherwise  constitute  a
       Fundamental  Change (as defined  below) and be  reflected  in a resulting
       adjustment described below; and

       (vi) payment in respect of a tender or  exchange  offer by the Company or
        any  subsidiary  of the Company for AES Common  Stock to the extent that
        the cash and value of any other  consideration  included in such payment
        per share of AES Common Stock exceed (by more than 10%, with any smaller
        excess being  disregarded in computing the adjustment  provided  hereby)
        the first  reported  sale  price per  share of AES  Common  Stock on the
        Trading Day next succeeding the Expiration Time (as defined in the Trust
        Indenture) for such tender or exchange offer.


     If any  adjustment  is required to be made as set forth in clause (v) above
as a result of a distribution  which is a dividend described in subclause (a) of
clause (v) above,  such adjustment  would be based upon the amount by which such
distribution  exceeds  the  amount  of the  dividend  permitted  to be  excluded
pursuant to such subclause (a) of clause (v). If an adjustment is required to be
made as set forth in clause (v) above as a result of a distribution which is not
such a  dividend,  such  adjustment  would be based upon the full amount of such
distribution.  If an  adjustment  is  required to be made as set forth in clause
(vi) above,  such adjustment  would be calculated based upon the amount by which
the aggregate consideration paid for the AES Common Stock acquired in the tender
or exchange offer exceeds 110% of the value of such shares based on the 


                                       33
<PAGE>

first reported sale price of AES Common Stock on the Trading Day next succeeding
the Expiration Time. In lieu of making such a conversion price adjustment in the
case of certain  dividends or  distributions,  the Company may provide that upon
the conversion of the TECONS the holder converting such TECONS will receive,  in
addition  to the AES Common  Stock to which such holder is  entitled,  the cash,
securities  or other  property  which such  holder  would have  received if such
holder  had,  immediately  prior  to  the  record  date  for  such  dividend  or
distribution, converted its TECONS into AES Common Stock.

     No  adjustment  in  the  conversion  price  will  be  required  unless  the
adjustment would require a change of at least 1% in the conversion price then in
effect; provided,  however, that any adjustment that would otherwise be required
to be made shall be carried  forward  and taken into  account in any  subsequent
adjustment.

     The Company from time to time may, to the extent  permitted by law,  reduce
the  conversion  price by any amount for any period of at least 20 Business Days
(as defined in the Trust  Indenture),  in which case the  Company  shall give at
least 15 days' notice of such reduction. In particular,  the Company may, at its
option,  make such reduction in the conversion  price,  in addition to those set
forth above,  as the Company deems advisable to avoid or diminish any income tax
to holders of AES Common Stock  resulting from any dividend or  distribution  of
stock (or  rights to  acquire  stock) or from any event  treated as such for tax
purposes or for any other  reasons.  See "Certain  Federal Tax  Consequences  --
Adjustment of Conversion Price."


Conversion Price Adjustments -- Fundamental Change

     In the event that the Company shall be a party to any transaction or series
of  transactions   constituting  a  Fundamental   Change,   including,   without
limitation,  (i) any  recapitalization  or  reclassification of AES Common Stock
(other than a change in par value or as a result of a subdivision or combination
of AES Common Stock);  (ii) any  consolidation  or merger of the Company with or
into another  corporation as a result of which holders of AES Common Stock shall
be entitled to receive  securities or other property or assets  (including cash)
with  respect to or in exchange  for AES Common Stock (other than a merger which
does not result in a reclassification,  conversion,  exchange or cancellation of
the  outstanding  AES  Common  Stock);  (iii)  any  sale or  transfer  of all or
substantially  all of the assets of the Company;  or (iv) any  compulsory  share
exchange, pursuant to any of which holders of AES Common Stock shall be entitled
to receive other securities,  cash or other property, then appropriate provision
shall be made so that the holder of each TECONS then outstanding  shall have the
right  thereafter  to convert such TECONS only into (x) if any such  transaction
does not constitute a Common Stock  Fundamental  Change (as defined below),  the
kind and amount of the  securities,  cash or other property that would have been
receivable upon such recapitalization,  reclassification, consolidation, merger,
sale,  transfer  or share  exchange  by a holder of the  number of shares of AES
Common Stock issuable upon conversion of such TECONS  immediately  prior to such
recapitalization,  reclassification,  consolidation,  merger,  sale, transfer or
share exchange, after, in the case of a Non-Stock Fundamental Change (as defined
below),  giving effect to any adjustment in the  conversion  price in accordance
with  clause (i) of the  following  paragraph,  and (y) if any such  transaction
constitutes  a Common Stock  Fundamental  Change,  shares of common stock of the
kind  received  by holders of AES Common  Stock as result of such  Common  Stock
Fundamental Change in an amount determined in accordance with clause (ii) of the
following paragraph.  The company formed by such consolidation or resulting from
such  merger or which  acquires  such  assets or which  acquires  the AES Common
Stock,  as the case may be, shall enter into a  supplemental  indenture with the
Indenture  Trustee (as defined  herein),  satisfactory  in form to the Indenture
Trustee and executed and delivered to the Indenture  Trustee,  the provisions of
which shall establish such right. Such supplemental  indenture shall provide for
adjustments  which,  for  events  subsequent  to  the  effective  date  of  such
supplemental  indenture  shall  be as  nearly  equivalent  as  practical  to the
relevant  adjustments  provided  for in the  preceding  paragraphs  and in  this
paragraph.

     Notwithstanding  any other  provision in the preceding  paragraphs,  if any
Fundamental  Change  occurs,  the  conversion  price in effect  will be adjusted
immediately after that Fundamental Change as follows: 

        (i) in the case of a Non-Stock  Fundamental Change, the conversion price
     per  share  of  AES  Common  Stock  immediately  following  such  Non-Stock
     Fundamental  Change will be the lower of (A) the conversion price in effect
     immediately prior to such Non-Stock Fundamental Change, but


                                       34
<PAGE>

     after giving effect to any other prior adjustments effected pursuant to the
     preceding  paragraphs,  and (B) the  result  obtained  by  multiplying  the
     greater of the Applicable  Price (as defined below) or the then  applicable
     Reference  Market  Price  (as  defined  below) by a  fraction  of which the
     numerator will be 100 and the  denominator of which will be an amount based
     on the date such  Non-Stock  Fundamental  Change  occurs.  For the 12-month
     period beginning October 29, 1997, the denominator will be 105.50,  and the
     denominator will decrease by 0.6875 during each successive 12-month period;
     provided, that the denominator shall in no event be less than 100.0.

       (ii) in the case of a Common Stock  Fundamental  Change,  the  conversion
     price per share of AES Common Stock immediately  following the Common Stock
     Fundamental Change will be the conversion price in effect immediately prior
     to the Common Stock  Fundamental  Change,  but after  giving  effect to any
     other prior  adjustments  effected  pursuant to the  preceding  paragraphs,
     multiplied by a fraction,  the  numerator of which is the  Purchaser  Stock
     Price (as defined  below) and the  denominator  of which is the  Applicable
     Price;  provided,  however, that in the event of a Common Stock Fundamental
     Change in which (A) 100% of the value of the  consideration  received  by a
     holder of AES Common  Stock  (subject  to certain  limited  exceptions)  is
     shares of common stock of the successor, acquiror or other third party (and
     cash, if any, paid with respect to any  fractional  interests in the shares
     of common stock resulting from the Common Stock Fundamental Change) and (B)
     all of the AES Common Stock (subject to certain limited  exceptions)  shall
     have been exchanged for,  converted into, or acquired for, shares of common
     stock (and cash,  if any,  with  respect to  fractional  interests)  of the
     successor, acquiror or other third party, the conversion price per share of
     AES Common Stock immediately  following the Common Stock Fundamental Change
     shall be the  conversion  price in effect  immediately  prior to the Common
     Stock Fundamental Change divided by the number of shares of common stock of
     the successor,  acquiror,  or other third party received by a holder of one
     share of AES  Common  Stock as a result  of the  Common  Stock  Fundamental
     Change.


     The foregoing  conversion price  adjustments are designed,  in "Fundamental
Change"  transactions  where all or substantially all of the AES Common Stock is
converted into securities,  cash, or property and not more than 50% of the value
received by the holders of AES Common Stock consists of stock listed or admitted
for listing subject to notice of issuance on a national  securities  exchange or
quoted on the  Nasdaq  National  Market of the  Nasdaq  Stock  Market,  Inc.  (a
"Non-Stock  Fundamental Change," as defined herein), to increase the securities,
cash or property into which each TECONS is convertible.


     In a Non-Stock  Fundamental  Change  transaction  where the  initial  value
received per share of AES Common Stock  (measured as described in the definition
of Applicable Price below) is lower than the then applicable conversion price of
the TECONS but greater than or equal to the  Reference  Market Price (as defined
herein),  the  conversion  price will be  adjusted as  described  above with the
effect that each TECONS will be convertible into securities, cash or property of
the same type  received by the holders of AES Common  Stock in such  transaction
but in an amount per TECONS equal to the amount  indicated as the denominator as
of the date of such transaction as set forth in clause (i) above with respect to
conversion prices for Non-Stock Fundamental Changes.


     In a Non-Stock  Fundamental  Change  transaction  where the  initial  value
received per share of AES Common Stock  (measured as described in the definition
of Applicable  Price below) is lower than both the conversion  price of a TECONS
and the  Reference  Market  Price,  the  conversion  price will be  adjusted  as
described  above  but  calculated  as  though  such  initial  value had been the
Reference Market Price.


     In a Fundamental  Change transaction where all or substantially all the AES
Common Stock is converted into  securities,  cash, or property and more than 50%
of the value  received  by the holders of AES Common  Stock  (subject to certain
limited  exceptions)  consists of listed or Nasdaq National Market traded common
stock (a "Common Stock  Fundamental  Change," as defined herein),  the foregoing
adjustments are designed to provide in effect that (a) where AES Common Stock is
converted partly into such common stock and partly into other securities,  cash,
or property,  each TECONS will be convertible  solely into a number of shares of
such common stock  determined so that the initial value of such shares (measured
as described in the definition of Purchaser  Stock Price below) equals the value
of the shares of AES Common 


                                       35
<PAGE>

Stock into which such TECONS was convertible  immediately before the transaction
(measured as aforesaid) and (b) where AES Common Stock is converted  solely into
such  common  stock,  each TECONS  will be  convertible  into the same number of
shares of such common  stock  receivable  by a holder of the number of shares of
AES Common Stock into which such TECONS was convertible  immediately before such
transaction.  In determining the amount and type of consideration  received by a
holder of AES Common Stock in the event of a Fundamental  Change,  consideration
received  by a holder of AES  Common  Stock  pursuant  to a  statutory  right of
appraisal will be disregarded.

     "Applicable Price" means (i) in the event of a Non-Stock Fundamental Change
in which the holders of AES Common Stock  receive only cash,  the amount of cash
receivable by a holder of one share of AES Common Stock and (ii) in the event of
any other Fundamental  Change,  the average of the Closing Prices (as defined in
the First  Supplemental  Indenture) for one share of AES Common Stock during the
ten Trading Days immediately  prior to the record date for the  determination of
the holders of AES Common Stock entitled to receive cash,  securities,  property
or other assets in connection  with such  Fundamental  Change or, if there is no
such record date, prior to the date on which the holders of the AES Common Stock
will have the right to receive such cash, securities, property or other assets.

     "Common Stock  Fundamental  Change" means any  Fundamental  Change in which
more than 50% of the value (as  determined in good faith by the Company's  Board
of  Directors)  of the  consideration  received  by holders of AES Common  Stock
(subject to certain limited exceptions) pursuant to such transaction consists of
shares of common stock that, for the ten  consecutive  Trading Days  immediately
prior to such  Fundamental  Change has been admitted for listing or admitted for
listing  subject to notice of  issuance  on a national  securities  exchange  or
quoted on the Nasdaq  National  Market,  provided,  however,  that a Fundamental
Change  will not be a Common  Stock  Fundamental  Change  unless  either (i) the
Company  continues to exist after the occurrence of such Fundamental  Change and
the  outstanding  TECONS  continue  to exist as  outstanding  TECONS or (ii) the
outstanding  TECONS continue to exist as TECONS and are convertible  into shares
of common stock of the successor to the Company.

     "Fundamental  Change" means the  occurrence of any  transaction or event or
series of transactions or events pursuant to which all or  substantially  all of
the  AES  Common  Stock  is  exchanged  for,  converted  into,  acquired  for or
constitutes  solely the right to receive  cash,  securities,  property  or other
assets  (whether  by means of an  exchange  offer,  liquidation,  tender  offer,
consolidation,  merger,  combination,   reclassification,   recapitalization  or
otherwise);  provided,  however,  in the case of a plan  involving more than one
such  transaction or event for purposes of adjustment of the  conversion  price,
such Fundamental  Change will be deemed to have occurred when  substantially all
of the AES Common Stock has been exchanged for,  converted into, or acquired for
or constitutes solely the right to receive cash,  securities,  property or other
assets but the adjustment shall be based upon the consideration that the holders
of AES Common Stock  received in the  transaction  or event as a result of which
more than 50% of the AES Common Stock shall have been exchanged  for,  converted
into,  or acquired  for, or shall  constitute  solely the right to receive  such
cash, securities, properties or other assets.

     "Non-Stock  Fundamental  Change"  means any Fundamental Change other than a
Common Stock Fundamental Change.

     "Purchaser Stock Price" means, with respect to any Common Stock Fundamental
Change, the average of the Closing Prices for one share of common stock received
by holders of AES Common Stock in such Common Stock  Fundamental  Change  during
the ten Trading Days immediately  prior to the record date for the determination
of the holders of AES Common  Stock  entitled  to receive  such shares of common
stock  or, if there is no such  record  date,  prior to the date upon  which the
holders of AES Common  Stock  shall  have the right to  receive  such  shares of
common stock.

     "Reference  Market  Price" will  initially  mean $29.92  (which  represents
662/3% of the last  reported  sale price per share of AES's  Common Stock on the
NYSE on October 23, 1997) and, in the event of any  adjustment to the conversion
price other than as a result of a Fundamental Change, the Reference Market Price
will also be adjusted  so that the ratio of the  Reference  Market  Price to the
conversion  price after giving effect to any adjustment  will always be the same
as the ratio of the initial  Reference  Market  Price to the Initial  Conversion
Price of the TECONS. 


                                       36
<PAGE>


     Conversions of the TECONS may be effected by delivering  them to the office
or  agency  of the  Company  maintained  for  such  purpose  in the  Borough  of
Manhattan, the City of New York.

     Conversion  price  adjustments  may,  in certain  circumstances,  result in
constructive distributions that could be taxable as dividends under the Internal
Revenue  Code of 1986,  as  amended  (the  "Code"),  to  holders of TECONS or to
holders of AES Common Stock issued upon conversion thereof. See "Certain Federal
Tax Consequences -- Adjustment of Conversion Price."

     No  adjustment  in  the  conversion  price  will  be  required  unless  the
adjustment would require a change of at least 1% in the conversion price then in
effect; provided,  however, that any adjustment that would otherwise be required
to be made shall be carried  forward  and taken into  account in any  subsequent
adjustment.


SPECIAL EVENT REDEMPTION OR DISTRIBUTION

     If,  at any time,  a Tax  Event or an  Investment  Company  Event  (each as
hereinafter  defined, and each a "Special Event") shall occur and be continuing,
the Trust shall, unless the Junior  Subordinated  Debentures are redeemed in the
limited circumstances  described below, be dissolved with the result that, after
satisfaction of creditors of the Trust, Junior  Subordinated  Debentures with an
aggregate  principal amount equal to the aggregate stated  liquidation amount of
the TECONS and the Common Securities would be distributed on a Pro Rata Basis to
the  holders  of the TECONS and the Common  Securities  in  liquidation  of such
holders' interests in the Trust, within 90 days following the occurrence of such
Special Event;  provided,  however,  that in the case of the occurrence of a Tax
Event, as a condition of such dissolution and distribution, the Regular Trustees
shall have received an opinion of nationally recognized  independent tax counsel
experienced in such matters (a "No Recognition Opinion"), which opinion may rely
on any  then  applicable  published  revenue  rulings  of the  Internal  Revenue
Service,  to the effect that the holders of the TECONS  will not  recognize  any
gain or loss for United States  Federal  income tax purposes as a result of such
dissolution and distribution of Junior Subordinated  Debentures;  and, provided,
further, that, if at the time there is available to the Trust the opportunity to
eliminate,  within  such  90 day  period,  the  Special  Event  by  taking  some
ministerial  action,  such as filing a form or making an  election,  or pursuing
some other similar reasonable measure,  which has no adverse effect on the Trust
or the Company or the holders of the TECONS,  the Trust will pursue such measure
in lieu of dissolution.  Furthermore,  if in the case of the occurrence of a Tax
Event,  (i) the Regular  Trustees  have received an opinion (a  "Redemption  Tax
Opinion") of nationally  recognized  independent tax counsel experienced in such
matters  that, as a result of a Tax Event,  there is more than an  insubstantial
risk that the Company  would be  precluded  from  deducting  the interest on the
Junior  Subordinated  Debentures  for United States  federal income tax purposes
even if the Junior  Subordinated  Debentures were  distributed to the holders of
TECONS and Common  Securities in liquidation  of such holders'  interests in the
Trust as described  above or (ii) the Regular  Trustees shall have been informed
by such tax counsel  that a No  Recognition  Opinion  cannot be delivered to the
Trust, the Company shall have the right,  upon not less than 30 nor more than 60
days notice,  to redeem the Junior  Subordinated  Debentures in whole or in part
for cash within 90 days following the occurrence of such Tax Event, and promptly
following  such  redemption  TECONS  and  Common  Securities  with an  aggregate
liquidation  amount  equal  to the  aggregate  principal  amount  of the  Junior
Subordinated  Debentures  so  redeemed  will be  redeemed  by the  Trust  at the
Redemption  Price on a Pro Rata Basis;  provided,  however,  that if at the time
there is available to the Company or the Regular  Trustees  the  opportunity  to
eliminate,  within such 90 day period,  the Tax Event by taking some ministerial
action,  such as filing a form or making an  election,  or  pursuing  some other
similar  reasonable  measure,  which has no  adverse  effect on the  Trust,  the
Company or the holders of the TECONS,  the Company  will pursue such  measure in
lieu of redemption and provided  further that the Company shall have no right to
redeem the Junior  Subordinated  Debentures while the Regular Trustees on behalf
of the Trust are pursuing any such  ministerial  action.  The Common  Securities
will be redeemed on a Pro Rata Basis with the TECONS, except that if an Event of
Default under the  Declaration  has occurred and is continuing,  the TECONS will
have a  priority  over the  Common  Securities  with  respect  to payment of the
Redemption Price.

     "Tax Event" means that the Regular  Trustees shall have obtained an opinion
of a nationally  recognized  independent tax counsel experienced in such matters
(a "Dissolution Tax Opinion") to the effect 


                                       37
<PAGE>


that on or after October 23, 1997 as a result of (a) any amendment to, or change
in,  the  laws (or any  regulations  thereunder)  of the  United  States  or any
political  subdivision or taxing authority thereof or therein, (b) any amendment
to,  or  change  in,  an  interpretation  or  application  of any  such  laws or
regulations by any legislative  body, court,  governmental  agency or regulatory
authority (including the enactment of any legislation and the publication of any
judicial  decision  or  regulatory  determination),  (c) any  interpretation  or
pronouncement  that  provides  for a  position  with  respect  to  such  laws or
regulations that differs from the theretofore generally accepted position or (d)
any action  taken by any  governmental  agency or  regulatory  authority,  which
amendment  or change is  enacted,  promulgated,  issued  or  effective  or which
interpretation or pronouncement is issued or announced or which action is taken,
in each case on or after October 23, 1997,  there is more than an  insubstantial
risk that (i) the  Trust  is,  or will be  within  90 days of the date  thereof,
subject to United States  Federal  income tax with respect to income  accrued or
received on the Junior  Subordinated  Debentures,  (ii) the Trust is, or will be
within 90 days of the date thereof,  subject to more than a de minimis amount of
other taxes,  duties or other governmental  charges or (iii) interest payable by
the Company to the Trust on the Junior Subordinated Debentures is not, or within
90 days of the date  thereof will not be,  deductible  by the Company for United
States federal income tax purposes.

     "Investment  Company  Event"  means that the  Regular  Trustees  shall have
received an opinion of nationally recognized  independent counsel experienced in
practice under the Investment  Company Act of 1940, as amended (the "1940 Act"),
that as a result of the  occurrence of a change in law or regulation or a change
in  interpretation  or application of law or regulation by any legislative body,
court, governmental agency or regulatory authority (a "Change in 1940 Act Law"),
there is more than an insubstantial risk that the Trust is or will be considered
an "investment  company" which is required to be registered  under the 1940 Act,
which Change in 1940 Act Law becomes effective on or after October 23, 1997.

     On the date fixed for any distribution of Junior  Subordinated  Debentures,
upon dissolution of the Trust, (i) the TECONS and the Common  Securities will no
longer be deemed to be outstanding,  (ii) the depositary or its nominee,  as the
record holder of the TECONS,  will receive a registered  global  certificate  or
certificates  representing  the Junior  Subordinated  Debentures to be delivered
upon such distribution,  and (iii) any certificates representing TECONS not held
by the depositary or its nominee will be deemed to represent Junior Subordinated
Debentures  having an aggregate  principal  amount equal to the aggregate stated
liquidation  amount of, with an interest rate identical to the distribution rate
of, and accrued and unpaid  interest  equal to accrued and unpaid  distributions
on, such TECONS,  until such  certificates  are  presented to the Company or its
agent for transfer or reissuance.

     There  can  be  no  assurance  as  to  the  market  price  for  the  Junior
Subordinated  Debentures  which may be  distributed  in exchange for TECONS if a
dissolution and liquidation of the Trust were to occur. Accordingly,  the Junior
Subordinated   Debentures  which  the  investor  may  subsequently   receive  on
dissolution and  liquidation of the Trust,  may trade at a discount to the price
of the TECONS exchanged.

MANDATORY REDEMPTION

     Upon the  repayment  of the  Junior  Subordinated  Debentures,  whether  at
maturity,  upon  redemption  or otherwise,  the proceeds from such  repayment or
payment will be promptly applied to redeem TECONS and Common  Securities  having
an aggregate  liquidation amount equal to the Junior Subordinated  Debentures so
repaid,  upon not less than 30 nor more than 60 days' notice,  at the Redemption
Price. The Common Securities will be entitled to be redeemed on a Pro Rata Basis
with the TECONS,  except that if an Event of Default under the  Declaration  has
occurred  and is  continuing,  the TECONS  will have a priority  over the Common
Securities  with  respect  to payment of the  Redemption  Price.  Subject to the
foregoing,  if fewer than all outstanding TECONS and Common Securities are to be
redeemed, the TECONS and Common Securities will be redeemed on a Pro Rata Basis.
In the event  fewer  than all  outstanding  TECONS  are to be  redeemed,  TECONS
registered  in the name of and held by DTC or its  nominee  will be  redeemed as
described under "-- Redemption Procedures" below.

REDEMPTION PROCEDURES

     The Trust may not redeem any  outstanding  TECONS  unless all  accrued  and
unpaid distributions have been paid on all TECONS for all quarterly distribution
periods terminating on or prior to the date of notice of redemption. 


                                       38
<PAGE>


     If the Trust  gives a notice of  redemption  in  respect  of TECONS  (which
notice will be  irrevocable)  then,  by 12:00 noon,  New York City time,  on the
redemption date and provided that the Company has paid to the Property Trustee a
sufficient amount of cash in connection with the related  redemption or maturity
of the Junior Subordinated  Debentures,  the Trust will irrevocably deposit with
the Depositary funds sufficient to pay the applicable  Redemption Price and will
give the Depositary irrevocable instructions and authority to pay the Redemption
Price to the  holders of the  TECONS.  See "-- The Global  TECONS." If notice of
redemption  shall  have been  given  and  funds  deposited  as  required,  then,
immediately  prior  to the  close  of  business  on the  date of  such  deposit,
distributions  will cease to accrue on the TECONS  called for  redemption,  such
TECONS shall no longer be deemed to be outstanding  and all rights of holders of
such TECONS so called for redemption will cease, except the right of the holders
of such TECONS to receive the  Redemption  Price,  but without  interest on such
Redemption  Price.  Neither  the  Trustees  nor the Trust  shall be  required to
register or cause to be registered the transfer of any TECONS which have been so
called  for  redemption.  If any date  fixed for  redemption  of TECONS is not a
Business Day, then payment of the Redemption  Price payable on such date will be
made on the next succeeding day that is a Business Day (and without any interest
or other payment in respect of any such delay) except that, if such Business Day
falls in the next calendar  year,  such payment will be made on the  immediately
preceding  Business  Day, in each case with the same force and effect as if made
on such  date  fixed  for  redemption.  If the  Company  fails to  repay  Junior
Subordinated  Debentures on maturity or on the date fixed for this redemption or
if payment of the Redemption  Price in respect of TECONS is improperly  withheld
or refused and not paid by the  Property  Trustee or by the Company  pursuant to
the Guarantee  described under "Description of the Guarantee,"  distributions on
such TECONS will continue to accrue,  from the original  redemption  date of the
TECONS to the date of  payment,  in which case the actual  payment  date will be
considered  the date  fixed for  redemption  for  purposes  of  calculating  the
Redemption Price.

     In the  event  that  fewer  than all of the  outstanding  TECONS  are to be
redeemed,  the TECONS will be redeemed as described  below under "-- Book-Entry;
Delivery and Form" and "-- The Global TECONS."

     If a partial  redemption of the TECONS would result in the delisting of the
TECONS by any national  securities  exchange or other  organization on which the
TECONS are then listed,  the Company  pursuant to the Indenture will only redeem
Junior  Subordinated  Debentures  in whole and, as a result,  the Trust may only
redeem the TECONS in whole.

     Subject to the foregoing and applicable law (including, without limitation,
United States Federal  securities  laws), the Company or any of its subsidiaries
may at any time and from time to time purchase  outstanding TECONS by tender, in
the open market or by private agreement.

LIQUIDATION DISTRIBUTION UPON DISSOLUTION

     In the event of any  voluntary  or  involuntary  dissolution,  liquidation,
winding-up  or  termination  of the Trust,  the holders of the TECONS and Common
Securities at the date of  dissolution,  winding-up or  termination of the Trust
will be entitled to receive on a Pro Rata Basis  solely out of the assets of the
Trust,  after  satisfaction  of  liabilities  of  creditors  (to the  extent not
satisfied by the Company as provided in the Declaration), an amount equal to the
aggregate  of the  stated  liquidation  amount  of $50 per Trust  Security  plus
accrued and unpaid  distributions  thereon to the date of payment  (such  amount
being  the  "Liquidation   Distribution"),   unless,  in  connection  with  such
dissolution,   liquidation,   winding-up  or  termination,  Junior  Subordinated
Debentures  in an  aggregate  principal  amount  equal to the  aggregate  stated
liquidation  amount of such Trust  Securities  and  bearing  accrued  and unpaid
interest  in an amount  equal to the accrued  and unpaid  distributions  on such
Trust Securities, shall be distributed on a Pro Rata Basis to the holders of the
TECONS and Common Securities in exchange therefor.

     If, upon any such  dissolution,  the Liquidation  Distribution  can be paid
only in part because the Trust has insufficient  assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the TECONS and the Common Securities shall be paid on a Pro Rata Basis.
The holders of the Common  Securities will be entitled to receive  distributions
upon any such  dissolution  on a Pro Rata Basis with the  holders of the TECONS,
except that if an Event of Default  under the  Declaration  has  occurred and is
continuing,  the TECONS shall have a priority  over the Common  Securities  with
respect to payment of the Liquidation Distribution.



                                       39
<PAGE>


     Pursuant to the Declaration,  the Trust shall terminate: (i) on November 1,
2031,  the  expiration  of the term of the  Trust;  (ii)  when all of the  Trust
Securities  shall have been called for redemption and the amounts  necessary for
redemption  thereof  shall have been paid to the holders of Trust  Securities in
accordance  with the terms of the  Trust  Securities;  or (iii)  when all of the
Junior  Subordinated  Debentures  shall have been  distributed to the holders of
Trust  Securities in exchange for all of the Trust Securities in accordance with
the terms of the Trust Securities.


NO MERGER, CONSOLIDATION OR AMALGAMATION OF THE TRUST

     The  Trust  may not  consolidate,  amalgamate,  merge  with or into,  or be
replaced  by, or convey,  transfer  or lease its  properties  and assets to, any
corporation or other entity.


DECLARATION EVENTS OF DEFAULT

     An event of default under the Indenture (an  "Indenture  Event of Default")
constitutes an Event of Default under the Declaration  with respect to the Trust
Securities;  provided that pursuant to the Declaration, the holder of the Common
Securities  will be deemed to have waived any such Event of Default with respect
to the Common  Securities until all Events of Default with respect to the TECONS
have been cured or waived.  Until all such Events of Default with respect to the
TECONS have been so cured or waived,  the Property  Trustee will be deemed to be
acting  solely on behalf of the holders of the  TECONS,  and only the holders of
the TECONS will have the right to direct the  Property  Trustee  with respect to
certain matters under the Declaration and consequently  under the Indenture.  In
the event that any Event of Default  with respect to the TECONS is waived by the
holders of the TECONS as  provided  in the  Declaration,  the  holders of Common
Securities  pursuant  to the  Declaration  have  agreed  that such  waiver  also
constitutes  a waiver  of such  Event of  Default  with  respect  to the  Common
Securities for all purposes under the Declaration  without any further act, vote
or consent of the holders of the Common Securities. See "Voting Rights" below.

     Upon the  occurrence  of an Event of Default,  the Property  Trustee as the
holder of all of the Junior  Subordinated  Debentures  will have the right under
the   Indenture  to  declare  the  principal  of  and  interest  on  the  Junior
Subordinated  Debentures to be  immediately  due and payable.  In addition,  the
Property  Trustee  will  have the  power to  exercise  all  rights,  powers  and
privileges  under the Indenture.  See  "Description  of the Junior  Subordinated
Debentures."


REGISTRATION RIGHTS

     In connection with the Original Offering,  the Trust and the Company agreed
with the Initial Purchasers,  for the benefit of the holders of the TECONS, that
the Company will use its reasonable best efforts, and at its cost, to file on or
before the 90th day  following  the date of  original  issuance  of the TECONS a
shelf registration  statement (the "Shelf Registration  Statement") with respect
to resales of the TECONS, the Guarantee,  the Junior Subordinated Debentures and
the  shares of AES Common  Stock  issuable  upon  conversion  (the  "Registrable
Securities") and to keep such registration statement effective until the earlier
of (i) the sale  pursuant to such  registration  statement or Rule 144 under the
Securities  Act of all the  Registrable  Securities and (ii) two years after the
date of the original issuance of the TECONS. Holders will be required to provide
certain information to the Company to be included in the registration  statement
in order to use the  prospectus  for resales.  The Company shall provide to each
holder  copies of the  prospectus,  notify each  holder  when such  registration
statement has become effective and take certain other actions as are required to
permit resales.  In the event that (i) the Shelf  Registration  Statement is not
declared  effective on or prior to the 180th day  following the date of original
issuance of the TECONS or (ii) if use of the Shelf  Registration  Statement  for
resales is suspended  for any time during the two-year  period after the date of
original  issuance  of the TECONS  for a period in excess of 30 days  during any
three-month  period or 60 days during any 12-month  period  (each,  a "permitted
black-out period"),  then additional  cumulative cash distributions (in addition
to amounts  otherwise  due on the TECONS) will accrue at an annual rate of $0.25
per TECONS for the first 90 days and  increasing to $0.50 per TECONS  thereafter
if clause (i) applies from April 28, 1998 until such 


                                       40
<PAGE>


registration  statement is declared  effective and if clause (ii) applies,  then
during  the  period,  other  than  any  permitted  black-out  period,  use is so
suspended.  The  Registration  Statement  of  which  this  Prospectus  is a part
constitutes the Shelf Registration Statement.


VOTING RIGHTS

     Except  as  provided  below,  under  "Modification  and  Amendment  of  the
Declaration" and "Description of the Guarantee" and as otherwise required by the
Business Trust Act, the Trust Indenture Act and the Declaration,  the holders of
the TECONS will have no voting rights.

     Subject to the requirements of this paragraph, the holders of a majority in
aggregate  liquidation  amount of the TECONS have the right (i) on behalf of all
holders  of  TECONS,  to waive  any past  default  that is  waivable  under  the
Declaration  and (ii) to direct  the time,  method and place of  conducting  any
proceeding for any remedy available to the Property  Trustee,  or exercising any
trust or power  conferred  upon the  Property  Trustee  under  the  Declaration,
including the right to direct the Property Trustee,  as the holder of the Junior
Subordinated Debentures,  to (A) direct the time, method and place of conducting
any  proceeding  for any remedy  available to the Indenture  Trustee (as defined
herein), or executing any trust or power conferred on the Indenture Trustee with
respect to the Junior Subordinated  Debentures,  (B) waive any past default that
is waivable  under Section 6.06 of the  Indenture,  or (C) exercise any right to
rescind or annul a declaration that the principal of all the Junior Subordinated
Debentures  shall be due and payable;  provided  that where a consent  under the
Indenture  would  require  the  consent of (a)  holders  of Junior  Subordinated
Debentures  representing  a  specified  percentage  greater  than a majority  in
principal  amount of the Junior  Subordinated  Debentures  or (b) each holder of
Junior Subordinated  Debentures affected thereby, no such consent shall be given
by the Property  Trustee without the prior consent of, in the case of clause (a)
above, holders of TECONS representing such specified percentage of the aggregate
liquidation  amount of the  TECONS  or, in the case of clause  (b)  above,  each
holder of all TECONS affected thereby. The Property Trustee shall not revoke any
action previously authorized or approved by a vote of the holders of TECONS. The
Property  Trustee  shall notify all holders of record of TECONS of any notice of
default  received  from  the  Indenture  Trustee  with  respect  to  the  Junior
Subordinated  Debentures.  Other than with respect to directing the time, method
and place of conducting any proceeding for any remedy  available to the Property
Trustee or the Indenture  Trustee as set forth above, the Property Trustee shall
be under no obligation to take any of the foregoing  actions at the direction of
the holders of the TECONS  unless the Property  Trustee  shall have  obtained an
opinion of nationally recognized independent tax counsel recognized as expert in
such  matters to the effect  that the Trust  will not be  classified  for United
States federal income tax purposes as an association taxable as a corporation or
a  partnership  on account of such action and will be treated as a grantor trust
for United States  federal  income tax purposes  following  such action.  If the
Property  Trustee fails to enforce its rights under the Declaration  (including,
without limitation,  its rights, powers and privileges as a holder of the Junior
Subordinated  Debentures under the Indenture),  any holder of TECONS may, to the
extent  permitted by applicable  law, after a period of 30 days has elapsed from
such holder's  written  request to the Property  Trustee to enforce such rights,
institute  a legal  proceeding  directly  against  the  Company to  enforce  the
Property  Trustee's  rights under the Declaration,  without first  instituting a
legal proceeding  against the Property Trustee or any other Person. In addition,
in case of an Event of Default which is attributed to the failure of the Company
to pay interest or principal on the Junior Subordinated  Debentures, a holder of
TECONS may directly  institute a proceeding  for  enforcement of payment to such
holder of the principal of, or interest on, the Junior  Subordinated  Debentures
having a  principal  amount  equal to the  aggregate  liquidation  amount of the
TECONS of such holder. See "-- Declaration Events of Default."

     A waiver of an Indenture  Event of Default by the  Property  Trustee at the
direction of holders of the TECONS will constitute a waiver of the corresponding
Event of Default under the Declaration in respect of the Trust Securities.

     In the event the  consent  of the  Property  Trustee  as the  holder of the
Junior  Subordinated  Debentures  is  required  under the Trust  Indenture  with
respect to any amendment,  modification or termination of the Trust Indenture or
the Junior Subordinated Debentures, the Property Trustee shall request the 


                                       41
<PAGE>

direction of the holders of the Trust Securities with respect to such amendment,
modification  or  termination  and shall vote with  respect  to such  amendment,
modification  or termination as directed by a majority in liquidation  amount of
the Trust Securities voting together as a single class; provided,  however, that
where any such amendment,  modification or termination under the Indenture would
require the consent of holders of Junior Subordinated  Debentures representing a
specified  percentage  greater than a majority in principal amount of the Junior
Subordinated Debentures,  the Property Trustee may only give such consent at the
direction  of the  holders  of  Trust  Securities  representing  such  specified
percentage of the aggregate  liquidation  amount of the Trust  Securities;  and,
provided,  further,  that the Property  Trustee  shall be under no obligation to
take any such action in  accordance  with the  directions  of the holders of the
Trust  Securities  unless  the  Property  Trustee  has  obtained  an  opinion of
nationally  recognized  independent  tax  counsel  recognized  as expert in such
matters to the effect that the Trust will not be  classified  for United  States
federal  income tax purposes as an  association  taxable as a  corporation  or a
partnership on account of such action and will be treated as a grantor trust for
United States Federal income tax purposes following such action.

     Any  required  approval or direction of holders of TECONS may be given at a
separate meeting of holders of TECONS convened for such purpose, at a meeting of
all of the  holders of Trust  Securities  or pursuant  to written  consent.  The
Regular  Trustees  will cause a notice of any meeting at which holders of TECONS
are entitled to vote,  or of any matter upon which action by written  consent of
such  holders is to be taken,  to be mailed to each  holder of record of TECONS.
Each such notice will  include a  statement  setting  forth (i) the date of such
meeting or the date by which such action is to be taken;  (ii) a description  of
any  resolution  proposed for adoption at such meeting on which such holders are
entitled  to vote or of such matter upon which  written  consent is sought;  and
(iii) instructions for the delivery of proxies or consents.

     No vote or consent of the holders of TECONS will be required  for the Trust
to redeem and cancel  TECONS or  distribute  Junior  Subordinated  Debentures in
accordance with the Declaration.

     Notwithstanding  that  holders  of TECONS are  entitled  to vote or consent
under any of the  circumstances  described above, any of the TECONS at such time
that  are  owned  by  the  Company  or by  any  entity  directly  or  indirectly
controlling or controlled by or under direct or indirect common control with the
Company shall not be entitled to vote or consent and shall, for purposes of such
vote or consent, be treated as if they were not outstanding.

     The procedures by which persons owning TECONS registered in the name of and
held by DTC or its nominee may exercise their voting rights are described  under
"-- The Global  TECONS"  below.  Holders  of the  TECONS  will have no rights to
increase or decrease  the number of Trustees or to appoint,  remove or replace a
Trustee,  which  rights  are  vested  exclusively  in the  holders of the Common
Securities.

MODIFICATION AND AMENDMENT OF THE DECLARATION

     The  Declaration  may be modified  and amended on approval of a majority of
the Regular Trustees,  provided, that, if any proposed modification or amendment
provides  for,  or the Regular  Trustees  otherwise  propose to effect,  (a) any
action that would adversely affect the powers,  preferences or special rights of
the  Trust  Securities,  whether  by way of  amendment  to  the  Declaration  or
otherwise, or (b) the dissolution,  winding-up or termination of the Trust other
than  pursuant  to the  terms  of  the  Declaration,  then  the  holders  of the
outstanding  Trust  Securities  as a  class  will  be  entitled  to vote on such
amendment  or proposal  and such  amendment  or proposal  shall not be effective
except with the  approval of at least a majority  in  liquidation  amount of the
Trust  Securities,  provided that if any amendment or proposal referred to above
would adversely affect only the TECONS or the Common  Securities,  then only the
affected  class will be entitled to vote on such  amendment or proposal and such
amendment  or proposal  shall not be  effective  except  with the  approval of a
majority in liquidation amount of such class of Securities.

     Notwithstanding the foregoing, (i) no amendment or modification may be made
to the Declaration  unless the Regular Trustees shall have obtained (a) either a
ruling from the Internal  Revenue  Service or a written  unqualified  opinion of
nationally recognized independent tax counsel experienced in such 


                                       42
<PAGE>

matters  to the  effect  that  such  amendment  will not  cause  the Trust to be
classified  for United  States  federal  income tax  purposes as an  association
taxable as a corporation or a partnership  and to the effect that the Trust will
continue to be treated as a grantor trust for purposes of United States  federal
income taxation and (b) a written unqualified  opinion of nationally  recognized
independent  counsel  experienced  in  such  matters  to the  effect  that  such
amendment  will not  cause  the  Trust to be an  "investment  company"  which is
required to be registered under the 1940 Act; (ii) certain specified  provisions
of the  Declaration may not be amended without the consent of all of the holders
of the Trust Securities;  (iii) no amendment which adversely affects the rights,
powers and privileges of the Property  Trustee shall be made without the consent
of the  Property  Trustee;  (iv) Article IV of the  Declaration  relating to the
obligation of the Company to purchase the Common  Securities  and to pay certain
obligations  and expenses of the Trust may not be amended without the consent of
the Company;  and (v) the rights of holders of Common Securities under Article V
of the  Declaration  to  increase  or  decrease  the number of, and to  appoint,
replace or remove,  Trustees  shall not be amended  without  the consent of each
holder of Common Securities.

     The Declaration further provides that it may be amended without the consent
of the holders of the Trust  Securities to (i) cure any ambiguity;  (ii) correct
or  supplement  any  provision  in the  Declaration  that  may be  defective  or
inconsistent  with any other provision of the  Declaration;  (iii) to add to the
covenants,  restrictions  or obligations of the Company;  and (iv) to conform to
changes in, or a change in  interpretation  or  application  of certain 1940 Act
requirements  by the Commission,  which amendment does not adversely  affect the
rights, preferences or privileges of the holders.


DEBTS AND OBLIGATIONS

     In the  Declaration,  the  Company  has  agreed  to pay for all  debts  and
obligations  (other than with respect to the Trust Securities) and all costs and
expenses of AES Trust,  including  the fees and expenses of its Trustees and any
taxes and all costs and expenses  with respect  thereto,  to which AES Trust may
become  subject,  except for United  States  withholding  taxes.  The  foregoing
obligations  of the Company under each  Declaration  are for the benefit of, and
shall be enforceable by, any person to whom any such debts, obligations,  costs,
expenses  and taxes are owed (a  "Creditor")  whether or not such  Creditor  has
received notice thereof.  Any such Creditor may enforce such  obligations of the
Company directly against the Company and the Company has irrevocably  waived any
right or remedy to require that any such  Creditor  take any action  against AES
Trust or any other person before proceeding against the Company. The Company has
agreed in each  Declaration  to execute  such  additional  agreements  as may be
necessary or desirable in order to give full effect to the foregoing.


BOOK-ENTRY; DELIVERY AND FORM


The following  describes the delivery and order of TECONS in connection with the
Originial  Offering and  transactions  in TECONS which are not being or have not
been resold under this Prospectus.

     The  certificates  representing  the  TECONS  have  been  issued  in  fully
registered  form.  TECONS  resold  in  offshore   transactions  in  reliance  on
Regulation S under the  Securities Act are  represented  by a single,  permanent
global TECONS in definitive,  fully  registered  form (the  "Regulation S Global
TECONS") deposited with the Property Trustee as custodian for DTC and registered
in the name of a nominee of DTC for the accounts of Euroclear and Cedel.

     TECONS  resold  in  reliance  on Rule  144A are  represented  by a  single,
permanent  global TECONS in definitive,  fully  registered form (the "Restricted
Global  TECONS")  deposited with the Trustee as custodian for DTC and registered
in the name of a nominee of DTC. The  Restricted  Global  TECONS (and any TECONS
issued in exchange therefor) are subject to certain restrictions on transfer set
forth therein and will bear a legend  regarding  such  restrictions.  Beneficial
interests in the  Restricted  Global TECONS may be  transferred  to a person who
takes delivery in the form of an interest in the Regulation S Global TECONS only
upon receipt by the Trustee of a written  certification  to the effect that such
transfer is being made in accordance with Regulation S under the Securities Act.
After the TECONS have been  registered and resold under the Securities  Act, all
certification requirements with respect to the TECONS will cease. 


                                       43
<PAGE>


Resales Under this Prospectus

     TECONS  resold under the  Registration  Statement of which this  Prospectus
forms a part  will be  represented  by a  single,  permanent  global  TECONS  in
definitive, fully registered form (the "Unrestricted Global TECONS" and with the
Regulation  S Global  TECONS  and the  Restricted  Global  TECONS,  the  "Global
TECONS"),  which is deposited with the Property Trustee as custodian for DTC and
registered in the name of a nominee of DTC.

     Upon each sale by a Selling  Holder of TECONS (or the  Junior  Subordinated
Debentures  or shares  of AES  Common  Stock  into  which  the  TECONS or Junior
Subordinated  Debentures,  as the case may be, may be converted) offered hereby,
such Selling  Holder will be required to deliver a notice (the "Notice") of such
sale to the  Property  Trustee and the  Company.  The Notice  will,  among other
things,  identify the sale as a sale pursuant to the  Registration  Statement of
which  this  Prospectus  forms a part,  certify  that  the  prospectus  delivery
requirements,  if any, of the  Securities Act have been  satisfied,  and certify
that the  Selling  Holder  and the  number of  TECONS  (or  Junior  Subordinated
Debentures or shares of AES Common Stock,  as the case may be) are identified in
the Prospectus in accordance with the applicable rules and regulations under the
Securities  Act.  A copy  of the  Notice  is  included  herein  in  Appendix  A.
Additional  copies may be  requested  form the  Company,  Attention:  William R.
Luraschi,  General  Counsel and  Secretary,  1001 North 19th Street,  Arlington,
Virginia 22209, telephone number (703) 522-1315.

     Upon  receipt by the Property  Trustee of the Notice  relating to a sale of
TECONS,  an  appropriate  adjustment  will be made to reflect a decrease  in the
principal  amount of the  Restricted  Global  TECONS or the  Regulation S Global
TECONS, as the case may be, or the cancellation of a TECONS in certificated form
upon the transfer thereof, and a corresponding  increase in the principal amount
of the Unrestricted Global TECONS.


Transfers between Global Securities

     Any beneficial  interest in one of the Global TECONS that is transferred to
a person  who takes  delivery  in the form of an  interest  in the other  Global
TECONS,  will, upon transfer,  cease to be an interest in such Global TECONS and
become an interest in the other Global TECONS, and, accordingly, will thereafter
be subject to all transfer restrictions, if any, and other procedures applicable
to  beneficial  interest in such other  Global  TECONS for as long as it remains
such interest.  Except in the limited circumstances  described under "The Global
TECONS," owners of beneficial interests in Global TECONS will not be entitled to
receive physical delivery of Certificated  TECONS (as defined below). The TECONS
are not issuable in bearer form.


Resales to Institutional Accredited Investors

     TECONS which are not resold under this Prospectus and which are transferred
to Institutional Accredited Investors who are not qualified institutional buyers
("Non-Global  Purchaser")  will be  issued  in  registered  form  ("Certificated
TECONS").  Upon the  transfer  of  Certificated  TECONS  initially  issued  to a
Non-Global Purchaser either to a qualified  institutional buyer or in accordance
with  Regulation S, such  Certificated  TECONS will,  unless the relevant Global
TECONS has  previously  been  exchanged  in whole for  Certificated  TECONS,  be
exchanged for an interest in a Global TECONS.


THE GLOBAL TECONS

     Upon the issuance of the Global TECONS,  DTC or its custodian have credited
or will credit, on its internal system,  the respective  principal amount of the
individual  beneficial  interests  represented  by  such  Global  TECONS  to the
accounts of persons who have accounts with such  depository.  Such accounts were
initially  designated  by or on behalf of the Initial  Purchasers.  Ownership of
beneficial  interests  in the Global  TECONS will be limited to persons who have
accounts  with  DTC  ("participants")  or  persons  who hold  interests  through
participants.  Ownership of  beneficial  interests in the Global  TECONS will be
shown on, and the  transfer of that  ownership  will be effected  only  through,
records  maintained  by,  DTC or its  nominee  (with  respect  to  interests  of
participants) and the records of participants (with respect to 


                                       44
<PAGE>


interest of persons other than participants).  Investors may hold their interest
in the Global  TECONS  directly  through  DTC if they are  participants  in such
system,  or indirectly  through  organizations  which are  participants  in such
system.

     Investors  may hold  their  interests  in the  Regulation  S Global  TECONS
directly  through Cedel or Euroclear,  if they are participants in such systems,
or  indirectly  through  organizations  that are  participants  in such systems.
Investors may also hold such interests through organizations other than Cedel or
Euroclear that are participants in the DTC system. Cedel and Euroclear will hold
interests  in the  Regulation  S Global  TECONS on behalf of their  participants
through DTC.

     So long as DTC, or its nominee,  is the  registered  owner or holder of the
Global TECONS,  DTC or such nominee,  as the case may be, will be considered the
sole owner or holder of the TECONS  represented  by such  Global  TECONS for all
purposes  under the Trust  Agreement and the TECONS.  No beneficial  owner of an
interest in the Global TECONS will be able to transfer  that interest  except in
accordance  with the  procedures  provided for under "Book  Entry;  Delivery and
Form," as well as DTC's  applicable  procedures  and,  if  applicable,  those of
Euroclear and Cedel.

     Payments of the  principal  of, and interest on, the Global  TECONS will be
made to DTC or its nominee, as the case may be, as the registered owner thereof.
None of the Company,  the Trust or any paying agent will have any responsibility
or  liability  for any aspect of the records  relating  to or  payments  made on
account  of  beneficial   ownership  interests  in  the  Global  TECONS  or  for
maintaining,  supervising or reviewing any records  relating to such  beneficial
ownership interests.

     The Company expects that DTC or its nominee, upon receipt of any payment of
principal or interest in respect of the Global TECONS will credit  participants'
accounts with payments in accounts  proportionate to their respective beneficial
interests in the  principal  amount of the Global TECONS as shown on the records
of DTC or its nominee. The Company also expects that payments by participants to
owners  of  beneficial   interests  in  the  Global  TECONS  held  through  such
participants will be governed by standing  instructions and customary practices,
as is now the case with securities held for the accounts of customers registered
in  the  name  of  nominees  for  such  customers.  Such  payments  will  be the
responsibility of such participants.

     Transfers between  participants in DTC will be effected in the ordinary way
in accordance  with DTC rules and will be settled in same-day funds. If a holder
requires physical delivery of a Certificated TECONS for any reason, including to
sell TECONS to persons in states which  require such  delivery of such TECONS or
to pledge such  TECONS,  such holder must  transfer  its  interest in the Global
TECONS in accordance  with the normal  procedures of DTC and the  procedures set
forth in "Book Entry;  Delivery and Form."  Transfers  between  participants  in
Euroclear  and Cedel will be effected in the  ordinary  way in  accordance  with
their respective rules and operating procedures.

     DTC has advised the Company  that it will take any action  permitted  to be
taken by a holder of TECONS  (including the  presentation of TECONS for exchange
as described  below) only at the direction of one or more  participants to whose
accounts the DTC  interests in the Global TECONS is credited and only in respect
of such portion of the aggregate  liquidation  amount of TECONS as to which such
participant or participants has or have given such direction.

     The  laws  of  some  jurisdictions   require  that  certain  purchasers  of
securities take physical  delivery of securities in definite form. Such laws may
impair the  ability to transfer  beneficial  interests  in the Global  TECONS as
represented by a global certificate.

     DTC is a limited-purpose trust company organized under the New York banking
Law, a "banking  organization" within the meaning of the New York Banking Law, a
member of the  Federal  Reserve  System,  a  "clearing  corporation"  within the
meaning  of the  New  York  Uniform  Commercial  Code  and a  "clearing  agency"
registered  pursuant to the provisions of Section 17A of the Securities Exchange
Act of 1934, as amended (the  "Exchange  Act").  DTC holds  securities  that its
participants  ("Participants")  deposit  with  DTC.  DTC  also  facilitates  the
settlement among Participants of securities transactions,  such as transfers and
pledges,  in deposited  securities  without electronic  computerized  book-entry
changes in  Participants'  accounts,  thereby  eliminating the need for physical
movement of securities certification. 


                                       45
<PAGE>

Direct  Participants  include  securities  brokers  and  dealers,  banks,  trust
companies,  clearing  corporations  and  certain  other  organizations  ("Direct
Participants").  DTC is owned by a number of its Direct  Participants and by the
Nasdaq  National  Market,  the American Stock  Exchange,  Inc., and the National
Association  of  Securities  Dealers,  Inc.  Access  to the DTC  System  is also
available to others,  such as  securities  brokers and dealers,  banks and trust
companies  that  clear  transaction  through or  maintain  a direct or  indirect
custodial  relationship with a Direct  Participant either directly or indirectly
("Indirect Participants").  The rules applicable to DTC and its Participants are
on file with the Securities and Exchange Commission.

     Conversion and redemption  notices shall be sent to DTC or its nominee.  If
less than all of the  TECONS of a Direct  Participant  are  being  converted  or
redeemed,  DTC or such  nominee  will reduce the amount of the  interest of each
Direct Participant in such TECONS in accordance with its normal procedures.

     Although voting with respect to the TECONS is limited, in those cases where
a vote is required, neither DTC nor its nominee will itself consent or vote with
respect to TECONS.  Under its usual procedures,  DTC would mail an Omnibus Proxy
to the Trust as soon as  possible  after the  record  date.  The  Omnibus  Proxy
assigns  consenting  or voting  rights  to those  Direct  Participants  to whose
accounts  the TECONS are  credited on the record date  (identified  in a listing
attached to the Omnibus Proxy).  AES and the Trust believe that the arrangements
among DTC, Direct and Indirect  Participants,  and Beneficial Owners will enable
the Beneficial  Owners to exercise rights  equivalent in substance to the rights
that can be  directly  exercised  by a holder of a  beneficial  interest  in the
Trust.

     Although DTC,  Euroclear and Cedel have agreed to the foregoing  procedures
in  order to  facilitate  transfers  of  interest  in the  Global  TECONS  among
participants  of DTC,  Euroclear  and  Cedel,  they are under no  obligation  to
perform or continue  to perform  such  procedures,  and such  procedures  may be
discontinued at any time. Neither the Company nor the Property Trustee will have
any  responsibility  for the  performance  by DTC,  Euroclear  or Cedel or their
respective   obligations   under  the  rules  and  procedures   governing  their
operations.  IF DTC discontinues being the Depositary and a successor Depositary
is not  obtained,  certificates  for the TECONS are  required  to be printed and
delivered.  Additionally,  the  Regular  Trustees  (with the consent of AES) may
decide to discontinue use of the system of book-entry  transfers through DTC (or
any  successor   Depositary)  with  respect  to  the  TECONS.   In  that  event,
certificates for the TECONS will be printed and delivered.

     The  information in this section  concerning  DTC,  Euroclear and Cedel and
DTC's  book-entry  system has been  obtained from sources that AES and the Trust
believe to be reliable,  but neither AES nor the Trust takes  responsibility for
the accuracy thereof.


CONVERSION AGENT, REGISTRAR, TRANSFER AGENT AND PAYING AGENT

     The Property  Trustee will act as  Conversion  Agent.  In addition,  in the
event the TECONS do not remain in book-entry only form, the following provisions
will apply:

     Payment of  distributions  and payments on redemption of the TECONS will be
payable,  the  transfer  of the TECONS will be  registrable,  and TECONS will be
exchangeable for TECONS of other  denominations of a like aggregate  liquidation
amount,  at the corporate trust office of the Property  Trustee in New York, New
York;  provided that payment of  distributions  may be made at the option of the
Regular  Trustees  on behalf of the Trust by check  mailed to the address of the
persons  entitled  thereto and that the payment on redemption of any TECONS will
be made only upon surrender of such TECONS to the Property Trustee.

     The First  National  Bank of Chicago or one of its  affiliates  will act as
registrar and transfer agent for the TECONS.  The First National Bank of Chicago
will also act as paying agent and, with the consent of the Regular Trustees, may
designate additional paying agents.

     Registration  of transfers of TECONS will be effected  without charge by or
on behalf of the Trust,  but upon payment (with the giving of such  indemnity as
the  Trust  or  the  Company  may  require)  in  respect  of any  tax  or  other
governmental charges that may be imposed in relation to it.



                                       46
<PAGE>


     The Trust will not be required to  register or cause to be  registered  the
transfer of TECONS after such TECONS have been called for redemption.


INFORMATION CONCERNING THE PROPERTY TRUSTEE

     The  Property  Trustee,  prior  to a  default  with  respect  to the  Trust
Securities, undertakes to perform only such duties as are specifically set forth
in the Declaration and, after default, shall exercise the same degree of care as
a prudent  individual  would  exercise in the conduct of his or her own affairs.
Subject  to such  provision,  the  Property  Trustee is under no  obligation  to
exercise any of the powers vested in it by the Declaration at the request of any
holder of TECONS, unless offered reasonable indemnity by such holder against the
costs,  expenses and liabilities which might be incurred  thereby.  The Property
Trustee  is not  required  to expend or risk its own  funds or  otherwise  incur
personal  financial  liability in the  performance of its duties if the Property
Trustee  reasonably  believes  that  repayment  or  adequate  indemnity  is  not
reasonably assured to it.

     The Company and certain of its  affiliates  maintain a deposit  account and
banking relationship with the Property Trustee.


GOVERNING LAW

     The  Declaration  and the TECONS are  governed by, and will be construed in
accordance with, the internal laws of the State of Delaware.


MISCELLANEOUS

     The Regular  Trustees  are  authorized  and directed to take such action as
they  deem  reasonable  in order  that the  Trust  will not be  deemed  to be an
"investment  company"  required to be registered  under the 1940 Act or that the
Trust will not be classified for United States federal income tax purposes as an
association  taxable as a corporation or a partnership  and will be treated as a
grantor trust for United States federal income tax purposes. In this connection,
the Regular Trustees are authorized to take any action,  not  inconsistent  with
applicable  law, the certificate of trust or the  Declaration,  that the Regular
Trustees  determine  in their  discretion  to be  reasonable  and  necessary  or
desirable for such  purposes,  as long as such action does not adversely  affect
the interests of holders of the Trust Securities.

     The  Company  and the  Regular  Trustees  on behalf  of the  Trust  will be
required to provide to the Property Trustee annually a certificate as to whether
or not the Company and the Trust,  respectively,  is in compliance  with all the
conditions and covenants under the Declaration.



                          DESCRIPTION OF THE GUARANTEE

     Set forth  below is a  summary  of  information  concerning  the  Guarantee
executed  and  delivered by the Company for the benefit of the holders from time
to time of TECONS.  The Guarantee has been separately  qualified under the Trust
Indenture Act and is held by The First  National Bank of Chicago,  acting in its
capacity as indenture  trustee with respect thereto,  for the benefit of holders
of the TECONS.  The terms of the  Guarantee are those set forth in the Guarantee
and  those  made  part  of such  Guarantee  by the  Trust  Indenture  Act.  This
description  summarizes  the material terms of the Guarantee and is qualified in
its entirety by reference to the Guarantee (a copy of which has been included as
an exhibit to the Registration  Statement of which this Prospectus Offering is a
part) and the Trust  Indenture Act.  Section and Article  references used herein
are references to the provisions of the Guarantee.


GENERAL

     Pursuant to the Guarantee, the Company will irrevocably and unconditionally
agree,  to the extent set forth  therein,  to pay in full, to the holders of the
TECONS,  the Guarantee  Payments (as defined  herein)  (without  duplication  of
amounts  theretofore  paid by AES  Trust),  to the extent not paid by AES Trust,
regardless of any defense,  right of set-off or counterclaim  that AES Trust may
have or assert.  The following  payments or distributions with respect to TECONS
to the extent not paid or made by AES 


                                       47
<PAGE>

Trust (the  "Guarantee  Payments"),  will be subject to the  Guarantee  (without
duplication):  (i) any  accrued  and unpaid  distributions  on  TECONS,  and the
redemption price,  including all accrued and unpaid distributions to the date of
redemption, with respect to any TECONS called for redemption by AES Trust but if
and only to the extent  that in each case the  Company has made a payment to the
Property Trustee of interest or principal on the Junior Subordinated  Debentures
deposited in AES Trust as trust assets and (ii) upon a voluntary or  involuntary
dissolution,  winding-up or  termination  of AES Trust (other than in connection
with the distribution of such Junior  Subordinated  Debentures to the holders of
TECONS or the redemption of all of the TECONS upon the maturity or redemption of
such Junior  Subordinated  Debentures)  the lesser of (a) the  aggregate  of the
liquidation amount and all accrued and unpaid distributions on the TECONS to the
date of payment, to the extent AES Trust has funds available therefor or (b) the
amount of assets of AES Trust remaining available for distribution to holders of
the TECONS in  liquidation  of AES Trust.  The  Company's  obligation  to make a
Guarantee  Payment may be satisfied by direct payment of the required amounts by
the Company to the holders of TECONS or by causing AES Trust to pay such amounts
to such holders.

     The Guarantee is a guarantee  from the time of issuance of the TECONS,  but
the Guarantee covers  distributions and other payments on the TECONS only if and
to the extent  that the Company  has made a payment to the  Property  Trustee of
interest or principal  on the Junior  Subordinated  Debentures  deposited in AES
Trust as trust  assets.  If the  Company  does not make  interest  or  principal
payments on the Junior Subordinated  Debentures  deposited in AES Trust as trust
assets,  the Property Trustee will not make  distributions of the TECONS and AES
Trust will not have funds available therefor.

     The Company's obligations under the Declaration,  the Guarantee issued with
respect to TECONS, the Junior Subordinated Debentures purchased by the Trust and
the Indenture in the aggregate will provide a full and  unconditional  guarantee
on a subordinated basis by the Company of payments due on the TECONS.



CERTAIN COVENANTS OF THE COMPANY

     In the Guarantee,  has covenanted that, so long as any TECONS issued by AES
Trust remain outstanding,  the Company will not (A) declare or pay any dividends
on, or redeem,  purchase,  acquire or make a distribution or liquidation payment
with  respect  to,  any of its  common  stock  or  preferred  stock  or make any
guarantee  payment  with  respect  thereto or (B) make any payment of  interest,
premium (if any) or principal on any debt securities issued by the Company which
rank pari passu with or junior to the Junior Subordinated Debentures, if at such
time (i) the Company shall be in default with respect to its Guarantee  Payments
or other payment obligations under the Guarantee, (ii) there shall have occurred
any  Declaration  Event of Default under the  Declaration  or (iii) in the event
that Junior  Subordinated  Debentures are issued to AES Trust in connection with
the  issuance of Trust  Securities,  the Company  shall have given notice of its
election to defer payments of interest on such Junior Subordinated Debentures by
extending  the  interest  payment  period as provided in the terms of the Junior
Subordinated   Debentures  and  such  period,  or  any  extension  thereof,   is
continuing:  provided that the foregoing will not apply to stock  dividends paid
by the Company in its Common  Stock.  In addition,  so long as any TECONS remain
outstanding,  the  Company  has agreed (i) to remain the sole direct or indirect
owner of all of the outstanding  Common Securities issued by AES Trust and shall
not cause or permit the Common Securities to be transferred except to the extent
permitted by the related  Declaration;  provided that any permitted successor of
the Company under the  Indenture  may succeed to the Company's  ownership of the
Common  Securities issued by the applicable AES Trust and (ii) to use reasonable
efforts to cause such AES Trust to continue to be treated as a grantor trust for
United  States  federal  income  tax  purposes   except  in  connection  with  a
distribution of Junior Subordinated Debentures.


AMENDMENTS AND ASSIGNMENT

     Except with respect to any changes that do not adversely  affect the rights
of holders of TECONS (in which case no consent will be required),  the Guarantee
may be amended  only with the prior  approval  of the holders of not less than a
majority in liquidation  amount of the  outstanding  TECONS issued by AES Trust.
All guarantees and agreements  contained in the Guarantee shall bind the succes-



                                       48
<PAGE>

sors,  assignees,  receivers,  trustees and  representatives  of the Company and
shall inure to the benefit of the holders of the TECONS then outstanding. Except
in connection with a consolidation, merger or sale involving the Company that is
permitted under the Indenture,  the Company may not assign its obligations under
the Guarantee.



TERMINATION OF THE GUARANTEE

     The  Guarantee  will  terminate and be of no further force and effect as to
the TECONS upon full payment of the redemption price of all the TECONS,  or upon
distribution of the Junior Subordinated  Debentures to the holders of the TECONS
in exchange for all of the TECONS,  or upon full payment of the amounts  payable
upon liquidation of AES Trust. Notwithstanding the foregoing, the Guarantee will
continue to be  effective or will be  reinstated,  as the case may be, if at any
time any holder of TECONS must restore payment of any sums paid under the TECONS
or the Guarantee.

     The  Company's  obligations  under  the  Guarantee  to make  the  Guarantee
Payments will  constitute  an unsecured  obligation of the Company and will rank
subordinate  and  junior in right of  payment  to all other  liabilities  of the
Company,  including the Junior Subordinated  Debentures,  except those made pari
passu or subordinate by their terms, and pari passu in right of payment with the
most senior  preferred stock issued,  from time to time, if any, by the Company.
The Company's  obligations  under the Guarantee  will rank pari passu with other
Preferred Securities Guarantees of the Company. Because the Company is a holding
company,  the Company's  obligations  under the  Guarantee are also  effectively
subordinated to all existing and future  liabilities,  including trade payables,
of the  Company's  subsidiaries,  except to the  extent  that the  Company  is a
creditor of the subsidiaries  recognized as such. The Declaration  provides that
each TECONS holder's  acceptance thereof agrees to the subordination  provisions
and other terms of the Guarantee.


STATUS OF THE GUARANTEE

     The Guarantee will  constitute a guarantee of payment and not of collection
(that is, the guaranteed party may institute a legal proceeding directly against
the  guarantor  to  enforce  its  rights  under  the  guarantee   without  first
instituting  a legal  proceeding  against  any  other  person  or  entity).  The
Guarantee  will be  deposited  with  The  First  National  Bank of  Chicago,  as
indenture  trustee,  to be held for the  benefit  of the  holders  of the TECONS
issued by AES Trust.  The First  National  Bank of  Chicago  shall  enforce  the
Guarantee on behalf of the holders of the TECONS. The holders of not less than a
majority in aggregate  liquidation amount of the TECONS have the right to direct
the time, method and place of conducting any proceeding for any remedy available
in respect of the  Guarantee,  including  the giving of  directions to The First
National Bank of Chicago. If The First National Bank of Chicago fails to enforce
the  Guarantee  as above  provided,  any holder of TECONS may  institute a legal
proceeding  directly  against  the  Company  to  enforce  its  rights  under the
Guarantee, without first instituting a legal proceeding against AES Trust or any
other person or entity. Notwithstanding the foregoing, if the Company has failed
to make a  guarantee  payment,  a holder  of TECONS  may  directly  institute  a
proceeding  against  the  Company  for  enforcement  of the  Guarantee  for such
payment.

MISCELLANEOUS

     The Company will be required to provide annually to The First National Bank
of Chicago a statement  as to the  performance  by the Company of certain of its
obligations under the Guarantee and as to any default in such  performance.  The
Company is required to file annually with The First  National Bank of Chicago an
officer's  certificate as to the Company's  compliance with all conditions under
the Guarantee.

     The First  National Bank of Chicago,  prior to the occurrence of a default,
undertakes  to perform  only such  duties as are  specifically  set forth in the
Guarantee and,  after default with respect to the Guarantee,  shall exercise the
same degree of care as a prudent individual would exercise in the conduct of his
or her own  affairs.  Subject  to such  provision,  The First  National  Bank of
Chicago is under no obligation to exercise any of the powers vested in it by the
Guarantee at the request of any holder of TECONS unless it is offered reasonable
indemnity  against the costs,  expenses and  liabilities  that might be incurred
thereby. 


                                       49

GOVERNING LAW

     The Guarantee is governed by, and will be construed in accordance with, the
laws of the State of New York.



               DESCRIPTION OF THE JUNIOR SUBORDINATED DEBENTURES


     Set forth below is a description of the Junior  Subordinated  Debentures in
which the Trust has  invested  the  proceeds  from the  issuance and sale of the
Trust Securities and which have been deposited in the Trust as trust assets. The
terms  of  the  Junior  Subordinated  Debentures  include  those  stated  in the
Indenture  dated as of March 1, 1997 between the Company and The First  National
Bank of Chicago,  as trustee (the "Indenture  Trustee"),  as supplemented by the
Second  Supplemental  Indenture dated as of October 29, 1997 between the Company
and the  Indenture  Trustee (as so  supplemented,  the "Trust  Indenture" or the
"Indenture")  copies of which have been included as exhibits to the Registration
Statement of which this Prospectus forms a part. The following  description does
not purport to be complete  and is qualified in its entirety by reference to the
Indenture and the Trust Indenture Act. Whenever particular provisions or defined
terms in the Indenture are referred to herein,  such provisions or defined terms
are incorporated by reference herein.


     The Indenture does not limit the aggregate principal amount of indebtedness
which may be issued thereunder and provides that junior subordinated  debentures
may be issued thereunder from time to time in one or more series  (collectively,
together   with  the   Junior   Subordinated   Debentures,   the   "Subordinated
Debentures").  The Junior Subordinated  Debentures  constitute a separate series
under the Indenture.


     Under  certain  circumstances   involving  the  dissolution  of  the  Trust
following the occurrence of a Special Event, Junior Subordinated  Debentures may
be  distributed  to the holders of the Trust  Securities in  liquidation  of the
Trust.   See   "Description  of  the  TECONS  --  Special  Event  Redemption  or
Distribution."


GENERAL


     The Junior Subordinated Debentures are unsecured,  subordinated obligations
of the Company,  limited in aggregate principal amount to an amount equal to the
sum of (i) the stated  liquidation  amount of the TECONS issued by the Trust and
(ii) the proceeds  received by the Trust upon issuance of the Common  Securities
to the Company  (which  proceeds  will be used to  purchase  an equal  principal
amount of  Junior  Subordinated  Debentures).  Since  the  Company  is a holding
company,  the Company's  rights and the rights of its  creditors,  including the
holders of Junior  Subordinated  Debentures to  participate in the assets of any
subsidiary upon the latter's liquidation or recapitalization  will be subject to
the prior claims of the  subsidiary's  creditors,  except to the extent that the
Company may itself be a creditor with recognized claims against the subsidiary.

     The entire  principal  amount of the Junior  Subordinated  Debentures  will
become due and payable,  together with any accrued and unpaid interest  thereon,
on September 30, 2012. The Junior Subordinated Debentures are not subject to any
sinking fund.

     If Junior  Subordinated  Debentures are distributed to holders of TECONS in
dissolution of the Trust, such Junior Subordinated  Debentures will initially be
issued as a Global  Security  (as defined  below).  As described  herein,  under
certain limited circumstances,  Junior Subordinated  Debentures may be issued in
certificated  form in  exchange  for a  Global  Security.  See  "Book-Entry  and
Settlement" below. In the event that Junior  Subordinated  Debentures are issued
in  certificated   form,  such  Junior   Subordinated   Debentures  will  be  in
denominations  of $50 and integral  multiples  thereof and may be transferred or
exchanged  at the  offices  described  below.  Payments  on Junior  Subordinated
Debentures  issued  as a  Global  Security  will be made  to  DTC,  a  successor
depositary  or, in the event that no  depositary  is used, to a paying agent for
the Junior Subordinated Debentures. 


                                       50
<PAGE>


     In the event that Junior Subordinated Debentures are issued in certificated
form,  payments of principal and interest  will be payable,  the transfer of the
Junior  Subordinated  Debentures  will be registrable,  and Junior  Subordinated
Debentures  will be  exchangeable  for Junior  Subordinated  Debentures of other
denominations  of a like  aggregate  principal  amount,  at the corporate  trust
office of the Indenture Trustee in New York, New York;  provided that payment of
interest may be made at the option of the Company by check mailed to the address
of the persons  entitled  thereto and that the payment of principal with respect
to any Junior  Subordinated  Debenture  will be made only upon surrender of such
Junior Subordinated Debenture to the Indenture Trustee.


SUBORDINATION

     The payment of principal  of,  premium,  if any, and interest on the Junior
Subordinated  Debentures  will, to the extent and in the manner set forth in the
Indenture,  be subordinated in right of payment to the prior payment in full, in
cash or cash equivalents, of all Senior and Subordinated Debt of the Company.

     Upon  any  payment  or   distribution  of  assets  to  creditors  upon  any
liquidation, dissolution, winding up, receivership,  reorganization,  assignment
for the  benefit of  creditors,  marshalling  of assets and  liabilities  or any
bankruptcy, insolvency or similar proceedings of the Company, the holders of all
Senior and  Subordinated  Debt will first be entitled to receive payment in full
of all  amounts  due or to become due  thereon  before the holders of the Junior
Subordinated  Debentures  will be  entitled to receive any payment in respect of
the  principal  of,  premium,  if any, or  interest  on the Junior  Subordinated
Debentures.

     No  payments  on account of  principal,  premium,  if any,  or  interest in
respect  of the Junior  Subordinated  Debentures  may be made by the  Company if
there  shall have  occurred  and be  continuing  a default in any  payment  with
respect to Senior and Subordinated  Debt or during certain periods when an event
of default  under  certain  Senior and  Subordinated  Debt  permits  the lenders
thereunder to accelerate the maturity of such Senior and  Subordinated  Debt. In
addition,  during the  continuance  of any other event of default  (other than a
payment  default)  with  respect  to  Designated  Senior and  Subordinated  Debt
pursuant to which the maturity  thereof may be  accelerated,  from and after the
date of receipt by the Trustee of written notice from holders of such Designated
Senior and  Subordinated  Debt or from an agent of such holders,  no payments on
account of  principal,  premium,  if any,  or  interest in respect of the Junior
Subordinated Debentures may be made by the Company during a period (the "Payment
Blockage  Period")  commencing on the date of delivery of such notice and ending
179 days thereafter  (unless such Payment Blockage Period shall be terminated by
written  notice to the Trustee  from the holders of such  Designated  Senior and
Subordinated Debt or from an agent of such holders, or such event of default has
been cured or waived or has ceased to exist).  Only one Payment  Blockage Period
may be commenced with respect to the Junior  Subordinated  Debentures during any
period  of 360  consecutive  days.  No event of  default  which  existed  or was
continuing on the date of the  commencement of any Payment  Blockage Period with
respect to the Designated  Senior and Subordinated  Debt initiating such Payment
Blockage  Period  shall  be or be made the  basis  for the  commencement  of any
subsequent  Payment Blockage Period by the holders of such Designated Senior and
Subordinated  Debt, unless such event of default shall have been cured or waived
for a period of not less than 90 consecutive days.

     By reason of such  subordination,  in the event of  insolvency,  funds that
would otherwise be payable to holders of Junior Subordinated  Debentures will be
paid to the holders of Senior and Subordinated Debt of the Company to the extent
necessary to pay such Debt in full,  and the Company may be unable to meet fully
its obligations with respect to the Junior Subordinated Debentures.

     "Debt"  is  defined  to mean,  with  respect  to any  person at any date of
determination  (without  duplication),  (i) all  indebtedness of such person for
borrowed  money,  (ii)  all  obligations  of such  person  evidenced  by  bonds,
debentures,  notes or other similar  instruments,  (iii) all obligations of such
person in respect of letters of credit or bankers'  acceptance  or other similar
instruments  (or  reimbursement  obligations  with  respect  thereto),  (iv) all
obligations  of such person to pay the  deferred  purchase  price of property or
services,  except trade  payables,  (v) all obligations of such person as lessee
under capitalized leases, (vi) all Debt of others secured by a lien on any asset
of such person, whether or not such Debt is 


                                       51
<PAGE>

assumed by such person; provided that, for purposes of determining the amount of
any Debt of the type described in this clause,  if recourse with respect to such
Debt is limited to such  asset,  the amount of such Debt shall be limited to the
lesser of the fair market value of such asset or the amount of such Debt,  (vii)
all  Debt of  others  guaranteed  by such  person  to the  extent  such  Debt is
guaranteed by such person,  (viii) all redeemable stock valued at the greater of
its  voluntary or  involuntary  liquidation  preference  plus accrued and unpaid
dividends and (ix) to the extent not otherwise included in this definition,  all
obligations  of  such  person  under  currency   agreements  and  interest  rate
agreements.

     "Designated Senior and Subordinated Debt" is defined to mean (i) Debt under
the Credit Agreement dated as of May 20, 1996 (the "Credit Agreement") among the
Company,  the Banks named on the signature pages thereof and the Morgan Guaranty
Trust Company of New York, as agent for the banks, as such Credit  Agreement has
been and may be amended, restated,  supplemented or otherwise modified from time
to time and (ii) Debt  constituting  Senior and Subordinated  Debt which, at the
time of its determination, (A) has an aggregate principal amount of at least $30
million and (B) is  specifically  designated in the instrument  evidencing  such
Senior and Subordinated Debt as "Designated Senior and Subordinated Debt" by the
Company.

     "Senior and  Subordinated  Debt" is defined to mean the  principal  of (and
premium,  if any) and  interest  on all  Debt of the  Company  whether  created,
incurred or assumed before, on or after the date of the Indenture; provided that
such Senior and  Subordinated  Debt shall not include (i) Debt of the Company to
any Affiliate,  (ii) Debt of the Company that, when incurred and without respect
to any  election  under  Section  1111(b) of Title 11,  U.S.  Code,  was without
recourse,  (iii)  any  other  Debt of the  Company  which  by the  terms  of the
instrument  creating or evidencing the same are  specifically  designated as not
being senior in right of payment to the Junior Subordinated  Debentures,  and in
particular  the Junior  Subordinated  Debentures  shall rank pari passu with all
other debt securities and guarantees  issued to any trust,  partnership or other
entity  affiliated with the Company which is a financing  vehicle of the Company
in connection with an issuance of preferred securities by such financing entity,
and (iv) redeemable stock of the Company.

OPTIONAL REDEMPTION

     Except as provided  below,  the Junior  Subordinated  Debentures may not be
redeemed  prior to September  30,  2000.  AES shall have the right to redeem the
Junior  Subordinated  Debentures,  in whole or in part, from time to time, on or
after September 30, 2000, upon not less than 30 nor more than 60 days notice, at
the following  prices  (expressed as percentages of the principal  amount of the
Junior  Subordinated  Debentures)  together  with  accrued and unpaid  interest,
including Compound Interest to, but excluding,  the redemption date, if redeemed
during the 12-month period beginning September 30:

</TABLE>



and 100% if redeemed on or after September 30, 2005.


     If the Junior Subordinated  Debentures are redeemed on any Interest Payment
Date (as defined below), accrued and unpaid interest shall be payable to holders
of record on the relevant record date.

     So long as the corresponding TECONS are outstanding,  the proceeds from the
redemption of any Junior Subordinated Debentures will be used to redeem TECONS.


     The  Company  will also have the right to redeem  the  Junior  Subordinated
Debentures at any time upon the occurrence of a Tax Event if certain  conditions
are  met  as  described  under  "Description  of the  TECONS  --  Special  Event
Redemption or Distribution."

     The Company may not redeem any Junior  Subordinated  Debentures  unless all
accrued and unpaid interest thereon,  including  Compounded  Interest,  has been
paid for all quarterly periods  terminating on or prior to the date of notice of
redemption.

     If  the  Company  gives  a  notice  of  redemption  in  respect  of  Junior
Subordinated Debentures (which notice will be irrevocable), then, by 12:00 noon,
New York City time, on the redemption date, the Company will deposit irrevocably
with the Indenture  Trustee funds  sufficient to pay the  applicable  Redemption
Price  and  will  give  irrevocable  instructions  and  authority  to  pay  such
Redemption Price to the holders of the Junior Subordinated Debentures. If notice
of redemption  shall have been given and funds deposited as required,  then upon
the  date  of  such  deposit,  interest  will  cease  to  accrue  on the  Junior
Subordinated   Debentures  called  for  redemption,   such  Junior  Subordinated
Debentures  will no longer be deemed to be outstanding and all rights of holders
of such Junior  Subordinated  Debentures  so called for  redemption  will cease,
except  the right of the  holders  of such  Junior  Subordinated  Debentures  to
receive the applicable Redemption Price, but without interest on such Redemption
Price. If any date fixed for redemption of Junior Subordinated Debentures is not
a Business Day, then payment of the  Redemption  Price payable on such date will
be made on the next  succeeding  day that is a  Business  Day (and  without  any
interest or other  payment in respect of any such delay)  except  that,  if such
Business Day falls in the next calendar  year,  such payment will be made on the
immediately  preceding Business Day, in each case with the same force and effect
as if made on such date fixed for redemption.  If the Company fails to repay the
Junior  Subordinated   Debentures  on  maturity  or  the  date  fixed  for  this
redemption,  or if  payment  of  the  Redemption  Price  in  respect  of  Junior
Subordinated  Debentures is  improperly  withheld or refused and not paid by the
Company,  interest  on such  Junior  Subordinated  Debentures  will  continue to
accrue,  from the original redemption date to the date of payment, in which case
the actual  payment date will be considered  the date fixed for  redemption  for
purposes of calculating  the applicable  Redemption  Price. If fewer than all of
the Junior Subordinated  Debentures are to be redeemed,  the Junior Subordinated
Debentures to be redeemed  shall be selected by lot or pro rata or in some other
equitable manner determined by the Indenture Trustee.

     In the event of any  redemption in part,  the Company shall not be required
to (i) issue,  register  the  transfer  of or exchange  any Junior  Subordinated
Debentures  during a period  beginning at the opening of business 15 days before
any selection for redemption of Junior Subordinated Debentures and ending 


                                       53
<PAGE>

at the close of business on the earliest  date on which the  relevant  notice of
redemption  is deemed to have been given to all  holders of Junior  Subordinated
Debentures  to be redeemed  and (ii)  register  the  transfer of or exchange any
Junior Subordinated Debentures so selected for redemption,  in whole or in part,
except  the  unredeemed  portion  of any Junior  Subordinated  Debentures  being
redeemed in part.



INTEREST

     The Junior Subordinated  Debentures will bear interest at the rate of 5.50%
per annum from October 29, 1997.  Interest will be payable  quarterly in arrears
on the last day of each calendar  quarter (each,  an "Interest  Payment  Date"),
commencing  on  December  31,  1997,  to the  person in whose  name such  Junior
Subordinated  Debenture is  registered,  subject to certain  exceptions,  at the
close of business on the Business Day next preceding such Interest Payment Date.
In the event (i) the TECONS shall not continue to remain in book-entry only form
or (ii) if  following  distribution  of the Junior  Subordinated  Debentures  to
holders of Trust  Securities  upon  dissolution of the Trust as described  under
"Description  of the  TECONS",  the  Junior  Subordinated  Debentures  shall not
continue to remain in book-entry only form, the relevant record date will be the
fifteenth day of the month in which the relevant  Interest  Payment Date occurs.
Interest  payable on any Junior  Subordinated  Debenture  that is not punctually
paid or duly provided for on any Interest  Payment Date will forthwith  cease to
be payable to the person in whose name such  Junior  Subordinated  Debenture  is
registered on the relevant record date, and such defaulted interest will instead
be payable to the person in whose name such  Junior  Subordinated  Debenture  is
registered  on the special  record date or other  specified  date  determined in
accordance  with the Indenture;  provided,  however,  that interest shall not be
considered payable by the Company on any Interest Payment Date falling within an
Extension  Period  unless  the  Company  has  elected  to make a full or partial
payment  of  interest  accrued  on the Junior  Subordinated  Debentures  on such
Interest Payment Date.

     The amount of interest payable for any period will be computed on the basis
of a 360-day  year of twelve 30 day  months.  If any date on which  interest  is
payable on the  Junior  Subordinated  Debentures  is not a  Business  Day,  then
payment of the interest payable on such date will be made on the next succeeding
day that is a Business Day (and without any interest or other payment in respect
of any such delay),  except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately  preceding Business
Day, in each case with the same force and effect as if made on such date.


OPTION TO EXTEND INTEREST PAYMENT PERIOD

     So long as the  Company  shall not be in default in the payment of interest
on the  Junior  Subordinated  Debentures,  the  Company  shall have the right to
extend the interest  payment period from time to time for a period not exceeding
20 consecutive quarters.  The Company has no current intention of exercising its
right to extend an interest payment period. No interest shall be due and payable
during an  Extension  Period,  except at the end thereof.  During any  Extension
Period,  the  Company  shall not  declare  or pay any  dividends  on, or redeem,
purchase, acquire or make a distribution or liquidation payment with respect to,
any of its common stock or preferred  stock or make any guarantee  payments with
respect  thereto;  provided that the foregoing will not apply to stock dividends
payable in AES Common Stock paid by the Company. Prior to the termination of any
such  Extension  Period,  the Company may further  extend the  interest  payment
period;  provided that such Extension Period together with all such previous and
further  extensions  thereof  may not exceed 20  consecutive  quarters or extend
beyond the  maturity  of the Junior  Subordinated  Debentures.  On the  Interest
Payment Date  occurring at the end of each Extension  Period,  the Company shall
pay to the  holders of Junior  Subordinated  Debentures  of record on the record
date for such Interest Payment Date (regardless of who the holders of record may
have been on other  dates  during the  Extension  Period) all accrued and unpaid
interest on the Junior Subordinated  Debentures,  together with interest thereon
at the rate  specified  for the  Junior  Subordinated  Debentures  to the extent
permitted by applicable law, compounded  quarterly.  Upon the termination of any
Extension  Period and the  payment of all  amounts  then due,  the  Company  may
commence a new Extension Period, subject to the above requirements.  The Company
may also prepay at any time all or any portion of the interest accrued during an
Extension Period. Consequently, there 


                                       54
<PAGE>

could be multiple  Extension  Periods of varying lengths  throughout the term of
the  Junior  Subordinated  Debentures,  not to exceed 20  consecutive  quarters;
provided,  that no such  period may extend  beyond  the stated  maturity  of the
Junior  Subordinated  Debentures.  The failure by the  Company to make  interest
payments  during an Extension  Period would not constitute a default or an event
of  default  under  the  Indenture  or  the  Company's   currently   outstanding
indebtedness.

     If the Property Trustee shall be the sole holder of the Junior Subordinated
Debentures,  the Company shall give the Property Trustee notice of its selection
of such  Extension  Period one Business Day prior to the earlier of (i) the date
the  distributions  on the  TECONS  are  payable  or (ii) the date the  Trust is
required  to  give  notice  to the  NYSE  or  other  applicable  self-regulatory
organization  or to holders  of the  TECONS of the record  date or the date such
distribution is payable.  The Trust shall give notice of the Company's selection
of such Extension Period to the holders of the TECONS.

     If Junior Subordinated Debentures have been distributed to holders of Trust
Securities,  the  Company  shall give the  holders  of the  Junior  Subordinated
Debentures  notice of its selection of such  Extension  Period ten Business Days
prior to the earlier of (i) the next  succeeding  Interest  Payment Date or (ii)
the date the  Company  is  required  to give  notice to the NYSE (if the  Junior
Subordinated   Debentures   are  then  listed   thereon)  or  other   applicable
self-regulatory organization or to holders of the Junior Subordinated Debentures
of the record or payment date of such related interest payment.


ADDITIONAL INTEREST

     If at any time  the  Trust  shall be  required  to pay any  taxes,  duties,
assessments or governmental  charges of whatever nature (other than  withholding
taxes)  imposed by the U.S.,  or any other taxing  authority,  then, in any such
case, AES will pay as additional interest ("Additional  Interest") on the Junior
Subordinated Debentures such additional amounts as shall be required so that the
net amounts  received  and  retained  by the Trust after  paying any such taxes,
duties,  assessments or other governmental  charges will be equal to the amounts
the Trust would have received had no such taxes,  duties,  assessments  or other
governmental charges been imposed.


CONVERSION OF THE JUNIOR SUBORDINATED DEBENTURES

     The Junior Subordinated Debentures are convertible into AES Common Stock at
the  option of the  holders of the Junior  Subordinated  Debentures  at any time
prior to the close of business on September  30, 2012 (or, in the case of Junior
Subordinated  Debentures  called for  redemption,  the close of  business on the
Business  Day prior to the  Redemption  Date) at the  Initial  Conversion  Price
subject to the conversion price adjustments  described under "Description of the
TECONS --  Conversion  Rights."  The  Trust has  agreed  not to  convert  Junior
Subordinated  Debentures  held by it except  pursuant to a notice of  conversion
delivered to the  Conversion  Agent by a holder of TECONS.  Upon  surrender of a
TECONS to the Conversion Agent for conversion,  the Trust will distribute Junior
Subordinated  Debentures to the Conversion  Agent on behalf of the holder of the
TECONS so  converted,  whereupon the  Conversion  Agent will convert such Junior
Subordinated  Debentures  to AES Common  Stock on behalf of such  holder.  AES's
delivery  to the  holders of the Junior  Subordinated  Debentures  (through  the
Conversion  Agent) of the fixed  number of shares of AES Common Stock into which
the Junior  Subordinated  Debentures  are  convertible  (together  with the cash
payment,  if any, in lieu of  fractional  shares)  will be deemed to satisfy the
obligation  of  AES to pay  the  principal  amount  of the  Junior  Subordinated
Debentures  so  converted,   and  the  accrued  and  unpaid   interest   thereon
attributable to the period from the last date to which interest has been paid or
duly provided for; provided,  however, that if any Junior Subordinated Debenture
is converted after a record date for payment of interest,  the interest  payable
on the related  Interest  Payment Date with respect to such Junior  Subordinated
Debenture shall be paid to the Trust (which will distribute such interest to the
converting  holder) or other holder of Junior  Subordinated  Debentures,  as the
case may be, despite such conversion.

COMPOUNDED INTEREST

     Payments of Compounded Interest on the Junior Subordinated  Debentures held
by the Trust will make funds available to pay any interest on  distributions  in
arrears in respect of the TECONS pursuant to the terms thereof.

CERTAIN   COVENANTS  OF  THE  COMPANY  APPLICABLE  TO  THE  JUNIOR  SUBORDINATED
DEBENTURES


     If Junior  Subordinated  Debentures  are issued to AES Trust in  connection
with the issuance of Trust Securities by AES Trust, the Company will covenant in
the  Indenture  that,  so  long  as  the  TECONS  issued  by  AES  Trust  remain
outstanding,  the Company will not declare or pay any  dividends  on, or redeem,
purchase, acquire or make a distribution or liquidation payment with respect to,
any of its common stock or preferred  stock or make any  guarantee  payment with
respect to, any of its common  stock or  preferred  stock or make any  guarantee
payment with respect thereto if at such time (i) the Company shall be in default
with respect to its Guarantee  Payments or other payment  obligations  under the
Guarantee,  (ii) there shall have occurred any  Indenture  Event of Default with
respect to the Junior Subordinated  Debentures or (iii) in the event that Junior
Subordinated  Debentures are issued to AES Trust in connection with the issuance
of Trust  Securities  by AES Trust,  the Company  shall have given notice of its
election to defer payments of interest on such Junior Subordinated Debentures by
extending  the interest  payment  period as provided in the terms of such Junior
Subordinated   Debentures  and  such  period,  or  any  extension  thereof,   is
continuing;  provided  that (x) the  Company  will be  permitted  to pay accrued
dividends  (and cash in lieu of  fractional  shares) upon the  conversion of any
preferred stock of the Company as may be outstanding  from time to time, in each
case in accordance  with the terms of such stock and (y) the foregoing  will not
apply to any  stock  dividends  paid by the  Company.  In  addition,  if  Junior
Subordinated  Debentures are issued to AES Trust in connection with the issuance
of Trust Securities by AES Trust, for so long as TECONS remain outstanding,  the
Company has agreed (i) to remain the sole direct or indirect owner of all of the
outstanding Common Securities issued by AES Trust and not to cause or permit the
Common  Securities  to be  transferred  except to the  extent  permitted  by the
Declaration;  provided  that any  permitted  successor of the Company  under the
Indenture may succeed to the Company's ownership of the Common Securities issued
by AES Trust,  (ii) to comply fully with all of its  obligations  and agreements
contained  in the  related  Declaration  and (iii) not to take any action  which
would  cause AES Trust to cease to be  treated  as a  grantor  trust for  United
States federal income tax purposes,  except in connection with a distribution of
Junior Subordinated Debentures.


INDENTURE EVENTS OF DEFAULT


     The  Indenture  provides  that any one or more of the  following  described
events, which has occurred and is continuing, constitutes an "Indenture Event of
Default" with respect to each series of Junior Subordinated Debentures:



       (a)  failure  for 30  days to pay  interest  on the  Junior  Subordinated
            Debentures of such series when due;  provided that a valid extension
            of the interest payment period by the Company shall not constitute a
            default in the payment of interest for this purpose;


       (b)  failure  to pay  principal  of or  premium,  if any,  on the  Junior
            Subordinated Debentures of such series when due whether at maturity,
            upon redemption, by declaration or otherwise;


       (c) failure to observe or perform  any other  covenant  contained  in the
           Indenture  with  respect to such  series  for 90 days  after  written
           notice to the Company from the Indenture Trustee or the holders of at
           least 25% in principal amount of the outstanding Junior  Subordinated
           Debentures of such series; or



       (d) certain events in  bankruptcy,  insolvency or  reorganization  of the
           Company.


     In each and  every  such  case,  unless  the  principal  of all the  Junior
Subordinated  Debentures  of that  series  shall  have  already  become  due and
payable,  either the  Indenture  Trustee or the  holders of not less than 25% in
aggregate principal amount of the Junior Subordinated  Debentures of that series
then  outstanding,  by notice in writing to the  Company  (and to the  Indenture
Trustee if given by such  holders),  may declare the principal of all the Junior
Subordinated  Debentures of that series to be due and payable  immediately,  and
upon any such declaration the same shall become and shall be immediately due and
payable. (Section 6.01) 


                                       56
<PAGE>


     The holders of a majority in aggregate  outstanding principal amount of the
Junior Subordinated Debentures of that series have the right to direct the time,
method and place of conducting any  proceeding  for any remedy  available to the
Indenture  Trustee.  (Section 6.06) The Indenture  Trustee or the holders of not
less  than  25%  in  aggregate   outstanding  principal  amount  of  the  Junior
Subordinated Debentures of that series may declare the principal due and payable
immediately upon an Indenture Event of Default with respect to such series,  but
the holders of a majority in aggregate  outstanding  principal  amount of Junior
Subordinated  Debentures of such series may annul such declaration and waive the
default if the  default has been cured and a sum  sufficient  to pay all matured
installments of interest and principal  otherwise than by  acceleration  and any
premium has been deposited with the Indenture Trustee. (Sections 6.01 and 6.06)

     The holders of a majority in aggregate  outstanding principal amount of the
Junior  Subordinated  Debentures of that series may, on behalf of the holders of
all the Junior Subordinated  Debentures of that series,  waive any past default,
except a default in the  payment of  principal,  premium,  if any,  or  interest
(unless  such  default  has been cured and a sum  sufficient  to pay all matured
installments of interest and principal  otherwise than by  acceleration  and any
premium has been deposited with the Indenture  Trustee) or a call for redemption
of Junior  Subordinated  Debentures.  (Section  6.06) The Company is required to
file annually with the Indenture  Trustee a certificate as to whether or not the
Company  is in  compliance  with all the  conditions  and  covenants  under  the
Indenture. (Section 5.03)

     If Junior  Subordinated  Debentures  are issued to AES Trust in  connection
with the issuance of Trust Securities,  then under the applicable Declaration an
Indenture  Event of Default with  respect to such series of Junior  Subordinated
Debentures will constitute a Declaration Event of Default.


MODIFICATION OF THE INDENTURE

     The Indenture contains provisions  permitting the Company and the Indenture
Trustee,  with the  consent  of the  holders  of not  less  than a  majority  in
principal  amount of the  outstanding  Junior  Subordinated  Debentures  of each
series affected, to modify the Indenture or any supplemental indenture affecting
the rights of the holders of such Junior Subordinated Debentures;  provided that
no such  modification may, without the consent of the holder of each outstanding
Junior Subordinated Debenture affected thereby, (i) extend the fixed maturity of
any Junior  Subordinated  Debentures of any series,  reduce the principal amount
thereof,  reduce the rate or extent the time of  payment  of  interest  thereon,
reduce any premium payable upon the redemption  thereof,  without the consent of
the holder of each Junior Subordinated  Debenture so affected or (ii) reduce the
percentage of Junior Subordinated Debentures,  the holders of which are required
to consent to any such modification,  without the consent of the holders of each
Junior  Subordinated  Debenture then outstanding and affected thereby.  (Section
9.02)


CONSOLIDATION, MERGER AND SALE

     The  Indenture  will provide that the Company may not  consolidate  with or
merge  into any other  person or  transfer  or lease its  properties  and assets
substantially  as an  entirety  to any  person  and may not permit any person to
merge into or consolidate with the Company unless (i) either the Company will be
the resulting or surviving entity or any successor or purchaser is a corporation
organized  under  the laws of the  United  States of  America,  any State or the
District of Columbia,  and any such successor or purchaser expressly assumes the
Company's  obligations  under the  Indenture and (ii)  immediately  after giving
effect  to the  transaction  no Event of  Default  shall  have  occurred  and be
continuing. (Section 10.01)


DEFEASANCE AND DISCHARGE

     Under the terms of the Indenture,  the Company will be discharged  from any
and all obligations in respect of the Junior Subordinated Debentures of a series
(except  in each case for  certain  obligations  to  register  the  transfer  or
exchange  of  such  Junior  Subordinated  Debentures,  replace  stolen,  lost or
mutilated  Junior  Subordinated  Debentures  of  that  series,  maintain  paying
agencies  and hold moneys for  payment in trust) if (i) the Company  irrevocably
deposits with the Indenture Trustee cash or U.S. 


                                       57

Government  Obligations,  as trust funds in an amount certified to be sufficient
to pay at maturity (or upon  redemption) the principal of, premium,  if any, and
interest on all outstanding Junior Subordinated  Debentures of such series; (ii)
such  deposit  will not  result in a breach or  violation  of, or  constitute  a
default under, any agreement or instrument to which the Company is a party or by
which it is bound;  (iii) the  Company  delivers  to the  Indenture  Trustee  an
opinion of counsel to the  effect  that the  holders of the Junior  Subordinated
Debentures  of such series will not  recognize  income,  gain or loss for United
States  federal  income tax  purposes  as a result of such  defeasance  and that
defeasance  will not otherwise  alter holders'  United States federal income tax
treatment  of   principal,   premium  and  interest   payments  on  such  Junior
Subordinated  Debentures  of such series (such opinion must be based on a ruling
of the Internal  Revenue Service or a change in United States federal income tax
law  occurring  after the date of the  Indenture,  since such a result would not
occur under  current tax law);  (iv) the Company has  delivered to the Indenture
Trustee an Officer's  Certificate  and an opinion of counsel,  each stating that
all conditions precedent provided for relating to the defeasance contemplated by
such  provision  have been complied  with;  and (v) no event or condition  shall
exist that, pursuant to the subordination  provisions applicable to such series,
would prevent the Company from making payments of principal of, premium, if any,
and interest on the Junior Subordinated Debentures of such series at the date of
the irrevocable deposit referred to above. (Section 11.01)



GOVERNING LAW

     The  Indenture  and  the Junior Subordinated Debentures are governed by the
laws of the State of New York. (Section 13.05)


INFORMATION CONCERNING THE INDENTURE TRUSTEE

     The Indenture  Trustee,  prior to default,  undertakes to perform only such
duties as are specifically set forth in the Indenture and, after default,  shall
exercise the same degree of care as a prudent  individual  would exercise in the
conduct of his or her own affairs. (Section 7.01) Subject to such provision, the
Indenture Trustee is under no obligation to exercise any of the powers vested in
it by the  Indenture  at  the  request  of any  holder  of  Junior  Subordinated
Debentures,  unless  offered  reasonable  indemnity  by such holder  against the
costs,  expenses and liabilities that might be incurred thereby.  (Section 7.02)
The  Indenture  Trustee  is not  required  to  expend  or risk its own  funds or
otherwise incur personal financial liability in the performance of its duties if
the Trustee  reasonably  believes  that  repayment or adequate  indemnity is not
reasonably assured to it. (Section 7.01)

     The  Company  and its  subsidiaries  maintain  ordinary  banking  and trust
relationships with The First National Bank of Chicago and its affiliates.


MISCELLANEOUS

     The Company will have the right at all times to assign any of its rights or
obligations under the Indenture to a direct or indirect wholly-owned  subsidiary
of the Company; provided that, in the event of any such assignment,  the Company
will remain jointly and severally  liable for all such  obligations.  Subject to
the  foregoing,  the Indenture  will be binding upon and inure to the benefit of
the parties thereto and their respective  successors and assigns.  The Indenture
provides that it may not otherwise be assigned by the parties thereto other than
by the Company to a successor or purchaser  pursuant to a consolidation,  merger
or sale permitted by the Indenture. (Section 13.11)


BOOK-ENTRY AND SETTLEMENT

     If distributed to holders of TECONS in connection  with the  involuntary or
voluntary dissolution, winding-up or liquidation of the Trust as a result of the
occurrence of a Special Event, the Junior Subordinated Debentures will be issued
(i) if to owners of beneficial  interests in the Global  TECONS,  in the form of
one or more global  certificates  (each, a "Global Security")  registered in the
name of the  Depositary  or its  nominee or (ii) if to  holders of  certificated
TECONS, in registered form (each, a "Certificated  Security").  Except under the
limited circumstances described below, Junior Subordinated 


                                       58
<PAGE>

Debentures  represented by the Global Security will not be exchangeable for, and
will not otherwise be issuable as, Junior Subordinated  Debentures in definitive
form. The Global Securities described above may not be transferred except by the
Depositary to a nominee of the  Depositary or by a nominee of the  Depositary to
the Depositary or another nominee of the Depositary or to a successor Depositary
or its nominee.

     The  laws  of  some  jurisdictions   require  that  certain  purchasers  or
securities take physical  delivery of such  securities in definitive  form. Such
laws may impair the ability to transfer  beneficial  interests  in such a Global
Security.

     Except as provided herein,  owners of beneficial interests in such a Global
Security  will  not  be  entitled  to  receive   physical   delivery  of  Junior
Subordinated  Debentures  in  definitive  form and will  not be  considered  the
holders  (as  defined  in the  Indenture)  thereof  for any  purpose  under  the
Indenture and no Global Security  representing  Junior  Subordinated  Debentures
shall be exchangeable,  except for another Global Security of like  denomination
and  tenor  to be  registered  in the  name of the  Depositary  or its  nominee.
Accordingly, each beneficial owner of an interest in a Global Security must rely
on the procedures of the Depositary, or, if such person is not a Participant, on
the procedures of the  Participant  through which such person owns its interest,
to exercise any rights of a holder under the Indenture.

THE DEPOSITARY

     If Junior  Subordinated  Debentures are distributed to holders of TECONS in
liquidation of such holders'  interests in the Trust, DTC will act as Depositary
for  the  Junior  Subordinated  Debentures.  For a  description  of DTC  and the
specific terms of the Depositary arrangements, see "Description of the TECONS --
The Global TECONS." As of the date of this Prospectus,  the description  therein
of DTC's  book-entry  system and DTC's and Euroclear's and Cedel's  practices as
they relate to  purchases,  transfers,  notices and payments with respect to the
TECONS apply in all material respects to any debt obligations represented by one
or more  Global  Securities  held by the  Company.  The  Company  may  appoint a
successor to DTC or any successor  Depositary in the event DTC or such successor
Depositary  is unable or unwilling  to continue as a  Depositary  for the Global
Securities.

     None of the Company,  the Trust, the Property Trustee, any paying agent and
any  other  agent  of the  Company  or  the  Indenture  Trustee  will  have  any
responsibility  or  liability  for any  aspect  of the  records  relating  to or
payments made on account of beneficial  ownership interests in a Global Security
for such Junior  Subordinated  Debentures  or for  maintaining,  supervising  or
reviewing any records relating to such beneficial ownership interests.

DISCONTINUANCE OF THE DEPOSITARY'S SERVICES

     A Global Security shall be exchangeable for Junior Subordinated  Debentures
registered in the names of persons other than the Depositary or its nominee only
if (i) the  Depositary  notifies  the Company  that it is unwilling or unable to
continue as a depositary  for such Global  Security and no successor  depositary
shall have been  appointed,  (ii) the  Depositary,  at any time,  ceases to be a
clearing agency  registered under the Exchange Act, at which time the Depositary
is required  to be so  registered  to act as such  depositary  and no  successor
depositary shall have been appointed, (iii) the Company, in its sole discretion,
determines  that such Global  Security  shall be so  exchangeable  or (iv) there
shall have occurred an Event of Default with respect to such Junior Subordinated
Debentures.  Any Global Security that is exchangeable  pursuant to the preceding
sentence shall be exchangeable for Junior Subordinated  Debentures registered in
such names as the Depositary shall direct. It is expected that such instructions
will be based upon directions  received by the Depositary from its  Participants
with respect to ownership of beneficial interests in such Global Security.


                  RELATIONSHIP BETWEEN THE TECONS, THE JUNIOR
                   SUBORDINATED DEBENTURES AND THE GUARANTEE

     As set forth in the  Declaration,  the Trust exists for the sole purpose of
(a) issuing the Trust Securities  evidencing  undivided  beneficial interests in
the assets of the Trust,  and investing the proceeds from such issuance and sale
in the Junior Subordinated  Debentures and (b) engaging in such other activities
as are necessary and incidental thereto. 


                                       59
<PAGE>


     As long as payments of interest and other payments are made when due on the
Junior  Subordinated  Debentures,  such  payments  will be  sufficient  to cover
distributions  and other  payments due on the TECONS  primarily  because (i) the
aggregate  principal  amount of  Junior  Subordinated  Debentures  held as trust
assets will be equal to the sum of the aggregate  stated  liquidation  amount of
the TECONS and the  proceeds  received by the Trust upon  issuance of the Common
Securities to the Company; (ii) the interest rate and interest and other payment
dates on the Junior Subordinated Debentures will match the distribution rate and
distribution  and other  payment  dates for the  TECONS;  (iii) the  Declaration
provides  that the Company shall pay for all debts and  obligations  (other than
with respect to the Trust  Securities)  and all costs and expenses of the Trust,
including  any taxes and all costs and expenses with respect  thereto,  to which
the Trust may become subject,  except for United States  withholding  taxes; and
(iv) the  Declaration  further  provides  that the  Trustees  shall not cause or
permit the Trust,  among other  things,  to engage in any  activity  that is not
consistent with the limited purposes of the Trust.  With respect to clause (iii)
above,  however, no assurance can be given that the Company will have sufficient
resources  to enable it to pay such debts,  obligations,  costs and  expenses on
behalf of the Trust.


     Payments  of  distributions  and  other  payments  due  on the  TECONS  are
guaranteed by the Company on a subordinated basis as and to the extent set forth
under  "Description  of the Guarantee." If the Company does not make interest or
other payments on the Junior  Subordinated  Debentures,  the Trust will not make
distributions or other payments on the TECONS. Under the Declaration,  if and to
the  extent the  Company  does make  interest  or other  payments  on the Junior
Subordinated Debentures, the Property Trustee is obligated to make distributions
or other  payments  on the TECONS.  The  Guarantee  is a full and  unconditional
guarantee  from the time of  issuance of the TECONS,  but the  Guarantee  covers
distributions  and other  payments  on the TECONS only if and to the extent that
the Company has made a payment to the Property  Trustee of interest or principal
on the Junior Subordinated Debentures deposited in the Trust as trust assets.


     The Property Trustee will have the Power to exercise all rights, powers and
privileges  under  the  Indenture  with  respect  to  the  Junior   Subordinated
Debentures,  including  its  rights  as the  holder of the  Junior  Subordinated
Debentures to enforce the Company's  obligations  under the Junior  Subordinated
Debentures upon the occurrence of an Indenture  Event of Default,  and will also
have the right to enforce the  Guarantee on behalf of the holders of the TECONS.
In  addition,  the holders of at least a majority in  liquidation  amount of the
TECONS  will have the right to direct  the  Property  Trustee  with  respect  to
certain matters under the Declaration and the Guarantee. If the Property Trustee
fails to enforce its rights under the Trust  Indenture any holder of TECONS may,
after a period of 30 days has elapsed from such holder's  written request to the
Property Trustee to enforce such rights,  institute a legal  proceeding  against
the Company to enforce such rights. If the Property Trustee fails to enforce the
Guarantee,  to the extent  permitted by applicable law, any holder of TECONS may
institute  a legal  proceeding  directly  against  the  Company to  enforce  the
Property Trustee's rights under the Guarantee. Notwithstanding the foregoing, if
the  Company  has  failed to make a  guarantee  payment,  a holder of TECONS may
directly  institute a  proceeding  against the  Company for  enforcement  of the
Guarantee for such payment.  See "Description of the TECONS" and "Description of
the Guarantee."


     The above  mechanisms and obligations,  taken together,  provide a full and
unconditional guarantee by the Company of payments due on the TECONS.



                        CERTAIN FEDERAL TAX CONSEQUENCES


     In the  opinion of Davis Polk &  Wardwell,  counsel to the  Company and the
Trust,  the  following  are  the  material  United  States  federal  income  tax
consequences  of the  ownership  and  disposition  of TECONS.  Unless  otherwise
stated,  this summary  deals only with TECONS held as capital  assets by holders
who acquire  the TECONS upon  original  issuance at the price  indicated  on the
cover of this Prospectus. It does not deal with special classes of holders, such
as dealers in  securities  or  currencies,  life  insurance  companies,  persons
holding  TECONS  as part of a  straddle  or as part of a hedging  or  conversion
transaction,  or persons  whose  functional  currency  is not the United  States
dollar. This summary is 


                                       60
<PAGE>

based on the Internal  Revenue Code of 1986, as amended (the  "Code"),  Treasury
Regulations thereunder and administrative and judicial  interpretations  thereof
as of the date  hereof,  all of which  are  subject  to  change  (possibly  on a
retroactive basis).

     INVESTORS ARE ADVISED TO CONSULT THEIR TAX ADVISORS AS TO THE UNITED STATES
FEDERAL INCOME TAX  CONSEQUENCES  OF THE OWNERSHIP AND  DISPOSITION OF TECONS IN
LIGHT OF THEIR  PARTICULAR  CIRCUMSTANCES,  AS WELL AS THE  EFFECT OF ANY STATE,
LOCAL OR OTHER TAX LAWS.


CLASSIFICATION OF THE JUNIOR SUBORDINATED DEBENTURES

     The  Company  intends to take the  position  that the  Junior  Subordinated
Debentures  will be classified  for United States federal income tax purposes as
indebtedness.  However,  no assurance can be given,  that this  characterization
will not be  challenged  by the  Internal  Revenue  Service or the  courts.  The
remainder of this  discussion  assumes that the  characterization  of the Junior
Subordinated Debentures as indebtedness of the Company will be respected.


CLASSIFICATION OF THE TRUST

     Davis Polk & Wardwell,  counsel to the  Company and the Trust,  will render
its opinion  generally to the effect that,  assuming  full  compliance  with the
terms of the Declaration, the Trust will be classified for United States federal
income tax purposes as a grantor  trust and not as an  association  taxable as a
corporation.  Accordingly, each holder of TECONS will be considered the owner of
a pro rata portion of the Junior  Subordinated  Debentures held by the Trust and
will be required to include in gross income its pro rata share of income accrued
on the Junior Subordinated Debentures.


ACCRUAL OF ORIGINAL ISSUE DISCOUNT

     The Junior  Subordinated  Debentures will be considered to have been issued
with "original  issue  discount"  ("OID").  Accordingly,  each holder of TECONS,
including a taxpayer who otherwise uses the cash method of  accounting,  will be
required to include its pro rata share of original  issue discount on the Junior
Subordinated  Debentures in income as it accrues,  in accordance with a constant
yield method  based on a  compounding  of  interest,  before the receipt of cash
distributions  on the  TECONS.  Generally,  all of a holder's  taxable  interest
income with respect to the Junior Subordinated  Debentures will be accounted for
as "original  issue discount" and actual  distributions  of stated interest will
not be separately  reported as taxable income.  So long as the interest  payment
period  is not  extended,  cash  distributions  received  by a  holder  for  any
quarterly  interest period (assuming no disposition prior to the record date for
such  distribution) will generally equal the sum of the daily accruals of income
for such quarterly interest period.

     The total amount of "original  issue  discount" on the Junior  Subordinated
Debentures  will equal the  difference  between the "issue  price" of the Junior
Subordinated Debentures and their "stated redemption price at maturity." Because
the Company has the right to extend the  interest  payment  period of the Junior
Subordinated  Debentures,  all of the  stated  interest  payments  on the Junior
Subordinated   Debentures  will  be  includable  in  determining  their  "stated
redemption price at maturity." The "issue price" of each $50 principal amount of
Junior Subordinated Debentures will be equal to the first price to the public at
which a substantial  amount of the TECONS is sold for cash, which is expected to
be $50.

     A  holder's  initial  tax  basis  for  its pro  rata  share  of the  Junior
Subordinated  Debentures  will be equal to its pro  rata  share of their  "issue
price," as defined  above,  and will be  increased  by original  issue  discount
accrued  with  respect  to  its  pro  rata  share  of  the  Junior  Subordinated
Debentures,  and  reduced  by the  amount  of cash  distributions  with  respect
thereto.  No portion of the amounts  received on the TECONS will be eligible for
the dividends received deduction.


POTENTIAL EXTENSION OF PAYMENT PERIOD ON THE JUNIOR SUBORDINATED DEBENTURES

     Holders of TECONS will  continue to accrue  original  issue  discount  with
respect to their pro rata share of the Junior Subordinated  Debentures during an
extended  interest  payment period ever though cash  distributions on TECONS are
deferred. A holder who disposes of the TECONS during an ex- 


                                       61
<PAGE>


tended  interest period may suffer a loss because the market will likely fall if
AES  exercises  its  option  to  defer   payments  of  interest  on  the  Junior
Subordinated Debentures. See "Disposition of the TECONS" below. Furthermore, the
market value of the TECONS may not reflect the  accumulated  distributions  that
will be paid at the end of the extended interest period,  and a holder who sells
the TECONS  during the  extended  interest  period will not receive from AES any
cash related to the interest  income the holder already  accrued and included in
its taxable  income  under the OID rule  (because  that cash will be paid to the
holder of record at the end of the extended interest period).


DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES TO HOLDERS OF TECONS

     A  distribution  by the  Trust of the  Junior  Subordinated  Debentures  as
described  under  the  caption  "Description  of the  TECONS  --  Special  Event
Redemption or  Distribution"  will be non-taxable  and will result in the holder
receiving  directly  its pro rata  share of the Junior  Subordinated  Debentures
previously  held  indirectly  through the Trust,  with a holding  period and tax
basis  equal to the  holding  period  and  adjusted  tax basis  such  holder was
considered  to  have  had  in its  pro  rata  share  of  the  underlying  Junior
Subordinated Debentures prior to such distribution.


DISPOSITION OF THE TECONS

     Upon a sale,  exchange  or other  disposition  of the TECONS  (including  a
distribution  of cash in  redemption  of a holder's  TECONS upon  redemption  or
repayment of the underlying Junior  Subordinated  Debentures,  but excluding the
distribution of Junior Subordinated Debentures),  a holder will be considered to
have  disposed  of all or part of its pro rata share of the Junior  Subordinated
Debentures,  and will  recognize  capital  gain or loss equal to the  difference
between the amount realized and the holder's  adjusted tax basis in its pro rata
share of the  underlying  Junior  Subordinated  Debentures  deemed  disposed of.
Holders are advised to consult  their tax  advisers  regarding  the  taxation of
capital gains and losses.

     The TECONS may trade at a price  that does not fully  reflect  the value of
accrued but unpaid interest with respect to the underlying  Junior  Subordinated
Debentures.  A holder  who  disposes  of its  TECONS  between  record  dates for
payments of distributions  thereon will nevertheless be required to include,  as
OID  income,  the  amount of any  accrued  but  unpaid  interest  on the  Junior
Subordinated  Debentures  through the date of disposition in income,  and to add
such amount to its  adjusted  tax basis in its pro rata share of the  underlying
Junior Subordinated  Debentures deemed disposed of.  Accordingly,  such a holder
will  recognize a capital  loss to the extent the selling  price  (which may not
fully  reflect the value of such  accrued but unpaid  interest) is less than the
holder's  adjusted tax basis (which will include  accrued but unpaid  interest).
Subject to  certain  limited  exceptions,  capital  losses  cannot be applied to
offset ordinary income (including any previously included OID income) for United
States federal income tax purposes.


CONVERSION OF TECONS TO AES COMMON STOCK

     A  holder  of  TECONS  will not  recognize  income,  gain or loss  upon the
conversion through the Conversion Agent, of Junior Subordinated  Debentures into
AES Common  Stock.  A holder of TECONS will  recognize  gain upon the receipt of
cash in lieu of a  fractional  share of AES Common  Stock equal to the amount of
cash  received  less such  holder's  tax basis in such  fractional  share.  Such
holder's  tax  basis in the AES  Common  Stock  received  upon  conversion  will
generally  be equal to such  holder's  tax basis in the TECONS  delivered to the
Conversion Agent for exchange,  less the basis allocated to any fractional share
for which cash is received. Such holder's holding period in the AES Common Stock
received upon conversion will generally  include the holder's  holding period of
the TECONS delivered to the Conversion Agent for exchange,  except possibly with
respect to AES Common Stock received in respect of any accrued but unpaid OID.


ADJUSTMENT OF CONVERSION PRICE

     Treasury Regulations  promulgated under section 305 of the Code would treat
holders of TECONS as having  received a  constructive  distribution  from AES in
certain events pursuant to which the conversion rate of the Junior  Subordinated
Debentures were adjusted. Therefore, under certain circumstances, 


                                       62
<PAGE>

a reduction in the conversion price for the Junior  Subordinated  Debentures may
result  in deemed  dividend  income to  holders  of TECONS to the  extent of the
current  or  accumulated  earnings  and  profits  of AES.  Holders of TECONS are
advised to consult  their tax  advisors  as to the  income tax  consequences  of
adjustments in the conversion rate of TECONS.



INFORMATION REPORTING TO HOLDERS

     The Trust will report the original  issue  discount that accrued during the
year with respect to the Junior Subordinated Debentures,  and any gross proceeds
received  by  the  Trust  from  the  retirement  or  redemption  of  the  Junior
Subordinated Debentures, annually to the holders of record of the TECONS and the
Internal Revenue Service. The Trust currently intends to deliver such reports to
holders of record  prior to January  31  following  each  calendar  year.  It is
anticipated that persons who hold TECONS as nominees for beneficial holders will
report the required tax information to beneficial holders on Form 1099.


BACKUP WITHHOLDING

     Payments  made on, and proceeds from the sale of TECONS may be subject to a
"backup"  withholding  tax at a rate of 31%  unless  the  holder  complies  with
certain identification requirements. Backup withholding is not an additional tax
and may be refunded or allowed as a credit  against the holder's  federal income
tax, provided the required information is timely filed with the Internal Revenue
Service.


UNITED STATES ALIEN HOLDERS

     For purposes of this  discussion,  a "United  States  Alien  Holder" is any
corporation,  individual, partnership, estate or trust that is, for U.S. federal
income tax purposes,  a foreign corporation,  a nonresident alien individual,  a
foreign partnership, or a non-resident fiduciary of a foreign estate or trust.

     Payments on TECONS.  As discussed  above,  the Company  intends to take the
position that the Junior  Subordinated  Debentures  will be classified  for U.S.
federal  income tax  purposes  as  indebtedness  of AES under  current  law;  no
assurance can be given,  however,  that such position of the Company will not be
challenged by the Internal Revenue Service.

     Assuming that the Junior  Subordinated  Debentures  are classified for U.S.
federal income tax purposes as indebtedness  of AES, under present U.S.  federal
income tax law,  payments by the Trust or any of its paying agents to any holder
of a TECONS who or which is a United States Alien Holder would not be subject to
U.S. federal  withholding tax;  provided,  that, (a) the beneficial owner of the
TECONS does not actually or constructively own 10% or more of the total combined
voting power of all classes of stock of AES entitled to vote, (b) the beneficial
owner of the TECONS is not a controlled  foreign  corporation that is related to
AES through  stock  ownership,  and (c) either (A) the  beneficial  owner of the
TECONS certifies to the Trust or its agent, under penalties of perjury,  that it
is not a U.S.  person and  provides  its name and  address  or (B) a  securities
clearing organization, bank or other financial institution that holds customers'
securities  in the  ordinary  course  of its  trade or  business  (a  "Financial
Institution"),  and holds the TECONS in such capacity, certifies to the Trust or
its agent,  under  penalties of perjury,  that such  statement has been received
from the beneficial owner by it or by a Financial Institution between it and the
beneficial owner and furnishes the Trust or its agent with a copy thereof.

     If the Junior Subordinated  Debentures were not classified for U.S. federal
income tax purposes as indebtedness of AES,  payments by the Trust or any of its
paying  agents to any holder of a TECONS who or which is a United  States  Alien
Holder would be subject to U.S.  withholding  tax at a 30% rate (or a lower rate
prescribed by an applicable  tax treaty).  Prospective  investors  that would be
United States Alien Holders  should  consult their tax advisors  concerning  the
possible application of these rules.

     Dividends on AES Common Stock.  Subject to the discussion below,  dividends
paid to a United  States  Alien  Holder of AES Common  Stock  generally  will be
subject to withholding  tax at a 30% rate or such lower rate as may be specified
by an applicable income tax treaty.  For purposes of determining  whether tax is
to be withheld at a 30% rate or at a reduced  rate as specified by an income tax
treaty, the 


                                       63
<PAGE>


Company  ordinarily will presume that dividends paid before December 31, 1998 to
an address in a foreign  country are paid to a resident of such country,  unless
the Company has knowledge that such a presumption is not warranted.

     Under the recently finalized Treasury  Regulations  applicable to dividends
paid after December 31, 1998 (the "Final Regulations"), to obtain a reduced rate
of  withholding  under a treaty,  a United States Alien Holder will generally be
required  to  provide  an  Internal  Revenue  Service  form W-8  certifying  its
entitlement to benefits under a treaty.  The  Regulations  also provide  special
rules to determine  whether,  for purposes of determining the applicability of a
tax treaty,  dividends  paid to a United  States  Alien Holder that is an entity
will be  treated  as having  been  paid to the  entity  or to those  holding  an
interest in that entity.

     Generally, the Company must report to the U.S. Internal Revenue Service the
amount of dividends paid, the name and address of the recipient, and the amount,
if any, of tax withheld. A similar report is sent to the holder. Pursuant to tax
treaties or certain other agreements, the U.S. Internal Revenue Service may make
its  reports  available  to  tax  authorities  in  the  recipient's  country  of
residence.

     Sale or  Exchange  of TECONS or AES Common  Stock.  A United  States  Alien
Holder (other than certain U.S. expatriates) will not be subject to U.S. federal
income tax on gain  realized  on a sale,  exchange or other  disposition  of the
TECONS or AES  Common  Stock  unless (i) the United  States  Alien  Holder is an
individual  who is present in the U.S.  for 183 days or more in the taxable year
of disposition,  and certain other  conditions are satisfied;  or (ii) AES is or
has been a "United States real property holding  corporation" within the meaning
of section  897(c)(2) of the Code during the shorter of the United  States Alien
Holder's  holding period or the five year period ending on the date of the sale,
exchange or other disposition and certain other conditions are satisfied.

     The Company believes that it is unlikely that it is or will be treated as a
"United States real property holding  corporation" within the meaning of Section
897(c)(2) of the Code.  Even if AES is treated as a United  States real property
holding  corporation,  gain  realized  by a  United  States  Alien  Holder  on a
disposition  of TECONS or AES Common  Stock will not be subject to U.S.  federal
income  tax so long as (i) the  United  States  Alien  Holder  is deemed to have
beneficially  owned, in the case of a disposition of AES Common Stock, less than
or equal to 5% of the AES  Common  Stock  or,  in the case of a  disposition  of
TECONS,  less than or equal to 5% of the TECONS,  and (ii) the AES Common  Stock
and the TECONS are currently and will be, at the time of disposition, "regularly
traded" on an  established  securities  market  (within  the  meaning of Section
897(c)(3) of the Code and the temporary  Treasury  Regulations  (the  "Temporary
Regulations")).  There can be no  assurance  that AES Common Stock or the TECONS
qualify or will  continue  to qualify as  "regularly  traded" on an  established
securities market.

     Effectively  Connected Income. If a United States Alien Holder of TECONS or
AES Common Stock is engaged in a trade or business in the United States,  and if
original issue discount  accrued on the TECONS or dividends on such Common Stock
is effectively connected with the conduct of such trade or business,  the United
States Alien Holder,  although exempt from the withholding tax on  distributions
on TECONS  and  dividends  on AES Common  Stock,  will  generally  be subject to
regular  United States income tax on the original  issue  discount and dividends
and on any gain realized on the sale, exchange or other disposition of TECONS or
AES Common Stock in the same manner as if it were a United States person. Such a
holder  will be  required  to provide to the  Company  with a properly  executed
Internal  Revenue  Service Form 4224 (or a successor  form) in order to claim an
exemption  from  withholding  tax. On or after December 31, 1998, to comply with
this  requirement,  the United States Alien Holder needs to also provide a valid
United States taxpayer identification number. In addition, if such United States
Alien Holder is a foreign corporation, it may be subject to a branch profits tax
equal  to 30%  (or a lower  rate  prescribed  by an  applicable  treaty)  of its
effectively connected earnings and profits for the taxable year.

                             ERISA CONSIDERATIONS


GENERAL

     A fiduciary of an employee  benefit plan subject of Title I of ERISA should
consider  fiduciary  standards  under  ERISA in the  context  of the  particular
circumstances of such plan before authorizing an investment in the TECONS.  Such
fiduciary   should   consider   whether   the   investment   satisfies   ERISA's
diversification and prudence  requirements,  whether the investment  constitutes
unauthorized  delegation of fiduciary authority and whether the investment is in
accordance with the documents and  instruments  governing the plan. In addition,
ERISA  and  the  Code  prohibit  a  wide  range  of  transactions   ("Prohibited
Transactions")  involving the assets of a plan subject to ERISA or the assets of
an  individual  retirement  account or plan  subject to Section 4975 of the Code
(hereinafter   an  "ERISA   Plan")  and  persons  who  have  certain   specified
relationships  to the ERISA Plan  ("parties in interest,"  within the meaning of
ERISA,  and  "disqualified  persons,"  within the  meaning  of the  Code).  Such
transactions may require  "correction" and may cause the ERISA Plan fiduciary to
incur certain liabilities and the parties in interest or disqualified persons to
be subject to excise taxes.

     The  acquisition of TECONS by any person who is using for such  acquisition
the assets of an ERISA Plan shall constitute a representation  by such person to
AES that (i) if AES is a "party in  interest"  or a  "disqualified  person" with
respect to such ERISA Plan, then such security is being acquired  pursuant to an
exemption  from the Prohibited  Transaction  rules under ERISA and the Code, and
(ii) AES is not a "fiduciary,"  within the meaning of Section 3(21) of ERISA and
the regulations thereunder, with respect to such person's interest in the TECONS
or the Junior Subordinated Debentures.

     Governmental  plans and certain  church plans (each as defined under ERISA)
are not subject to the Prohibited Transaction rules. Such plans may, however, be
subject to federal,  state or local laws or  regulations  which may affect their
investment in the TECONS.  Any fiduciary of such a  governmental  or church plan
considering  an investment in the TECONS should  determine the need for, and the
availability,  if  necessary,  of  any  exemptive  relief  under  such  laws  or
regulations.

     THE DISCUSSION  HEREIN OF ERISA IS GENERAL IN NATURE AND IS NOT INTENDED TO
BE ALL INCLUSIVE.  ANY FIDUCIARY OF AN ERISA PLAN,  GOVERNMENTAL  PLAN OR CHURCH
PLAN  CONSIDERING  AN  INVESTMENT  IN THE TECONS  SHOULD  CONSULT WITH ITS LEGAL
ADVISORS REGARDING THE CONSEQUENCES OF SUCH INVESTMENT.


PROHIBITED TRANSACTIONS

     AES may be a party in interest or a disqualified  person with respect to an
ERISA Plan investing in the TECONS, and, therefore, such investments by an ERISA
Plan may give rise to a Prohibited Transaction.  Consequently,  before investing
in the TECONS,  any person who is, or who in acquiring such  securities is using
the assets of, an ERISA Plan should  determine  that  either a  statutory  or an
administrative  exemption from the Prohibited  Transaction rules discussed below
or otherwise  available is applicable to such person's investment in the TECONS,
or that its  investment  in such  securities  will not  result  in a  Prohibited
Transaction.

     Certain  statutory  or   administrative   exemptions  from  the  Prohibited
Transaction  rules  under ERISA and the Code may be  available  to an ERISA Plan
which  is  investing  in  the  TECONS.  Included  among  these  exemptions  are:
Prohibited  Transaction Class Exemption ("PTCE") 90-1, regarding  investments by
insurance company pooled separate accounts; PTCE 91-38, regarding investments by
bank collective investment funds; PTCE 84-14, regarding transactions effected by
qualified  professional  asset  managers;  PTCE  96-23,  regarding  transactions
effected by in-house asset  managers;  or PTCE 95-60,  regarding  investments by
insurance company general accounts.


TRUST ASSETS AS "PLAN ASSETS"

     The  Department  of  Labor  has  issued  final   regulations   (the  "Labor
Regulations") as to what  constitutes  assets of an employee benefit plan ("plan
asset") under ERISA. The Labor Regulations provide that, as a general rule, when
an ERISA Plan acquires an equity interest in an entity and such interest 


                                       65
<PAGE>

does not represent a "publicly  offered  security"  nor a security  issued by an
investment  company  registered  under the  Investment  Company Act of 1940, the
ERISA Plan's assets include both the equity  interest and an undivided  interest
in each of the underlying assets of the entity,  unless it is established either
that the entity in an  operating  company or that  equity  participation  in the
entity by "benefit  plan  investors" is not  "significant."  For purposes of the
Labor Regulations,  the Trust will not be an investment company nor an operating
company and the TECONS will not  constitute a "publicly  offered  security."  As
discussed below, after resales pursuant to the shelf registration statement, the
TECONS may qualify as "publicly  offered  securities"  for purposes of the Labor
Regulations, but such result cannot be assured.

     Under the Labor Regulations, equity participation by benefit plan investors
will not be considered  "significant" on any date only if, immediately after the
most recent  acquisition of TECONS, the aggregate interest in the TECONS held by
benefit  plan  investors  will be less  than  25% of the  value  of the  TECONS.
Although it is possible that the equity  participation by benefit plan investors
on any date will not be  "significant"  for  purposes of the Labor  Regulations,
such result cannot be assured.  Consequently,  if ERISA Plans or investors using
plan assets of ERISA plans  purchase  the TECONS,  the Trust's  assets  could be
deemed to be "plan  assets"  of such ERISA Plan for  purposes  of the  fiduciary
responsibility  provisions  of ERISA and the Code.  Under ERISA,  any person who
exercises any authority or control  respecting  the management or disposition of
the assets of an ERISA Plan is  considered to be a fiduciary of such ERISA Plan.
For example,  the Property  Trustee  could  therefore  become a fiduciary of the
ERISA Plans that  invest in the TECONS and be subject to the  general  fiduciary
requirements of ERISA in exercising its authority with respect to the management
of the assets of the Trust. However, the Property Trustee will have only limited
discretionary  authority  with respect to the Trust's  assets and the  remaining
functions and the responsibilities performed by the Property Trustee will be for
the most part  custodial  and  ministerial  in nature.  Inasmuch as the Property
Trustee or another person with authority or control respecting the management or
disposition of the Trust assets may become a fiduciary with respect to the ERISA
Plans that will purchase the TECONS, there may be an improper delegation by such
ERISA Plans of the responsibility to manage plan assets.

     It is expected  that TECONS will be  distributed  pursuant to an  effective
registration  statement  under the Securities Act and they may  subsequently  be
registered  under the  Exchange  Act.  TECONS may qualify as  "publicly  offered
securities" under the Labor Regulations if, in addition to such distribution and
registration,  they are also "widely held" and "freely  transferable." Under the
Labor Regulations,  a class of securities is "widely held" only if it is a class
of securities  that is owned by 100 or more investors  independent of the issuer
and of one another.  Although it is possible that after distribution pursuant to
the shelf  registration  statement the TECONS will be "widely held," such result
cannot be assured.  Whether a security is "freely  transferable" for purposes of
the Labor Regulations is a factual question to be determined on the basis of all
relevant  facts and  circumstances.  If after the  distribution  pursuant to the
shelf  registration  statement,  the TECONS do not qualify as "publicly  offered
securities,"  the  "plan  asset"  considerations  discussed  in the  immediately
preceding  paragraph  could  continue to be applicable  in  connection  with the
investment by ERISA Plans or investors' using plan assets of ERISA Plans.

     The holders listed below and the beneficial  owners of the TECONS and their
transferees,  pledgees,  donees or other successors, if not identified hereunder
then so identified in supplements to this  Prospectus,  are the Selling  Holders
under  this  Prospectus.  The  following  table  sets  forth,  as  of  a  recent
practicable date prior to the  effectiveness  of the  Registration  Statement of
which this  Prospectus  forms a part,  certain  information  with respect to the
Selling  Holders named below and the  respective  number of TECONS owned by each
Selling Holder that may be offered pursuant to this Prospectus. Such information
has been obtained from the Selling Holders, DTC and/or the Property Trustee.

</TABLE>



     None of the  Selling  Holders  has, or within the past three years has had,
any  position,  office  or other  material  relationship  with the  Trust or the
Company or any of their predecessors or affiliates other than Roger W. Sant, who
is Chairman of the Board of the  Company.  None of the Selling  Holders owns any
shares of AES Common Stock, other than Roger W. Sant who owns [ ]% of the Common
Stock.  Because the Selling Holders may, pursuant to this Prospectus,  offer all
or some portion of the TECONS,  the Junior  Subordinated  Debentures  or the AES
Common Stock issuable upon conversion of the TECONS, no estimate can be given as
to the amount of the  TECONS,  the  Junior  Subordinated  Debentures  or the AES
Common Stock  issuable  upon  conversion  of the TECONS that will be held by the
Selling  Holders upon  termination of any such sales.  In addition,  the Selling
Holders identified above may have sold, transferred or otherwise disposed of all
or a  portion  of  their  TECONS,  since  the date on which  they  provided  the
information regarding their TECONS, in transactions exempt from the registration
requirements of the Securities Act. See "Plan of Distribution."

     Only Selling  Holders  identified  above who  beneficially  own the Offered
Securities set forth  opposite each such Selling  Holder's name in the foregoing
table  on the  effective  date  of the  Registration  Statement  of  which  this
Prospectus  forms a part  may  sell  such  Offered  Securities  pursuant  to the
Registration  Statement.  The Company may from time to time, in accordance  with
the  Registration  Rights  Agreement,  include  additional  Selling  Holders  in
supplements to this Prospectus. 


                             PLAN OF DISTRIBUTION

     The Offered Securities may be sold from time to time to purchasers directly
by the Selling Holders. Alternatively, the Selling Holders may from time to time
offer the  Offered  Securities  to or through  underwriters,  broker/dealers  or
agents,  who may receive  compensation  in the form of  underwriting  discounts,
concessions  or commissions  from the Selling  Holders or the purchasers of such
securities  for  whom  they  may act as  agents.  The  Selling  Holders  and any
underwriters,  broker/dealers  or agents that participate in the distribution of
Offered Securities may be deemed to be "underwriters"  within the meaning of the
Securities Act, and any profit on the sale of such securities and any discounts,
commissions, concessions or other compensation received by any such underwriter,
broker/dealer  or  agent  may  be  deemed  to  be  underwriting   discounts  and
commissions under the Securities Act.



                                       67
<PAGE>


     The  Offered  Securities  may be  sold  from  time  to  time in one or more
transactions  at fixed prices,  at the  prevailing  market prices at the time of
sale, at varying prices determined at the time of sale or at negotiated  prices.
The sale of  Offered  Securities  may be  effected  in  transactions  (which may
involve crosses or block  transactions) (i) on any national  securities exchange
or quotation service on which the Offered  Securities may be listed or quoted at
the time of sale,  (ii) in the  over-the-counter  market,  (iii) in transactions
otherwise  than on such  exchanges  or in the  over-the-counter  market  or (iv)
through the writing of options. At the time a particular offering of the Offered
Securities is made, a Prospectus  Supplement,  if required,  will be distributed
which will set forth the aggregate  amount and type of Offered  Securities being
offered  and the  terms  of the  offering,  including  the  name or names of any
underwriters,  broker/dealers  or agents,  any discounts,  commissions and other
terms  constituting  compensation  from the Selling  Holders and any  discounts,
commissions or concessions allowed or reallowed or paid to broker/dealers.

     To comply with the securities laws of certain jurisdictions, if applicable,
the  Offered  Securities  will be  offered  or sold in such  jurisdictions  only
through  registered  or licensed  brokers or dealers.  In  addition,  in certain
jurisdictions the Offered Securities may not be offered or sold unless they have
been  registered  or qualified for sale in such  jurisdictions  or any exemption
from registration or qualification is available and is complied with.

     The  Selling  Holders  will be  subject  to  applicable  provisions  of the
Exchange Act and the rules and  regulations  thereunder,  which  provisions  may
limit the timing of purchases and sales of any of the Offered  Securities by the
Selling Holders. The foregoing may affect the marketability of such securities.


     The costs of the registration of the Offered Securities will be paid by the
Company, including,  without limitation,  Commission filing fees and expenses of
compliance with state securities or "blue sky" laws; provided, however, that the
Selling Holders will pay all underwriting discounts and selling commissions,  if
any.  The  Selling  Holders  will be  indemnified  by the Company and the Trust,
jointly and severally  against  certain  civil  liabilities,  including  certain
liabilities  under the Securities  Act, or will be entitled to  contribution  in
connection  therewith.  The  Company  and the Trust will be  indemnified  by the
Selling Holders severally against certain civil  liabilities,  including certain
liabilities  under the Securities  Act, or will be entitled to  contribution  in
connection therewith.

     The Trust does not intend to list the  TECONS on any  securities  exchange.
The Trust has been  advised by the  Initial  Purchasers,  other  than  Unterburg
Harris,  that they intend to make a market in them as  permitted  by  applicable
laws and regulations. The Initial Purchasers are not obligated, however, to make
a market in the TECONS and any such  market-making  may be  discontinued  at any
time at the sole discretion of the Initial Purchasers. Accordingly, no assurance
can be given as to the liquidity of, or trading markets for, the TECONS.


                                 LEGAL MATTERS

     The  validity  of the Junior  Subordinated  Debentures,  the  Common  Stock
issuable  upon  conversion  of the TECONS,  the  Guarantee  and certain  matters
relating thereto and certain U.S. federal income taxation matters will be passed
upon for AES and AES Trust by Davis Polk &  Wardwell,  and the  validity  of the
TECONS will be passed upon for the Company and AES Trust by  Richards,  Layton &
Finger,  Wilmington,  Delaware,  special Delaware counsel to the Company and AES
Trust.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS


INDEMNIFICATION OF DIRECTORS AND OFFICERS OF THE COMPANY


     Under the  Company's  By-Laws,  and in  accordance  with Section 145 of the
Delaware General Corporation Law ("GCL"), the Company shall indemnify any person
who was or is a party or is  threatened  to be made a party  to any  threatened,
pending or  completed  action,  suit or  proceeding,  whether  civil,  criminal,
administrative  or  investigative  (other  than any  action or suit by or in the
right of the  Company to procure a judgment in its favor,  which is  hereinafter
referred to as a "derivative  action") by reason of the fact that such person is
or was a director,  officer or employee of the Company,  or is or was serving in
such  capacity or as an agent at the request of the Company for another  entity,
to the full extent authorized by Delaware law, against expenses (including,  but
not limited to,  attorneys'  fees),  judgments,  fines and amounts  actually and
reasonably incurred in connection with the defense or settlement of such action,
suit or proceeding if such person acted in good faith and in a manner the person
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
Company,  and,  with  respect  to any  criminal  action  or  proceeding,  had no
reasonable cause to believe was unlawful. Agents of the Company may be similarly
indemnified, at the discretion of the Board of Directors.


     Under  Section 145 of the GCL, a similar  standard of care is applicable in
the case of  derivative  actions,  except that  indemnification  only extends to
expenses (including  attorneys' fees) incurred in connection with the defense or
settlement of such an action and then, where the person is adjudged to be liable
to the  Company,  only if and to the extent  that the Court of  Chancery  of the
State of Delaware or the court in which such action was brought  determines that
such person is fairly and  reasonably  entitled to such  indemnity  and only for
such expenses as the court shall deem proper.


     Pursuant to Company's  By-Laws, a person eligible for  indemnification  may
have the expenses incurred in connection with any matter described above paid in
advance of a final disposition by the Company.  However, such advances will only
be made upon the delivery of an undertaking  by or on behalf of the  indemnified
person to repay all amounts so advanced if it is ultimately determined that such
person is not entitled to indemnification.


     In  addition,  under the  Company's  By-Laws,  the Company may purchase and
maintain  insurance  on behalf of any person who is or was a director,  officer,
employee or agent of the Company or of another corporation against any liability

ITEM 17. UNDERTAKINGS.

     The undersigned registrant hereby undertakes:

     (1) To file,  during any period in which  offers or sales are being made of
the  securities   registered   hereby,  a   post-effective   amendment  to  this
registration statement:

       (i) To  include  any  prospectus  required  by  Section  10(a)(3)  of the
 Securities Act;

       (ii) To reflect in the  prospectus  any facts or events arising after the
     effective  date  of  the   registration   statement  (or  the  most  recent
     post-effective amendment thereof) which,  individually or in the aggregate,
     represent  a  fundamental  change  in the  information  set  forth  in this
     registration statement;

       (iii) To include any  material  information  with  respect to the plan of
      distribution not previously disclosed in the registration statement or any
      material  change  to  such  information  in  the  registration  statement;
      provided,  however,  that the undertakings set forth in paragraphs  (1)(i)
      and (1)(ii) above do not apply if the information  required to be included
      in a post-effective amendment by those paragraphs is contained in periodic
      reports  filed  with or  furnished  to the  Commission  by the  registrant
      pursuant to Section 13 or Section 15(d) of the Securities  Exchange Act of
      1934, as amended (the "Exchange  Act") that are  incorporated by reference
      in this registration statement.

     (2) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities  offered therein,  and the offering of such
securities  at that time shall be deemed to be the  initial  bona fide  offering
thereof.


                                      II-3
<PAGE>

     (3) To remove from registration by means of a post-effective  amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     The  undersigned   Registrant  hereby  undertakes  that,  for  purposes  of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Exchange Act (and, where  applicable,  each filing of an employee benefit plan's
annual  report   pursuant  to  Section  15(d)  of  the  Exchange  Act)  that  is
incorporated by reference in the registration  statement shall be deemed to be a
new registration  statement relating to the securities offered therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
registrant pursuant to the foregoing  provisions  described under Item 15 above,
or  otherwise,  the  registrant  has been  advised  that in the  opinion  of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the  Securities  Act and is,  therefore,  unenforceable.  In the
event that a claim for indemnification  against such liabilities (other than the
payment by the registrar of expenses incurred or paid by a director,  officer or
controlling  person of the registrant in the  successful  defense of any action,
suit or proceeding) is asserted by such director,  officer or controlling person
in connection with the securities being registered,  the registrant will, unless
in the  opinion of its  counsel  the matter has been  settled by against  public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

               close of  business  on a special  record  date for the payment of

               manner:  the Company  shall  notify the Trustee in writing of the

               money  equal  to the  aggregate  amount  proposed  to be  paid in
               respect of such  Defaulted  Interest  or shall make  arrangements
               satisfactory to the Trustee for such deposit prior to the date of
               the  proposed  payment,  such money when  deposited to be held in
               trust for the benefit of the persons  entitled to such  Defaulted
               Interest as in this clause provided.  Thereupon the Trustee shall
               fix a  special  record  date for the  payment  of such  Defaulted
               Interest  which  shall  not be more than 15 nor less than 10 days
               prior to the date of the  proposed  payment  and not less than 10
               days  after  the  receipt  by the  Trustee  of the  notice of the
               proposed  payment.  The Trustee shall promptly notify the Company
               of such  special  record date and, in the name and at the expense
               of the Company,  shall cause  notice of the  proposed  payment of
               such  Defaulted  Interest and the special record date therefor to
               be mailed,  first class postage prepaid, to each  Debentureholder
               at his or her address as it appears in the Debenture Register (as
               hereinafter defined), not less than 10 days prior to such special
               record  date.  Notice of the proposed  payment of such  Defaulted
               Interest and the special record date therefor  having been mailed
               as  aforesaid,  such  Defaulted  Interest  shall  be  paid to the

               Debentures)  are registered on such special record date and shall
               be no longer payable pursuant to the following clause (2).

               (2) The Company may make payment of any Defaulted Interest on any
               Debentures in any other lawful manner not  inconsistent  with the
               requirements of any securities  exchange on which such Debentures
               may be listed,  and upon such  notice as may be  required by such
               exchange, if, after notice given by the Company to the Trustee of
               the  proposed  payment  pursuant to this  clause,  such manner of
               payment shall be deemed practicable by the Trustee.

         Unless  otherwise  set  forth  in a  Board  Resolution  or one or  more
indentures   supplemental  hereto  establishing  the  terms  of  any  series  of
Debentures  pursuant to Section 2.01 hereof,  the term "regular  record date" as

the form of a manual or facsimile signature of a present or any future Chairman,
Vice  Chairman,  President  or Vice  President  and of a present  or any  future
Secretary or Assistant Secretary and may be imprinted or otherwise reproduced on
the  Debentures and for that purpose the Company may use the manual or facsimile
signature of any person who shall have been a Chairman, Vice Chairman, President
or Vice President, or of any person who shall have been a Secretary or Assistant
Secretary,  notwithstanding  the fact that at the time the  Debentures  shall be
authenticated  and  delivered or disposed of such person shall have ceased to be
the Chairman, Vice Chairman,  President or a Vice President, or the Secretary or
an  Assistant  Secretary,  of the  Company,  as the case may be. The seal of the
Company may be in the form of a facsimile  of the seal of the Company and may be
impressed, affixed, imprinted or otherwise reproduced on the Debentures.

         Only  such   Debentures  as  shall  bear  thereon  a   Certificate   of
Authentication  substantially  in the  form  established  for  such  Debentures,
executed  manually  by an  authorized  signatory  of  the  Trustee,  or  by  any
Authenticating  Agent with respect to such Debentures,  shall be entitled to the
benefits of this  Indenture  or be valid or  obligatory  for any  purpose.  Such
certificate executed by the Trustee, or by any Authenticating Agent appointed by
the Trustee with respect to such Debentures,  upon any Debenture executed by the
Company shall be conclusive  evidence  that the Debenture so  authenticated  has
been duly  authenticated and made available for delivery  hereunder and that the
holder is entitled to the benefits of this Indenture.

         At any time and from time to time after the  execution  and delivery of
this Indenture, the Company may deliver Debentures of any series executed by the
Company to the Trustee for authentication,  together with a written order of the
Company for the  authentication  and delivery of such Debentures,  signed by its
President or any Vice  President and its  Treasurer or any Assistant  Treasurer,
and the Trustee in  accordance  with such written order shall  authenticate  and
make available for delivery such Debentures.

         In   authenticating   such  Debentures  and  accepting  the  additional
responsibilities  under this  Indenture  in  relation  to such  Debentures,  the
Trustee  shall be entitled to receive,  and  (subject to Section  7.01) shall be
fully protected in relying upon, an Opinion of Counsel stating that the form and
terms thereof have been  established  in conformity  with the provisions of this
Indenture.

         The Trustee shall not be required to  authenticate  such  Debentures if
the  issue  of such  Debentures  pursuant  to this  Indenture  will  affect  the
Trustee's  own  rights,  duties  or  immunities  under the  Debentures  and this
Indenture or otherwise in a manner  which is not  reasonably  acceptable  to the
Trustee.

         SECTION 2.05. Exchange of Debentures.  (a) Debentures of any series may
be exchanged  upon  presentation  thereof at the office or agency of the Company
designated  for such purpose in the Borough of Manhattan,  The City and State of
New York, for other Debentures of such series of authorized  denominations,  and
for a like aggregate principal amount, upon payment of a sum sufficient to cover
any tax or other  governmental  charge in relation  thereto,  all as provided in
this Section.  In respect of any  Debentures so  surrendered  for exchange,  the
Company shall execute,  the Trustee shall authenticate and such office or agency
shall make  available  for  delivery  in  exchange  therefor  the  Debenture  or
Debentures  of the same series  which the  Debentureholder  making the  exchange
shall be entitled to receive, bearing numbers not contemporaneously outstanding.

         (b) The  Company  shall  keep,  or cause to be kept,  at its  office or
agency  designated  for such purpose in the Borough of  Manhattan,  The City and
State of New York, or such other  location  designated by the Company a register
or registers (herein referred to as the "Debenture  Register") in which, subject
to such reasonable  regulations as it may prescribe,  the Company shall register
the Debentures  and the transfers of Debentures as in this Article  provided and
which at all reasonable  times shall be open for inspection by the Trustee.  The
registrar for the purpose of  registering  Debentures and transfer of Debentures
as herein  provided  shall be appointed as authorized by Board  Resolution  (the
"Debenture Registrar").

         Upon surrender for transfer of any Debenture at the office or agency of
the Company  designated  for such purpose in the Borough of Manhattan,  The City
and State of New York, the Company shall execute, the Trustee shall authenticate
and such office or agency shall make  available  for delivery in the name of the
transferee  or  transferees  a new Debenture or Debentures of the same series as
the Debenture presented for a like aggregate principal amount.

         All Debentures presented or surrendered for exchange or registration of
transfer,  as provided in this Section,  shall be accompanied (if so required by
the Company or the Debenture  Registrar) by a written  instrument or instruments
of transfer, in form



                                       14
<PAGE>


satisfactory  to the Company or the  Debenture  Registrar,  duly executed by the
registered holder or by his duly authorized attorney in writing.

         (c) No service charge shall be made for any exchange or registration of
transfer of Debentures, or issue of new Debentures in case of partial redemption
of any series,  but the Company may require payment of a sum sufficient to cover
any tax or other governmental  charge in relation thereto,  other than exchanges
pursuant to Section 2.06, the second  paragraph of Section 3.03 and Section 9.04
not involving any transfer.

         (d) The  Company  shall  not be  required  (i) to  issue,  exchange  or
register the transfer of any Debentures during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of  redemption  of
less than all the  outstanding  Debentures  of the same series and ending at the
close of business on the day of such mailing,  nor (ii) to register the transfer
of or  exchange  any  Debentures  of any series or portions  thereof  called for
redemption.  The provisions of this Section 2.05 are, with respect to any Global
Debenture, subject to Section 2.11 hereof.

         SECTION  2.06.  Temporary   Debentures.   Pending  the  preparation  of
definitive  Debentures of any series,  the Company may execute,  and the Trustee
shall  authenticate  and  make  available  for  delivery,  temporary  Debentures
(printed,  lithographed  or  typewritten)  of any authorized  denomination,  and
substantially in the form of the definitive Debentures in lieu of which they are
issued, but with such omissions, insertions and variations as may be appropriate
for  temporary  Debentures,  all as  may be  determined  by the  Company.  Every
temporary  Debenture  of any series  shall be  executed  by the  Company  and be
authenticated by the Trustee upon the same conditions and in  substantially  the
same manner, and with like effect, as the definitive  Debentures of such series.
Without  unnecessary delay the Company will execute and will furnish  definitive
Debentures of such series and thereupon any or all temporary  Debentures of such
series may be surrendered in exchange  therefor (without charge to the holders),
at the office or agency of the Company designated for the purpose in the Borough
of Manhattan, The City and State of New York, and the Trustee shall authenticate
and such office or agency shall make available for delivery in exchange for such
temporary   Debentures  an  equal  aggregate   principal  amount  of  definitive
Debentures of such series,  unless the Company advises the Trustee to the effect
that  definitive  Debentures  need not be executed and  furnished  until further
notice from the Company.  Until so exchanged,  the temporary  Debentures of such
series shall be entitled to the same benefits under this Indenture as definitive
Debentures of such series authenticated and delivered hereunder.

         SECTION 2.07. Mutilated,  Destroyed, Lost or Stolen Debentures. In case
any temporary or definitive  Debenture  shall become  mutilated or be destroyed,
lost or stolen,  the Company  (subject to the next  succeeding  sentence)  shall
execute,  and  upon  its  request  the  Trustee  (subject  as  aforesaid)  shall
authenticate and make available for delivery, a new Debenture of the same series
bearing a number not contemporaneously outstanding,




                                       15
<PAGE>


in exchange and substitution for the mutilated  Debenture,  or in lieu of and in
substitution for the Debenture so destroyed,  lost or stolen.  In every case the
applicant  for a substituted  Debenture  shall furnish to the Company and to the
Trustee  such  security or  indemnity as may be required by them to save each of
them harmless,  and, in every case of destruction,  loss or theft, the applicant
shall  also  furnish  to the  Company  and  to the  Trustee  evidence  to  their
satisfaction of the destruction,  loss or theft of the applicant's Debenture and
of the ownership  thereof.  The Trustee may  authenticate  any such  substituted
Debenture and make  available for delivery the same upon the written  request or
authorization  of  any  officer  of  the  Company.  Upon  the  issuance  of  any
substituted  Debenture,  the Company may require the payment of a sum sufficient
to cover any tax or other  governmental  charge  that may be imposed in relation
thereto and any other expenses  (including the fees and expenses of the Trustee)
connected  therewith.  In case any  Debenture  which has  matured or is about to
mature shall become mutilated or be destroyed,  lost or stolen, the Company may,
instead of issuing a substitute  Debenture,  pay or authorize the payment of the
same (without surrender thereof except in the case of a mutilated  Debenture) if
the  applicant  for such payment shall furnish to the Company and to the Trustee
such  security or indemnity as they may require to save them  harmless,  and, in
case of destruction,  loss or theft, evidence to the satisfaction of the Company
and the Trustee of the  destruction,  loss or theft of such Debenture and of the
ownership thereof.

         Every  Debenture  issued  pursuant to the provisions of this Section in
substitution  for any Debenture  which is mutilated,  destroyed,  lost or stolen
shall constitute an additional contractual obligation of the Company, whether or
not the mutilated,  destroyed,  lost or stolen  Debenture  shall be found at any
time, or be enforceable by anyone,  and shall be entitled to all the benefits of
this Indenture equally and proportionately  with any and all other Debentures of
the same series duly issued  hereunder.  All Debentures  shall be held and owned
upon the express  condition  that the foregoing  provisions  are exclusive  with
respect to the  replacement or payment of mutilated,  destroyed,  lost or stolen
Debentures,  and shall  preclude (to the extent lawful) any and all other rights
or remedies, notwithstanding any law or statute existing or hereafter enacted to
the  contrary  with  respect  to  the   replacement  or  payment  of  negotiable
instruments or other securities without their surrender.

         SECTION 2.08.  Cancellation of Surrendered  Debentures.  All Debentures
surrendered for the purpose of payment, redemption,  exchange or registration of
transfer  shall, if surrendered to the Company or any paying agent, be delivered
to the Trustee for  cancellation,  or, if surrendered  to the Trustee,  shall be
canceled  by it, and no  Debentures  shall be issued in lieu  thereof  except as
expressly  required or permitted by any of the provisions of this Indenture.  On
written  request of the  Company,  the  Trustee  shall  deliver  to the  Company
canceled  Debentures held by the Trustee. If the Company shall otherwise acquire
any  of the  Debentures,  however,  such  acquisition  shall  not  operate  as a
redemption or  satisfaction of the  indebtedness  represented by such Debentures
unless and until the same are delivered to the Trustee for cancellation.




                                       16

         SECTION 2.09.  Provisions of Indenture and  Debentures for Sole Benefit
of Parties and Debentureholders. Nothing in this Indenture or in the Debentures,
express or implied,  shall give or be construed  to give to any person,  firm or
corporation,  other than the parties  hereto and the holders of the  Debentures,
any legal or  equitable  right,  remedy  or claim  under or in  respect  of this
Indenture, or under any covenant,  condition or provision herein contained;  all
such  covenants,  conditions  and  provisions  being for the sole benefit of the
parties hereto and of the holders of the Debentures.

         SECTION 2.10.  Appointment of  Authenticating  Agent. So long as any of
the Debentures of any series remain  outstanding  there may be an Authenticating
Agent for any or all such series of Debentures  which the Trustee shall have the
right to appoint. Said Authenticating Agent shall be authorized to act on behalf
of the Trustee to  authenticate  Debentures of such series issued upon exchange,
transfer or partial redemption thereof, and Debentures so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if  authenticated  by the Trustee  hereunder.  All references in
this  Indenture to the  authentication  of  Debentures  by the Trustee  shall be
deemed to include  authentication  by an  Authenticating  Agent for such  series
except for  authentication  upon  original  issuance or pursuant to Section 2.07
hereof. Each  Authenticating  Agent shall be acceptable to the Company and shall
be a  corporation  which has a combined  capital and surplus,  as most  recently
reported or  determined  by it,  sufficient  under the laws of any  jurisdiction
under which it is organized or in which it is doing  business to conduct a trust
business,  and which is  otherwise  authorized  under such laws to conduct  such
business  and is  subject  to  supervision  or  examination  by Federal or State
authorities.  If at any time any Authenticating Agent shall cease to be eligible
in accordance with these provisions, it shall resign immediately.

         Any  Authenticating  Agent may at any time  resign  by  giving  written
notice of resignation to the Trustee and to the Company.  The Trustee may at any
time (and  upon  request  by the  Company  shall)  terminate  the  agency of any
Authenticating   Agent  by  giving   written   notice  of  termination  to  such
Authenticating  Agent  and to the  Company.  Upon  resignation,  termination  or
cessation of eligibility of any Authenticating Agent, the Trustee may appoint an
eligible successor Authenticating Agent acceptable to the Company. Any successor
Authenticating Agent, upon acceptance of its appointment hereunder, shall become
vested with all the rights, powers and duties of its predecessor hereunder as if
originally named as an Authenticating Agent pursuant hereto.

         SECTION 2.11.  Global  Debenture.  (a) If the Company  shall  establish
pursuant to Section 2.01 that the  Debentures  of a particular  series are to be
issued as one or more Global Debentures,  then the Company shall execute and the
Trustee shall, in accordance with Section 2.04, authenticate and deliver, one or
more Global Debentures which (i) shall represent, and shall be denominated in an
aggregate  amount  equal  to  the  aggregate  principal  amount  of,  all of the
Outstanding  Debentures of such series,  (ii) shall be registered in the name of
the Depositary or its nominee, (iii) shall be delivered by the




                                       17
<PAGE>


Trustee to the Depositary or pursuant to the  Depositary's  instruction and (iv)
shall bear a legend substantially to the following effect:  "Except as otherwise
provided in Section 2.11 of the Indenture, this Debenture may be transferred, in
whole  but not in  part,  only to  another  nominee  of the  Depositary  or to a
successor Depositary or to a nominee of such successor Depositary."

         (b)   Notwithstanding  the  provisions  of  Section  2.05,  the  Global
Debenture  of a series may be  transferred,  in whole but not in part and in the
manner  provided in Section 2.05,  only to another nominee of the Depositary for
such series,  or to a successor  Depositary for such series selected or approved
by the Company or to a nominee of such successor Depositary.

         (c) If at any time the Depositary  for a series of Debentures  notifies
the Company that it is unwilling  or unable to continue as  Depositary  for such
series  or if at any time the  Depositary  for such  series  shall no  longer be
registered  or in good  standing  under the  Exchange  Act, or other  applicable
statute  or  regulation  and a  successor  Depositary  for  such  series  is not
appointed by the Company  within 90 days after the Company  receives such notice
or becomes aware of such condition,  as the case may be, this Section 2.11 shall
no longer be  applicable  to the  Debentures of such series and the Company will
execute,  and subject to Section 2.05,  the Trustee will  authenticate  and make
available for delivery  Debentures of such series in definitive  registered form
without  coupons,  in authorized  denominations,  and in an aggregate  principal
amount equal to the principal amount of the Global  Debentures of such series in
exchange for such Global  Debenture.  In  addition,  the Company may at any time
determine  that the  Debentures of any series shall no longer be  represented by
one or more Global Debentures and that the provisions of this Section 2.11 shall
no longer apply to the Debentures of such series. In such event the Company will
execute and subject to Section 2.05,  the Trustee,  upon receipt of an Officers'
Certificate  evidencing such determination by the Company, will authenticate and
deliver Debentures of such series in definitive registered form without coupons,
in authorized  denominations,  and in an aggregate principal amount equal to the
principal  amount of the Global  Debentures  of such series in exchange for such
Global  Debentures.  Upon  the  exchange  of  the  Global  Debentures  for  such
Debentures  in  definitive   registered  form  without  coupons,  in  authorized
denominations,  the Global  Debentures  shall be canceled by the  Trustee.  Such
Debentures  in  definitive  registered  form issued in  exchange  for the Global
Debentures  pursuant to this Section  2.11(c)  shall be registered in such names
and in such authorized denominations as the Depositary, pursuant to instructions
from its direct or  indirect  participants  or  otherwise,  shall  instruct  the
Trustee.  The Trustee  shall  deliver  such  Debentures  to the  Depositary  for
delivery to the persons in whose names such Debentures are so registered.

         SECTION 2.12. CUSIP Numbers.  The Company in issuing the Debentures may
use "CUSIP" and "CINS" numbers (if then generally in use), and the Trustee shall
use CUSIP numbers or CINS numbers,  as the case may be, in notices of redemption
or




                                       18
<PAGE>


exchange as a convenience to  Debentureholders  and no  representation  shall be
made as to the  correctness  of such numbers either as printed on the Debentures
or as contained in any notice of redemption or exchange.


                                    ARTICLE 3
              REDEMPTION OF DEBENTURES AND SINKING FUND PROVISIONS

         SECTION  3.01.  Redemption  of  Debentures.  The Company may redeem the
Debentures  of any  series  issued  hereunder  on and  after  the  dates  and in
accordance  with the terms  established for such series pursuant to Section 2.01
hereof.

         SECTION  3.02.  Notice of  Redemption.  (a) In case the  Company  shall
desire to exercise such right to redeem all or, as the case may be, a portion of
the Debentures of any series in accordance  with the right reserved so to do, it
shall give notice of such redemption to holders of the Debentures of such series
to be  redeemed  by  mailing,  first  class  postage  prepaid,  a notice of such
redemption not less than 30 days and not more than 60 days before the date fixed
for  redemption  of that series to such holders at their last  addresses as they
shall  appear upon the  Debenture  Register.  Any notice  which is mailed in the
manner herein provided shall be  conclusively  presumed to have been duly given,
whether or not the registered holder receives the notice.  In any case,  failure
duly to give such notice to the holder of any Debenture of any series designated
for  redemption  in whole or in part,  or any  defect in the  notice,  shall not
affect  the  validity  of the  proceedings  for  the  redemption  of  any  other
Debentures of such series or any other series.  In the case of any redemption of
Debentures  prior  to the  expiration  of any  restriction  on  such  redemption
provided in the terms of such  Debentures  or elsewhere in this  Indenture,  the
Company  shall  furnish the Trustee  with an  Officers'  Certificate  evidencing
compliance with any such restriction.

         Each  such  notice  of  redemption  shall  specify  the date  fixed for
redemption and the redemption price at which Debentures of that series are to be
redeemed,  and  shall  state  that  payment  of the  redemption  price  of  such
Debentures to be redeemed will be made at the office or agency of the Company in
the Borough of Manhattan,  the City and State of New York, upon presentation and
surrender  of such  Debentures,  that  interest  accrued  to the date  fixed for
redemption  will be paid as specified  in said notice,  that from and after said
date  interest  will  cease to accrue and that the  redemption  is for a sinking
fund, if such is the case. If less than all the Debentures of a series are to be
redeemed,  the notice to the holders of Debentures of that series to be redeemed
in whole or in part shall specify the
particular Debentures to be so redeemed. In case any Debenture is to be redeemed
in part only, the notice which relates to such Debenture shall state the portion
of the  principal  amount  thereof to be  redeemed,  and shall state that on and
after the redemption date,





                                       19
<PAGE>


upon surrender of such  Debenture,  a new Debenture or Debentures of such series
in principal amount equal to the unredeemed portion thereof will be issued.

         (b) If less than all the Debentures of a series are to be redeemed, the
Company  shall give the Trustee at least 45 days'  notice in advance of the date
fixed for redemption as to the aggregate  principal  amount of Debentures of the
series to be redeemed, and thereupon the Trustee shall select, by lot or in such
other manner as it shall deem  appropriate  and fair in its discretion and which
may provide  for the  selection  of a portion or  portions  (equal to $50 or any
integral  multiple  thereof) of the  principal  amount of such  Debentures  of a
denomination larger than $50, the Debentures to be redeemed and shall thereafter
promptly  notify the Company in writing of the numbers of the  Debentures  to be
redeemed, in whole or in part.

         The  Company  may, if and  whenever  it shall so elect,  by delivery of
instructions  signed  on its  behalf  by its  President  or any Vice  President,
instruct  the  Trustee  or any  paying  agent  to  call  all or any  part of the
Debentures  of a  particular  series  for  redemption  and  to  give  notice  of
redemption  in the manner set forth in this  Section,  such  notice to be in the
name of the Company or its own name as the Trustee or such paying agent may deem
advisable.  In any  case in which  notice  of  redemption  is to be given by the
Trustee or any such  paying  agent,  the  Company  shall  deliver or cause to be
delivered to, or permit to remain with, the Trustee or such paying agent, as the
case may be,  such  Debenture  Register,  transfer  books or other  records,  or
suitable copies or extracts therefrom,  sufficient to enable the Trustee or such
paying  agent  to give  any  notice  by mail  that  may be  required  under  the
provisions of this Section.

         SECTION 3.03.  Debentures Due and Payable.  (a) If the giving of notice
of redemption  shall have been  completed as above  provided,  the Debentures or
portions of  Debentures  of the series to be redeemed  specified  in such notice
shall  become due and payable on the date and at the place stated in such notice
at the applicable  redemption price,  together with interest accrued to the date
fixed for redemption  and interest on such  Debentures or portions of Debentures
shall  cease to accrue on and after the date  fixed for  redemption,  unless the
Company  shall  default in the  payment  of such  redemption  price and  accrued
interest with respect to any such Debenture or portion thereof.  On presentation
and surrender of such  Debentures  on or after the date fixed for  redemption at
the place of payment specified in the notice,  said Debentures shall be paid and
redeemed at the  applicable  redemption  price for such  series,  together  with
interest accrued thereon to the date fixed for redemption (but if the date fixed
for redemption is an Interest Payment Date, the interest  installment payable on
such date shall be payable to the registered  holder at the close of business on
the applicable record date pursuant to Section 2.03).

         (b) Upon  presentation  of any  Debenture of such series which is to be
redeemed  in  part  only,  the  Company  shall  execute  and the  Trustee  shall
authenticate  and the office or



                                       20
<PAGE>

agency where the Debenture is presented shall make available for delivery to the
holder thereof,  at the expense of the Company, a new Debenture or Debentures of
the same series,  of authorized  denominations  in principal amount equal to the
unredeemed portion of the Debenture so presented.

         SECTION 3.04. Sinking Funds for Debentures.  The provisions of Sections
3.04,  3.05 and 3.06 shall be applicable to any sinking fund for the  retirement
of  Debentures of a series,  except as otherwise  specified as  contemplated  by
Section 2.01 for Debentures of such series.

         The minimum  amount of any sinking  fund  payment  provided  for by the
terms of Debentures of any series is herein referred to as a "mandatory  sinking
fund payment",  and any payment in excess of such minimum amount provided for by
the terms of  Debentures  of any series is herein  referred  to as on  "optional
sinking  fund  payment".  If  provided  for by the terms of  Debentures  for any
series,  the cash amount of any sinking fund payment may be subject to reduction
as provided in Section  3.05.  Each sinking fund payment shall be applied to the
redemption  of  Debentures  of any  series  as  provided  for by  the  terms  of
Debentures of such series.

         SECTION 3.05.  Satisfaction  of Sinking Fund Payments With  Debentures.
The Company (i) may deliver  outstanding  Debentures of a series (other than any
previously called for redemption) and (ii) may apply as a credit Debentures of a
series which have been redeemed  either at the election of the Company  pursuant
to the terms of such Debentures or through the application of permitted optional
sinking fund payments pursuant to the terms of such Debentures,  in each case in
satisfaction  of all or any part of any sinking fund payment with respect to the
Debentures  of such  series  required  to be made  pursuant to the terms of such
Debentures  as  provided  for by the terms of such  series;  provided  that such
Debentures  have not been  previously  so  credited.  Such  Debentures  shall be
received and credited  for such purpose by the Trustee at the  redemption  price
specified in such  Debentures  for redemption  through  operation of the sinking
fund and the amount of such sinking fund payment shall be reduced accordingly.

         SECTION 3.06.  Redemption of Debentures for Sinking Fund. Not less than
45 days prior to each sinking  fund  payment date for any series of  Debentures,
the Company will deliver to the Trustee an Officers' Certificate  specifying the
amount of the next ensuing  sinking fund payment for that series pursuant to the
terms for that series, the portion thereof,  if any, which is to be satisfied by
delivering and crediting  Debentures of that series pursuant to Section 3.05 and
the basis for such credit and will,  together with such  Officers'  Certificate,
deliver to the Trustee any Debentures to be so delivered.  Not less than 30 days

                       PARTICULAR COVENANTS OF THE COMPANY

The Company covenants and agrees for each series of the Debentures as follows:

         SECTION  4.01.  Payment  of  Principal  of (And  Premium,  if any)  and
Interest on Debentures.  The Company will duly and punctually pay or cause to be

established with respect to such Debentures.

         SECTION 4.02. Maintenance of Office or Agent for Payment of Debentures,
Designation of Office or Agency for Payment, Registration, Transfer and Exchange
of Debentures.  So long as any series of the Debentures remain outstanding,  the
Company agrees to maintain an office or agency in the Borough of Manhattan,  The
City and State of New York,  with  respect to each such series and at such other
location or locations  as may be  designated  as provided in this Section  4.02,
where  (i)  Debentures  of  that  series  may be  presented  for  payment,  (ii)
Debentures  of that  series may be  presented  as herein  above  authorized  for
registration of transfer and exchange,  and (iii) notices and demands to or upon
the Company in respect of the  Debentures of that series and this  Indenture may
be given or served,  such designation to continue with respect to such office or
agency until the Company  shall,  by written notice signed by its President or a
Vice  President  and  delivered to the Trustee,  designate  some other office or
agency for such  purposes or any of them.  If at any time the Company shall fail
to  maintain  any such  required  office or agency or shall fail to furnish  the
Trustee with the address thereof, such presentations, notices and demands may be
made or served at the  Corporate  Trust Office of the  Trustee,  and the Company
hereby  appoints  the  Trustee as its agent to receive  all such  presentations,
notices and demands.

         SECTION 4.03.  Duties of Paying Agent;  Company as Payment  Agent;  and
Holding  Sums of Trust.  (a) If the  Company  shall  appoint  one or more paying
agents for all or any series of the  Debentures,  other  than the  Trustee,  the
Company will cause each such paying agency to execute and deliver to the Trustee
an instrument  in which such agent shall agree with the Trustee,  subject to the
provisions of this Section:


                  (1) that it will  hold all sums  held by it as such  agent for
                  the  payment  of the  principal  of (and  premium,  if any) or
                  interest on the  Debentures of that series  (whether such sums
                  have been paid to it by the Company or by any


                                       22
<PAGE>


                  other obligor of such  Debentures) in trust for the benefit of
                  the persons entitled thereto:

                  (2)  that it will  give  the  Trustee  written  notice  of any
                  failure  by the  Company  (or by any  other  obligor  of  such
                  Debentures)  to make  any  payment  of the  principal  of (and
                  premium,  if any) or interest on the Debentures of that series
                  when the same shall be due and payable;

                  (3) that it will,  at any time during the  continuance  of any
                  failure  referred to in the preceding  paragraph (a)(2) above,
                  upon the written request of the Trustee,  forthwith pay to the
                  Trustee all sums so held in trust by such paying agent; and

                  (4) that it will  perform all other  duties of paying agent as
                  set forth in this Indenture.

         (b) If the Company  shall act as its own paying  agent with  respect to
any  series  of the  Debentures,  it  will on or  before  each  due  date of the
principal of (and premium, if any) or interest on Debentures of that series, set
aside,  segregate  and hold in trust for the  benefit  of the  persons  entitled
thereto a sum sufficient to pay such principal (and premium, if any) or interest
so becoming  due on  Debentures  of that series until such sums shall be paid to
such  persons or  otherwise  disposed of as herein  provided  and will  promptly
notify in writing the Trustee of such action, or any failure (by it or any other
obligor on such Debentures) to take such action. Whenever the Company shall have
one or more paying agents for any series of Debentures,  it will,  prior to each
due date of the principal of (and premium, if any) or interest on any Debentures
of that  series,  deposit  with the  paying  agent a sum  sufficient  to pay the
principal (and premium, if any) or interest so becoming due, such sum to be held
in trust for the benefit of the persons  entitled to such principal,  premium or
interest,  and  (unless  such paying  agent is the  Trustee)  the  Company  will
promptly notify the Trustee of its action or failure so to act.

         (c) Anything in this Section to the contrary  notwithstanding,  (i) the
agreement  to hold sums in trust as provided  in this  Section is subject to the
provisions  of Section  11.04,  and (ii) the  Company  may at any time,  for the
purpose of obtaining the satisfaction and discharge of this Indenture or for any
other  purpose,  pay, or direct any paying agent to pay, to the Trustee all sums
held in trust by the Company or such paying  agent,  such sums to be held by the
Trustee  upon the same terms and  conditions  as those upon which such sums were
held by the Company or such paying  agent;  and, upon such payment by any paying
agent to the  Trustee,  such paying  agent  shall be  released  from all further
liability with respect to such money.

         SECTION  4.04.  Appointment  to Fill Vacancy in Office of Trustee.  The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the




                                       23

manner provided in Section 7.10, a Trustee,  so that there shall at all times be

       DEBENTUREHOLDER'S LISTS AND REPORTS BY THE COMPANY AND THE TRUSTEE

         SECTION 5.01.  Company to Furnish  Trustee  Information as to Names and
Addresses  of  Debentures.  The Company will furnish or cause to be furnished to
the Trustee (a) on a quarterly  basis on each regular record date (as defined in
Section 2.03) a list, in such form as the Trustee may reasonably require, of the
names and  addresses  of the  holders of each  series of  Debentures  as of such
regular  record  date,  provided,  that the Company  shall not be  obligated  to
furnish or cause to furnish such list at any time that the list shall not differ
in any respect from the most recent list furnished to the Trustee by the Company
and (b) at such other times as the Trustee may request in writing within 30 days
after the receipt by the Company of any such request, a list of similar form and
content  as of a date not more  than 15 days  prior  to the  time  such  list is
furnished;  provided, however, no such list need be furnished for any series for
which the Trustee shall be the Debenture Registrar.

         SECTION 5.02. Trustee to Preserve Information as to Names and Addresses
of Debentureholders.  (a) The Trustee shall preserve, in as current a form as is
reasonably  practicable,  all  information  as to the names and addresses of the
holders of  Debentures  contained  in the most  recent list  furnished  to it as
provided  in  Section  5.01 and as to the  names and  addresses  of  holders  of
Debentures  received by the Trustee in its capacity as Debenture  Registrar  (if
acting in such capacity).

         (b) The Trustee may  destroy  any list  furnished  to it as provided in
Section 5.01 upon receipt of a new list so furnished.

         (c)  In  case  three  or  more  holders  of   Debentures  of  a  series
(hereinafter  referred to as "applicants") apply in writing to the Trustee,  and
furnish to the Trustee  reasonable  proof that each such  applicant  has owned a
Debenture  for a  period  of at  least  six  months  preceding  the date of such
application,   and  such  application  states  that  the  applicants  desire  to
communicate  with other  holders of  Debentures of such series or holders of all
Debentures  with  respect to their  rights  under this  Indenture  or under such
Debentures,  and is  accompanied  by a copy  of  the  form  of  proxy  or  other
communication which such applicants propose to transmit,  then the Trustee shall
within  five  business  days  after  the  receipt  of such  application,  at its
election, either:





                                       24
<PAGE>


                  (1)  afford  to  such  applicants  access  to the  information
                  preserved  at the time by the Trustee in  accordance  with the
                  provisions of subsection (a) of this Section 5.02; or

                  (2) inform such  applicants  as to the  approximate  number of
                  holders of Debentures of such series or of all Debentures,  as
                  the case may be,  whose  names  and  addresses  appear  in the
                  information   preserved  at  the  time  by  the  Trustee,   in
                  accordance  with  the  provisions  of  subsection  (a) of this
                  Section  5.02,  and as to the  approximate  cost of mailing to
                  such   Debentureholders   the   form   of   proxy   or   other
                  communication, if any, specified in such application.

         (d) If the Trustee shall elect not to afford such applicants  access to
such  information,   the  Trustee  shall,  upon  the  written  request  of  such
applicants, mail to each holder of such series or of all Debentures, as the case
may be, whose name and address appears in the information  preserved at the time
by the Trustee in  accordance  with the  provisions  of  subsection  (a) of this
Section  5.02,  a copy of the  form of proxy  or  other  communication  which is
specified in such  request,  with  reasonable  promptness  after a tender to the
Trustee  of the  material  to be mailed and of  payment,  or  provision  for the
payment,  of the reasonable  expenses of mailing,  unless within five days after
such  tender,  the  Trustee  shall  mail to such  applicants  and file  with the
Securities and Exchange Commission (the  "Commission"),  together with a copy of
the  material  to be mailed,  a written  statement  to the effect  that,  in the
opinion of the Trustee,  such mailing would be contrary to the best interests of
the holders of Debentures of such series or of all  Debentures,  as the case may
be, or would be in violation of  applicable  law. Such written  statement  shall
specify the basis of such opinion.  If the Commission,  after  opportunity for a
hearing upon the objections  specified in the written statement so filed,  shall
enter an order refusing to sustain any of such objections or if, after the entry
of an order  sustaining one or more of such  objections,  the  Commission  shall
find,  after notice and  opportunity  for hearing,  that all the  objections  so
sustained have been met and shall enter an order so declaring, the Trustee shall
mail  copies  of such  material  to all such  Debentureholders  with  reasonable
promptness  after  the  entry of such  order  and the  renewal  of such  tender;
otherwise,  the  Trustee  shall be relieved  of any  obligation  or duty to such
applicants respecting their application.

         (e) Each and every holder of the  Debentures,  by receiving and holding
the same,  agrees with the Company and the Trustee  that neither the Company nor
the  Trustee  nor any paying  agent nor any  Debenture  Registrar  shall be held
accountable by reason of the disclosure of any such  information as to the names
and addresses of the holders of Debentures in accordance  with the provisions of
subsection  (b) of this  Section,  regardless  of the  source  from  which  such
information was derived,  and that the Trustee shall not be held  accountable by
reason of mailing any material  pursuant to a request made under said subsection
(b).

                  been  or is to be  withheld  by  it  in  accordance  with  the
                  provisions of Section 6.07.

         (b) The Trustee shall transmit by mail, first class postage prepaid, to
the  Debentureholders,  as their names and  addresses  appear upon the Debenture
Register,  a brief  report  with  respect  to the  character  and  amount of any
advances (and if the Trustee elects so to state, the  circumstances  surrounding
the  making  thereof)  made by the  Trustee  as such  since the date of the last

of this Indenture), for the reimbursement of which it claims or may claim a lien
or charge  prior to that of the  Debentures  of any series on  property or funds
held or collected  by it as Trustee,  and which it has not  previously  reported

outstanding  at such time,  such report to be  transmitted  within 90 days after
such time.

         (c) A copy of each such report shall, at the time of such  transmission
to Debentureholders,  be filed by the Trustee with the Company,  with each stock
exchange upon which any  Debentures  are listed (if so listed) and also with the
Commission.  The Company agrees to notify the Trustee when any Debentures become

                  bankrupt  or  insolvent,  or  approving  as  properly  filed a
                  petition seeking  liquidation or reorganization of the Company
                  under  the  Federal  Bankruptcy  Code  or  any  other  similar
                  applicable  Federal  or State  law,  and such  decree or order
                  shall have continued unvacated and unstayed for a period of 90
                  days;  or an  involuntary  case shall be commenced  under such
                  Code in respect of the Company and shall continue  undismissed
                  for a period  of 90 days or an order  for  relief in such case
                  shall  have  been  entered;  or a  decree  or order of a court
                  having  jurisdiction  in the premises  shall have been entered

         (b) In each and  every  such  case,  unless  the  principal  of all the
Debentures of that series shall have already become due and payable,  either the
Trustee or the holders of not less than 25% in aggregate principal amount of the
Debentures of that series then  outstanding  hereunder,  by notice in writing to
the Company (and to the Trustee if given by such Debentureholders),  may declare
the  principal  of all the  Debentures  of  that  series  to be due and  payable
immediately,  and upon any such  declaration  the same shall become and shall be
immediately  due and payable,  anything  contained  in this  Indenture or in the
Debentures of that series or established with respect to that series pursuant to
Section 2.01 hereof to the contrary notwithstanding.

         (c) Section 6.01(b),  however,  is subject to the condition that if, at
any time after the principal of the Debentures of that series shall have been so
declared due and  payable,  and before any judgment or decree for the payment of
the moneys due shall have been obtained or entered as hereinafter provided,  the
Company shall pay or shall deposit with the Trustee a sum  sufficient to pay all
matured  installments of interest upon all the Debentures of that series and the
principal of (and  premium,  if any, on) any and all  Debentures  of that series
which shall have become due otherwise than by  acceleration  (with interest upon
such  principal  and  premium,  if any,  and, to the extent that such payment is
enforceable under applicable law, upon overdue installments of interest,  at the
rate per annum  expressed in the  Debentures  of that series to the date of such
payment or deposit) and the amount  payable to the Trustee  under  Section 7.06,
and any and all  defaults  under the  Indenture,  other than the  nonpayment  of
principal on  Debentures of that series which shall not have become due by their
terms,  shall have been  remedied or waived as provided in Section 6.06 then and
in every such case the holders of a majority in  aggregate  principal  amount of
the Debentures of that series then  outstanding  (subject to, in the case of any
series of  Debentures  held as trust  assets of a AES Trust and with  respect to
which a Security  Exchange  has not  theretofore  occurred,  such consent of the
holders of the Preferred  Securities and the Common Securities of such AES Trust
as may be required under the Declaration of Trust of such AES Trust), by written
notice to the Company and to the Trustee, may rescind and annul such declaration
and its  consequences  with  respect to that series of  Debentures;  but no such
rescission and annulment shall extend to or shall affect any subsequent default,
or shall impair any right consequent thereon.

         (d) In case the Trustee shall have  proceeded to enforce any right with
respect to Debentures of that series under this  Indenture and such  proceedings
shall  have  been  discontinued  or  abandoned  because  of such  rescission  or
annulment or for any other reason or shall have been determined adversely to the
Trustee,  then and in every  such  case the  Company  and the  Trustee  shall be
restored  respectively to their former positions and rights  hereunder,  and all
rights,  remedies  and powers of the Company and the Trustee  shall  continue as
though no such proceedings had been taken.

         (e) If, prior to a Security  Exchange with respect to the Debentures of
any series,  a Default with respect to the  Debentures of such series shall have
occurred,  the Company  expressly  acknowledges that under the circumstances set
forth in the applicable Declaration of Trust, any holder of Preferred Securities
of the  applicable  AES Trust may  enforce  directly  against  the  Company  the
applicable Property Trustee's rights hereunder.  In furtherance of the foregoing
and for the avoidance of any doubt,  the Company  acknowledges  that,  under the
circumstances  described in the applicable Declaration of Trust, any such holder
of Preferred  Securities,  in its own name,  in the name of the  applicable  AES
Trust or in the name of the holders of the Preferred  Securities  issued by such
AES Trust,  may  institute or cause to be  instituted a  proceeding,  including,
without  limitation,  any suit in equity,  an action at law or other judicial or
administrative  proceeding,  to enforce the applicable Property Trustee's rights
hereunder  directly  against the Company as issuer of the  applicable  series of
Debentures,  and may prosecute such proceeding to judgment or final decree,  and
enforce the same against the Company.

         SECTION 6.02. Covenant of Company to Pay to Trustee Whole Amount Due on
Debentures  on Default in Payment of Interest or  Principal  (and  Premiums,  if
any).  (a) The Company  covenants  that (1) in case default shall be made in the
payment of any installment of interest on any of the Debentures of a series,  or
any payment  required by any sinking or analogous fund  established with respect
to that series as and when the same shall have become due and payable,  and such
default shall have  continued  for a period of 10 business  days, or (2) in case
default  shall be made in the payment of the  principal of (or premium,  if any,
on) any of the  Debentures  of a series  when the same shall have become due and
payable,  whether upon maturity of the Debentures of a series or upon redemption
or upon declaration or otherwise,  then, upon demand of the Trustee, the Company
will pay to the  Trustee,  for the benefit of the holders of the  Debentures  of
that series, the whole amount that then shall have become due and payable on all
such Debentures for principal (and premium, if any) or interest, or both, as the
case may be, with interest upon the overdue principal (and premium,  if any) and
(to the extent that payment of such interest is enforceable under applicable law
and  without  duplication  of any  other  amounts  paid  by the  Company  or the
applicable AES Trust in respect  thereof) upon overdue  installments of interest
at the rate per annum  expressed  in the  Debentures  of that  series;  and,  in
addition thereto,  such further amount as shall be sufficient to cover the costs
and expenses of collection,  and the amount payable to the Trustee under Section
7.06.

         (b) In case the Company  shall fail  forthwith to pay such amounts upon
such demand,  the Trustee,  in its own name and as trustee of an express  trust,
shall be entitled and empowered to institute any action or proceedings at law or
in equity for the  collection  of the sums so due and unpaid,  and may prosecute
any such action or proceeding  to judgment or final decree,  and may enforce any
such  judgment or final  decree  against the Company or other  obligor  upon the
Debentures of that series and collect in the manner




                                       31
<PAGE>


provided by law out of the  property of the  Company or other  obligor  upon the
Debentures of that series wherever situated the moneys adjudged or decreed to be
payable.

         (c) In case of any receivership,  insolvency, liquidation,  bankruptcy,
reorganization,   readjustment,   arrangement,  composition  or  other  judicial
proceedings affecting the Company, any other obligor on such Debentures,  or the
creditors or property of either,  the Trustee  shall have the power to intervene
in such  proceedings  and take any action  therein  that may be permitted by the
court and shall (except as may be otherwise provided by law) be entitled to file
such  proofs of claim and other  papers and  documents  as may be  necessary  or
advisable  in order to have the  claims of the  Trustee  and of the  holders  of
Debentures  of such series  allowed for the entire amount due and payable by the
Company or such other obligor under the Indenture at the date of  institution of
such proceedings and for any additional  amount which may become due and payable
by the Company or such other obligor after such date, and to collect and receive
any moneys or other property  payable or  deliverable on any such claim,  and to
distribute  the same after the  deduction  of the amount  payable to the Trustee
under  Section  7.06;  and any  receiver,  assignee or trustee in  bankruptcy or
reorganization is hereby authorized by each of the holders of Debentures of such
series to make such payments to the Trustee,  and, in the event that the Trustee
shall consent to the making of such payments directly to such  Debentureholders,
to pay to the Trustee any amount due it under Section 7.06.

         (d) All rights of action and of asserting  claims under this Indenture,
or under any of the terms established with respect to Debentures of that series,
may be enforced by the Trustee without the possession of any of such Debentures,
or the production thereof at any trial or other proceeding relative thereto, and
any such suit or  proceeding  instituted  by the Trustee shall be brought in its
own name as trustee of an express  trust,  and any  recovery of judgment  shall,
after  provision  for payment to the  Trustee of any  amounts due under  Section
7.06,  be for the  ratable  benefit  of the  holders of the  Debentures  of such
series.

         In case of an  Event  of  Default  hereunder,  the  Trustee  may in its
discretion  proceed  to protect  and  enforce  the  rights  vested in it by this
Indenture by such  appropriate  judicial  proceedings  as the Trustee shall deem
most  effectual to protect and enforce any of such  rights,  either at law or in
equity or in bankruptcy or otherwise,  whether for the specific  enforcement  of
any covenant or agreement  contained in the  Indenture or in aid of the exercise
of any power  granted  in this  Indenture,  or to  enforce  any  other  legal or
equitable right vested in the Trustee by this Indenture or by law.

         Nothing  herein  contained  shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any  Debentureholder any
plan of  reorganization,  arrangement,  adjustment or composition  affecting the
Debentures  of that series or the rights of any holder  thereof or to  authorize
the Trustee to vote in respect of the claim of any  Debentureholder  in any such
proceeding.

         SECTION 6.03.  Application of Moneys  Collected by Trustee.  Any moneys
collected  by the Trustee  pursuant to Section 6.02 with respect to a particular
series of  Debentures  shall be applied in the order  following,  at the date or
dates fixed by the Trustee  and, in case of the  distribution  of such moneys on
account of principal (or premium, if any) or interest,  upon presentation of the
several  Debentures of that series,  and stamping  thereon the payment,  if only
partially paid, and upon surrender thereof if fully paid:

                  FIRST:  To the payment of costs and expenses of collection and
                  of all amounts payable to the Trustee under Section 7.06; and

                  SECOND: To the payment of the amounts then due and unpaid upon
                  Debentures of such series for principal (and premium,  if any)
                  and interest,  in respect of which or for the benefit of which
                  such money has been collected,  ratably, without preference or
                  priority of any kind, according to the amounts due and payable
                  on such  Debentures  for principal  (and premium,  if any) and
                  interest, respectively.

         SECTION 6.04.  Limitation on Suits by Holders of Debentures.  No holder
of any  Debenture of any series shall have any right by virtue or by availing of
any provision of this  Indenture to institute any suit,  action or proceeding in
equity  or at law upon or under or with  respect  to this  Indenture  or for the
appointment of a receiver or trustee, or for any other remedy hereunder,  unless
such  holder  previously  shall have given to the Trustee  written  notice of an
Event of Default and of the  continuance  thereof with respect to  Debentures of
such series  specifying  such Event of Default,  as hereinbefore  provided,  and
unless also the holders of not less than 25% in  aggregate  principal  amount of
the Debentures of such series then  outstanding  shall have made written request
upon the Trustee to institute such action, suit or proceeding in its own name as
trustee  hereunder  and  shall  have  offered  to the  Trustee  such  reasonable
indemnity as it may require  against the costs,  expenses and  liabilities to be
incurred  therein or  thereby,  and the Trustee for 60 days after its receipt of
such notice, request and offer of indemnity,  shall have failed to institute any
such action,  suit or proceeding;  it being  understood and intended,  and being
expressly  covenanted by the taker and holder of every  Debenture of such series
with every other such taker and holder and Trustee,  that no one or more holders
of  Debentures  of such series shall have any right in any manner  whatsoever by
virtue or by availing of any provision of this  Indenture to affect,  disturb or
prejudice  the  rights of the  holders  of any other of such  Debentures,  or to
obtain or seek to obtain  priority  over or preference to any other such holder,
or to enforce  any right  under  this  Indenture,  except in the  manner  herein
provided  and for the  equal,  ratable  and  common  benefit  of all  holders of
Debentures of such series.  For the protection and enforcement of the provisions
of this  Section,  each  and  every  Debentureholder  and the  Trustee  shall be
entitled to such relief as can be given either at law or in equity.






                                       33

         Notwithstanding  any other provisions of this Indenture,  however,  the
right of any holder of any Debenture to receive payment of the principal of (and
premium,  if any) and interest on such  Debenture,  as therein  provided,  on or
after the  respective  due dates  expressed in such Debenture (or in the case of
redemption, on the redemption date), or to institute suit for the enforcement of
any such payment on or after such respective dates or redemption date, shall not
be impaired or affected without the consent of such holder.

         SECTION  6.05.  Remedies  Cumulative;  Delay or Omission in Exercise of
Rights Not Waiver of Default.  (a) All powers and remedies given by this Article
to the Trustee or to the Debentureholders shall, to the extent permitted by law,
be deemed  cumulative  and not  exclusive of any others  thereof or of any other
powers and remedies  available to the Trustee or the holders of the  debentures,
by judicial  proceedings or otherwise,  to enforce  performance or observance of
the  covenants  and   agreements   contained  in  this  Indenture  or  otherwise
established with respect to such Debentures.

         (b) No delay or  omission of the Trustee or of any holder of any of the
Debentures  to exercise  any right or power  accruing  upon any Event of Default
occurring and continuing as aforesaid  shall impair any such right or power,  or
shall  be  construed  to be a  waiver  of any such  default  or an  acquiescence
therein;  and, subject to the provisions of Section 6.04, every power and remedy
given by this Article or by law to the Trustee or to the Debentureholders may be
exercised from time to time, and as often as shall be deemed  expedient,  by the
Trustee or by the Debentureholders.

         SECTION  6.06.  Rights of Holders of  Majority in  Principal  Amount of
Debentures to Direct Trustee and to Waive Defaults. The holders of a majority in
aggregate  principal  amount  of the  Debentures  of  any  series  at  the  time
outstanding,  determined in accordance  with Section 8.04 (with,  in the case of
any series of Debentures held as trust assets of a AES Trust and with respect to
which a Security Exchange has not theretofore occurred,  such consent of holders
of the Preferred  Securities and the Common  Securities of such AES Trust as may
be required under the  Declaration  of Trust of such AES Trust),  shall have the
right to direct the time,  method and place of conducting any proceeding for any
remedy  available to the Trustee,  or exercising any trust or power conferred on
the Trustee with respect to such series; provided,  however, that such direction
shall not be in conflict  with any rule of law or with this  Indenture or unduly
prejudicial  to the rights of holders of  Debentures  of any other series at the
time outstanding determined in accordance with Section 8.04 not parties thereto.
Subject to the  provisions of Section 7.01,  the Trustee shall have the right to
decline to follow any such  direction if the Trustee in good faith  shall,  by a
Responsible Officer or Officers of the Trustee, determine that the proceeding so
directed  would  involve  the Trustee in  personal  liability.  The holders of a
majority in aggregate  principal  amount of the  Debentures of any series at the
time outstanding  affected  thereby,  determined in accordance with section 8.04
(with,  in the case of any series of  Debentures  held as trust  assets of a AES
Trust  and  with  respect  to  which a  Security  Exchange  has not  theretofore
occurred, such consent of holders of the Preferred



                                       34
<PAGE>


Securities and the Common  Securities of such AES Trust as may be required under
the Declaration of Trust of such AES Trust), may on behalf of the holders of all
of the  Debentures of such series waive any past default in the  performance  of
any of the covenants  contained  herein or established  pursuant to section 2.01
with  respect  to such  series  and its  consequences,  except a default  in the
payment of the  principal  of, or premium,  if any,  or interest  on, any of the
Debentures  of that series as and when the same shall become due by the terms of
such  Debentures  otherwise than by  acceleration  (unless such default has been
cured and a sum  sufficient  to pay all matured  installments  of  interest  and
principal  and any premium has been  deposited  with the Trustee (in  accordance
with Section  6.01(c)) or a call for  redemption  of  Debentures of that series.
Upon any such waiver,  the default  covered  thereby shall be deemed to be cured
for all purposes of this Indenture and the Company,  the Trustee and the holders
of the Debentures of such series shall be restored to their former positions and
rights  hereunder,  respectively;  but  no  such  waiver  shall  extend  to  any
subsequent or other default or impair any right consequent thereon.

         SECTION 6.07.  Trustee to Give Notice of Defaults  Known To It, But May
Withhold in Certain  Circumstances.  The Trustee shall, within 90 days after the
occurrence of a default with respect to a particular  series,  transmit by mail,
first class postage  prepaid,  to the holders of  Debentures of that series,  as
their names and  addresses  appear upon the  Debenture  Register,  notice of all
defaults with respect to that series known to the Trustee,  unless such defaults
shall have been cured before the giving of such notice (the term  "defaults" for
the purposes of this Section being hereby defined to be the events  specified in
subsections  (1),  (2), (3), (4) and (5) of Section  6.01(a),  not including any
periods of grace provided for therein and  irrespective  of the giving of notice
provided for by subsection (3) of Section  6.01(a));  provided,  that, except in
the case of default in the payment of the  principal of (or premium,  if any) or
interest  on any of the  Debentures  of that  series  or in the  payment  of any
sinking fund installment  established  with respect to that series,  the Trustee
shall be  protected  in  withholding  such notice if and so long as the board of
directors,  the executive  committee,  or a trust committee of directors  and/or
Responsible   Officers,  of  the  Trustee  in  good  faith  determine  that  the
withholding  of such notice is in the  interests of the holders of Debentures of
that series;  provided further, that in the case of any default of the character
specified in Section  6.01(a)(3)  with respect to  Debentures  of such series no
such notice to the holders of the Debentures of that series shall be given until
at least 30 days after the occurrence thereof.

         The  Trustee  shall  not be deemed to have  knowledge  of any  default,
except (i) a default under  subsection  (a)(1) or (a)(2) of Section 6.01 as long
as the Trustee is acting as paying agent for such series of  Debentures  or (ii)
any  default as to which the Trustee  shall have  received  written  notice or a
Responsible Officer charged with the administration of this Indenture shall have
obtained written notice.

         SECTION 6.08.  Requirements  of an  Undertaking to Pay Costs in Certain
Suits Under Indenture or Against  Trustee.  All parties to this Indenture agree,
and each holder of any  Debentures  by his or her  acceptance  thereof  shall be
deemed to have agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture,  or in any suit
against the Trustee for any action taken or omitted by it as Trustee, the filing
by any party  litigant in such suit of an  undertaking  to pay the costs of such
suit,  and that  such  court  may in its  discretion  assess  reasonable  costs,
including  reasonable  attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party  litigant;  but the provisions of this Section shall not apply to any
suit instituted by the Trustee,  to any suit instituted by any  Debentureholder,
or group of  Debentureholders,  holding  more  than 10% in  aggregate  principal
amount of the outstanding Debentures of any series, or to any suit instituted by
any  Debentureholder  for the enforcement of the payment of the principal of (or
premium,  if any) or interest on any  Debenture of such series,  on or after the
respective due dates expressed in such Debenture or established pursuant to this
Indenture.

                             CONCERNING THE TRUSTEE

         SECTION 7.01. Upon Event of Default  Occurring and Continuing,  Trustee
Shall  Exercise  Powers  Vested In It, and Use Same  Degree of Care and Skill In
Their Exercise,  as Prudent Individual Would Use. (a) The Trustee,  prior to the
occurrence  of an Event of Default  with respect to  Debentures  of a series and
after the curing of all Events of Default  with  respect to  Debentures  of that
series  which may have  occurred,  shall  undertake  to perform  with respect to
Debentures  of such series such duties and only such duties as are  specifically
set forth in this  Indenture,  and no implied  covenants shall be read into this
Indenture  against  the  Trustee.  In case an Event of Default  with  respect to
Debentures  of a series has occurred  (which has not been cured or waived),  the
Trustee  shall  exercise  with respect to  Debentures of that series such of the
rights and powers  vested in it by this  Indenture,  and use the same  degree of
care and skill in their  exercise,  as a prudent man would exercise or use under
the circumstances in the conduct of his own affairs.

         (b) No  provision of this  Indenture  shall be construed to relieve the
Trustee from liability for its own negligent  action,  its own negligent failure
to act, or its own willful misconduct, except that:

               (1) prior to the  occurrence  of an Event of Default with respect
               to  Debentures of a series and after the curing or waiving of all
               such Events of Default with respect to that series which may have
               occurred:

                           (i) the duties and  obligations  of the Trustee shall
                           with  respect  to   Debentures   of  such  series  be
                           determined  solely by the express  provisions of this
                           Indenture,  and the Trustee  shall not be liable with
                           respect to  Debentures  of such series except for the
                           performance  of such  duties and  obligations  as are
                           specifically  set  forth  in this  Indenture,  and no
                           implied  covenants or obligations  shall be read into
                           this Indenture against the Trustee; and

                           (ii) in the  absence  of bad faith on the part of the
                           Trustee,  the Trustee may with respect to  Debentures
                           of such series  conclusively rely, as to the truth of
                           the  statements  and the  correctness of the opinions
                           expressed therein,  upon any certificates or opinions
                           furnished  to  the  Trustee  and  conforming  to  the
                           requirements  of this  Indenture;  but in the case of
                           any  such  certificates  or  opinions  which  by  any
                           provision  hereof  are  specifically  required  to be
                           furnished to the Trustee,  the Trustee shall be under
                           a duty to examine  the same to  determine  whether or
                           not  they  conform  to  the   requirements   of  this
                           Indenture  but need not  confirm or  investigate  the
                           accuracy of mathematical  calculations or other facts
                           stated therein;

                  (2) the Trustee  shall not be liable for any error of judgment
                  made in good faith by a  Responsible  Officer  or  Responsible
                  Officers  of the  Trustee,  unless it shall be proved that the
                  Trustee was negligent in ascertaining the pertinent facts;

                  (3) the Trustee shall not be liable with respect to any action
                  taken or omitted to be taken by it in good faith in accordance
                  with the  direction of the holders of not less than a majority
                  in  principal  amount of the  Debentures  of any series at the
                  time  outstanding  relating  to the time,  method and place of
                  conducting  any  proceeding  for any remedy  available  to the
                  Trustee,  or exercising any trust or power  conferred upon the
                  Trustee under this Indenture with respect to the Debentures of
                  that series; and

                  (4) none of the provisions  contained in this Indenture  shall
                  require  the  Trustee  to  expend  or risk  its own  funds  or
                  otherwise   incur   personal   financial   liability   in  the
                  performance  of any of its duties or in the exercise of any of
                  its  rights  or  powers,  if there is  reasonable  ground  for
                  believing




                                       37

                  that  the   repayment  of  such  funds  or  liability  is  not
                  reasonably  assured to it under the terms of this Indenture or
                  adequate indemnity against such risk is not reasonably assured
                  to it.

                  (5)  Whether  or not  therein  expressly  so  provided,  every
                  provision  of  this  Indenture  relating  to  the  conduct  or
                  affecting  the  liability  of or affording  protection  to the
                  Trustee shall be subject to the provisions of this Article 7.

         SECTION  7.02.  Subject  to  Provisions  of  Section  7.01.  Except  as
otherwise provided in Section 7.01:

                           (a) The  Trustee may rely and shall be  protected  in
                  acting  or  refraining   from  acting  upon  any   resolution,
                  certificate,  statement,  instrument, opinion, report, notice,
                  request,  consent,  order,  approval,  bond, security or other
                  paper or  document  believed  by it to the genuine and to have
                  been signed or presented by the proper party or parties;

                           (b) Any  request,  direction,  order or demand of the
                  Company mentioned herein shall be sufficiently  evidenced by a
                  Board  Resolution or an  instrument  signed in the name of the
                  Company  by the  President  or any Vice  President  and by the
                  Secretary  or an Assistant  Secretary  or the  Treasurer or an
                  Assistant  Treasurer (unless other evidence in respect thereof
                  is specifically prescribed herein);

                           (c) The  Trustee  may  consult  with  counsel  of its
                  selection  and  the  written  advice  of such  counsel  or any
                  Opinion of Counsel  shall be full and  complete  authorization
                  and  protection  in respect of any action taken or suffered or
                  omitted hereunder in good faith and in reliance thereon;

                           (d) The  Trustee  shall  be under  no  obligation  to
                  exercise  any of the  rights  or  powers  vested in it by this
                  Indenture  at the  request,  order or  direction of any of the
                  Debentureholders,   pursuant   to  the   provisions   of  this
                  Indenture,  unless such Debentureholders shall have offered to
                  the  Trustee  reasonable  security  or  indemnity  against the
                  costs,  expenses and liabilities which may be incurred therein
                  or thereby;  nothing herein contained shall, however,  relieve
                  the Trustee of the obligation, upon the occurrence of an Event
                  of Default with respect to a series of the  Debentures  (which
                  has not been  cured or  waived) to  exercise  with  respect to
                  Debentures of that series such of the rights and powers vested
                  in it by this  Indenture,  and to use the same  degree of care
                  and skill in their  exercise,  as a prudent man would exercise
                  or use  under  the  circumstances  in the  conduct  of his own
                  affairs;

                           (e) The  Trustee  shall not be liable  for any action
                  taken or omitted to be taken by it in good faith and  believed
                  by it to be authorized  or within the  discretion or rights or
                  powers conferred upon it by this Indenture;

                           (f) The  Trustee  shall  not be  bound  to  make  any
                  investigation   into  the  facts  or  matters  stated  in  any
                  resolution,   certificate,   statement,  instrument,  opinion,
                  report,  notice,  request,  consent,  order,  approval,  bond,
                  security,  or other papers or documents,  unless  requested in
                  writing so to do by the holders of not less than a majority in
                  principal   amount  of  the  outstanding   Debentures  of  the
                  particular series affected thereby  (determined as provided in
                  Section 8.04); provided, however, that if the payment within a
                  reasonable  time to the  Trustee  of the  costs,  expenses  or
                  liabilities  likely to be incurred by it in the making of such
                  investigation   is,  in  the  opinion  of  the  Trustee,   not
                  reasonably  assured to the Trustee by the security afforded to
                  it by the terms of this  Indenture,  the  Trustee  may require
                  reasonable   indemnity   against   such  costs,   expenses  or
                  liabilities  as a condition to so  proceeding.  The reasonable
                  expense of every such examination shall be paid by the Company
                  or, if paid by the  Trustee,  shall be  repaid by the  Company
                  upon demand; and

                           (g) The  Trustee  may  execute  any of the  trusts or
                  powers  hereunder  or  perform  any  duties  hereunder  either
                  directly or by or through  agents or attorneys and the Trustee
                  shall not be  responsible  for any misconduct or negligence on
                  the part of any agent or attorney  appointed  with due care by
                  it hereunder.

         SECTION  7.03.  Trustee  Not Liable for  Recitals  In  Indenture  Or In
Debentures.  (a) The recitals contained herein and in the Debentures (other than
the  Certificate  of  Authentication  on the  Debentures)  shall be taken as the
statements of the Company,  and the Trustee  assumes no  responsibility  for the
correctness of the same.

         (b)  The  Trustee  makes  no  representations  as to  the  validity  or
sufficiency of this Indenture or of the Debentures.

         (c) The Trustee shall not be accountable  for the use or application by
the Company of any of the Debentures or of the proceeds of such  Debentures,  or
for the use or  application of any moneys paid over by the Trustee in accordance
with any provision of this Indenture or established pursuant to Section 2.01, or
for the use or application of any moneys received by any paying agent other than
the Trustee.

         SECTION  7.04.  Trustee,  Paying Agent or Debenture  Registrar  May Own
Debentures.  The  Trustee or any paying  agent or  Debenture  Registrar,  in its
individual or




                                       39
<PAGE>

any other capacity,  may become the owner or pledgee of Debentures with the same
rights  it  would  have  if it were  not  Trustee,  paying  agent  or  Debenture
Registrar.

         SECTION  7.05.  Moneys  Received by Trustee to Be Held In Trust Without
Interest. Subject to the provisions of Section 11.04, all moneys received by the
Trustee shall,  until used or applied as herein  provided,  be held in trust for
the purposes for which they were received, but need not be segregated from other
funds  except to the  extent  required  by law.  The  Trustee  shall be under no
liability for interest on any moneys received by it hereunder  except such as it
may agree with the Company to pay thereon.

         SECTION  7.06.  Trustee  Entitled to  Compensation,  Reimbursement  and
Indemnity.  (a) The Company covenants and agrees to pay to the Trustee from time
to time, and the Trustee shall be entitled to, such  reasonable  compensation as
the  Company  and the  Trustee  shall from time to time agree in writing  (which
shall not be limited by any provision of law in regard to the  compensation of a
trustee of an express trust) for all services rendered by it in the execution of
the trusts  hereby  created and in the  exercise and  performance  of any of the
powers  and  duties  hereunder  of the  Trustee,  and the  Company  will  pay or
reimburse   the  Trustee   upon  its  request  for  all   reasonable   expenses,
disbursements  and advances  incurred or made by the Trustee in accordance  with
any of the provisions of this Indenture  (including the reasonable  compensation
and the  expenses  and  disbursements  of its  counsel  and of all  persons  not
regularly in its employ) except any such expense, disbursement or advance as may
arise from its negligence or bad faith.  The Company also covenants to indemnify
the Trustee (and its officers, agents, directors and employees) for, and to hold
it harmless against,  any loss, liability or expense including taxes (other than
taxes  based  upon,  measured  by or  determined  by the income of the  Trustee)
incurred without  negligence or bad faith on the part of the Trustee and arising
out of or in connection  with the  acceptance or  administration  of this trust,
including  the costs and  expenses  of  defending  itself  against  any claim of
liability in the premises.

         (b) The obligations of the Company under this Section to compensate and
indemnify  the  Trustee  and to pay  or  reimburse  the  Trustee  for  expenses,
disbursements and advances shall constitute additional  indebtedness  hereunder.
Such  additional  indebtedness  shall be  secured by a lien prior to that of the
Debentures upon all property and funds held or collected by the Trustee as such,
except  funds  held in  trust  for the  benefit  of the  holders  of  particular
Debentures.

         SECTION 7.07.  Right of Trustee to Rely on  Certificate  of Officers of
Company Where No Other  Evidence  Specifically  Prescribed.  Except as otherwise
provided in Section 7.01,  whenever in the  administration  of the provisions of
this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or  established  prior to taking or  suffering  or  omitting  to take any
action  hereunder,  such matter  (unless  other  evidence in respect  thereof be
herein  specifically  prescribed) may, in the absence of negligence or bad faith
on the part of the Trustee,  be deemed to be conclusively proved




                                       40
<PAGE>

and  established by an Officers'  Certificate  delivered to the Trustee and such
certificate,  in the  absence  of  negligence  or bad  faith  on the part of the
Trustee,  shall be full warrant to the Trustee for any action taken, suffered or
omitted to be taken by it under the  provisions of this Indenture upon the faith
thereof.

         SECTION  7.08.  Trustee  Acquiring  Conflicting  Interest to  Eliminate
Conflict  or Resign.  (a) If the Trustee  has or shall  acquire any  conflicting
interest,  as defined in this  Section,  with respect to the  Debentures  of any
series and if the  Default to which such  conflicting  interest  relates has not
been  cured,  duly  waived  or  otherwise  eliminated,   within  90  days  after
ascertaining  that it has such conflicting  interest,  it shall either eliminate
such conflicting  interest,  except as otherwise provided herein, or resign with
respect  to the  Debentures  of that  series in the  manner  and with the effect
specified in Section  7.10 and the Company  shall  promptly  appoint a successor
Trustee in the manner provided herein.

         (b) In the  event  that  the  Trustee  shall  fail to  comply  with the
provisions of subsection (a) of this Section,  with respect to the Debentures of
any series the  Trustee  shall,  within  ten days after the  expiration  of such
90-day  period,  transmit  notice of such failure by mail,  first class  postage
prepaid,  to the  Debentureholders  of that series as their names and  addresses
appear upon the registration books.

         (c) For the  purposes of this  Section  the Trustee  shall be deemed to
have a conflicting  interest  with respect to the  Debentures of any series if a
Default has occurred and is continuing and:

                  (1) the Trustee is trustee under this  Indenture  with respect
                  to the  outstanding  Debentures  of any series other than that
                  series,  or is trustee under another indenture under which any
                  other securities, or certificates of interest or participation
                  in any  other  securities,  of the  Company  are  outstanding,
                  unless such other  indenture is a collateral  trust  indenture
                  under which the only collateral  consists of Debentures issued
                  under this  Indenture;  provided  that there shall be excluded
                  from the  operation of this  paragraph  the  Debentures of any
                  series  other  than that  series  and any other  indenture  or
                  indentures  under which other  securities,  or certificates of
                  interest or participation in other securities,  of the Company
                  are outstanding if (i) this Indenture and such other indenture
                  or indentures and all series of securities issuable thereunder
                  are wholly unsecured and rank equally and such other indenture
                  or indentures (and such series) are hereafter  qualified under
                  the Trust  Indenture  Act,  unless the  Commission  shall have
                  found and  declared  by order  pursuant to  subsection  (b) of
                  Section  305 or  subsection  (c) of  Section  307 of the Trust
                  Indenture  Act,  that   differences   exist  between  (A)  the
                  provisions  of this  Indenture  with respect to  Debentures of
                  that series and with respect to one or more other series or

                  (B) the  provisions of this  Indenture  and the  provisions of
                  such other indenture or indentures (or such series), which are
                  so likely to involve a material  conflict  of  interest  as to
                  make it necessary in the public interest or for the protection
                  of  investors  to  disqualify  the Trustee from acting as such
                  under this  Indenture  with respect to the  Debentures of that
                  series  and such  other  series  or such  other  indenture  or
                  indentures,  or (ii) the  Company  shall  have  sustained  the
                  burden of proving,  on application to the Commission and after
                  opportunity for hearing  thereon,  that the trusteeship  under
                  this  Indenture  with respect to Debentures of that series and
                  such other series or such other indenture or indentures is not
                  so likely to involve a material  conflict  of  interest  as to
                  make it necessary in the public interest or for the protection
                  of  investors  to  disqualify  the Trustee from acting as such
                  under this Indenture with respect to Debentures of that series
                  and such other series or under such other indentures;

                  (2) the Trustee or any of its directors or executive  officers
                  is an underwriter for the Company;

                  (3) the Trustee directly or indirectly controls or is directly
                  or  indirectly  controlled  by or is under  direct or indirect
                  common control with or an underwriter for the Company;

                  (4) the Trustee or any of its directors or executive  officers
                  is  a  director,  officer,  partner,  employee,  appointee  or
                  representative  of the Company,  or of an  underwriter  (other
                  than the Trustee  itself)  for the  Company  who is  currently
                  engaged in the business of  underwriting,  except that (A) one
                  individual  may be a director  and/or an executive  officer of
                  the Trustee and a director and/or an executive  officer of the
                  Company,  but may not be at the same time an executive officer
                  of both the Trustee and the Company; (B) if and so long as the
                  number  of  directors  of the  Trustee  in office is more than
                  nine,  one additional  individual may be a director  and/or an
                  executive  officer  of  the  Trustee  and a  director  of  the
                  Company;  and (C) the Trustee may be designated by the Company
                  or by an underwriter for the Company to act in the capacity of
                  transfer agent,  registrar,  custodian,  paying agent,  fiscal
                  agent,  escrow agent,  or depository,  or in any other similar
                  capacity,  or,  subject to the  provisions of paragraph (1) of
                  this  subsection  (c),  to act as  trustee  whether  under  an
                  indenture or otherwise;

                  (5) 10% or more of the  voting  securities  of the  Trustee is
                  beneficially  owned either by the Company or by any  director,
                  partner,  or executive officer thereof, or 20% or more of such

                  collateral  security for an obligation which is in default (as
                  hereinafter in this subsection (c) defined), (A) 5% or more of
                  the voting  securities,  or 10% or more of any other  class of
                  security,  of the Company, not including the Debentures issued
                  under this  Indenture  and  securities  issued under any other
                  indenture under which the Trustee is also trustee,  or (B) 10%
                  or more of any class of  security  of an  underwriter  for the
                  Company;

                  (7) the  Trustee  is the  beneficial  owner  of,  or  holds as
                  collateral  security for an obligation which is in default (as
                  hereinafter in this subsection (c) defined), 5% or more of the
                  voting  securities  of any person who, to the knowledge of the
                  Trustee,  owns 10% or more of the  voting  securities  of,  or
                  controls directly or indirectly or is under direct or indirect
                  common control with, the Company;

                  (8) the  Trustee  is the  beneficial  owner  of,  or  holds as
                  collateral  security for an obligation which is in default (as
                  hereinafter in this  subsection  (c) defined),  10% or more of
                  any class of security of any person who, to the  knowledge  of
                  the Trustee,  owns 50% or more of the voting securities of the
                  Company;

                  (9)  the  Trustee  owns,  on the  date  of  Default  upon  the
                  Debentures  of any series or any  anniversary  of such Default
                  while  such  Default  upon the  Debentures  issued  under this
                  Indenture  remains  outstanding,  in the capacity of executor,
                  administrator,  testamentary or inter vivos trustee, guardian,
                  committee or conservator, or in any other similar capacity, an
                  aggregate of 25% or more of the voting  securities,  or of any
                  class of security,  of any person, the beneficial ownership of
                  a  specified  percentage  of which  would have  constituted  a
                  conflict of interest under  paragraph (6), (7), or (8) of this
                  subsection (c). As to any such securities of which the Trustee
                  acquired ownership through becoming executor, administrator or
                  testamentary  trustee of an estate which  includes  them,  the
                  provisions of the preceding  sentence  shall not apply,  for a
                  period of two years from the date of such acquisition,  to the
                  extent that such  securities  in such estate do not exceed 25%
                  of  such  voting  securities  or  25%  of any  such  class  of
                  security.  Promptly  after the dates of any such  Default upon
                  the  Debentures  issued under this  Indenture  and annually in
                  each  succeeding  year that the  Debentures  issued under this
                  Indenture remain in Default, the Trustee shall make a check of
                  its holding of such  securities in any of the  above-






                                       43
<PAGE>


                  mentioned capacities as of such dates. If the Company fails to
                  make payment in full of principal of or interest on any of the
                  Debentures  when and as the same becomes due and payable,  and
                  such failure  continues  for 30 days  thereafter,  the Trustee
                  shall make a prompt check of its holding of such securities in
                  any of the  above-mentioned  capacities  as of the date of the
                  expiration  of  such  30-day  period,  and  after  such  date,
                  notwithstanding  the foregoing  provisions  of this  paragraph
                  (9), all such securities so held by the Trustee,  with sole or
                  joint control over such  securities  vested in it, shall,  but
                  only so long as such failure shall continue,  be considered as
                  though  beneficially  owned by the Trustee for the purposes of
                  paragraphs (6), (7) and (8) of this subsection (c); or

                  (10) except  under the  circumstances  described  in paragraph
                  (1), (3),  (4), (5) or (6) of  subsection  (b) of Section 7.13
                  the  Trustee  shall  be or  shall  become  a  creditor  of the
                  Company.

         For purposes of paragraph  (1) of this  subsection  (c), and of Section
6.06, the term "series of securities" or "securities"  means a series,  class or
group of securities  issuable under an indenture pursuant to whose terms holders
of one such series may vote to direct the indenture  trustee,  or otherwise take
action  pursuant to a vote of such holders,  separately  from holders of another
such  series;  provided,  that,  "series of  securities"  or "series"  shall not
include any series of securities  issuable under an indenture if all such series
rank equally and are wholly secured.

         The  specification of percentages in paragraphs (5) to (9),  inclusive,
of this  subsection (c) shall not be construed as indicating  that the ownership
of  such  percentages  of  securities  of a  person  is or is not  necessary  or
sufficient  to  constitute  direct  or  indirect  control  for the  purposes  of
paragraph (3) or (7) of this subsection (c).

         For the purposes of paragraphs (6), (7), (8) and (9) of this subsection
(c) only,  (A) the terms  "security"  and  "securities"  shall include only such
securities as are generally known as corporate securities, but shall not include
any note or other evidence of  indebtedness  issued to evidence an obligation to
repay moneys lent to a person by one or more banks,  trust  companies or banking
firms,  or any  certificate  of  interest or  participation  in any such note or
evidence of indebtedness;  (B) an obligation shall be deemed to be in "default",
when a default in payment of principal  shall have continued for 30 days or more
and shall not have been cured; and (C) the Trustee shall not be deemed to be the
owner or holder of (i) any security  which it holds as  collateral  security (as
trustee or otherwise) for any  obligation  which is not in default as defined in
clause (B) above,  or (ii) any security  which it holds as  collateral  security
under  this  Indenture,  irrespective  of any  Default  hereunder,  or (iii) any
security which it holds as agent for collection,  or as custodian,  escrow agent
or depositary, or in any similar representative capacity.

                  thereof to cast such  specified  percentage  of the  aggregate

                  person  means  such  percentage  of the  aggregate  amount  of

                                       46

                           the  issuer  thereof,  provided,  however,  that  any
                           voting  securities  of  an  issuer  shall  be  deemed
                           outstanding  if any  person  other than the issuer is
                           entitled to exercise the voting rights thereof.

                  (5) A  security  shall be  deemed  to be of the same  class as
                  another security if both securities  confer upon the holder or
                  holders thereof  substantially the same rights and privileges;
                  provided,  however,  that, in the case of secured evidences of
                  indebtedness,   all  of  which  are  issued   under  a  single
                  indenture, differences in the interest rates or maturity dates
                  of various  series  thereof shall not be deemed  sufficient to
                  constitute  such  series  different  classes;   and  provided,
                  further,   that,  in  the  case  of  unsecured   evidences  of
                  indebtedness,  differences  in the interest  rates or maturity
                  dates  thereof  shall not be deemed  sufficient  to constitute
                  them securities of different classes,  whether or not they are
                  issued under a single indenture.

         (f) Except in the case of a default in the payment of the  principal of
(or premium,  if any) or interest on any Debentures issued under this Indenture,
or in the  payment of any sinking or  analogous  fund  installment,  the Trustee
shall not be required to resign as provided by this Section 7.08 if such Trustee
shall have sustained the burden of proving, on application to the Commission and
after opportunity for hearing thereon,  that (i) the default under the Indenture
may be cured or waived  during a  reasonable  period  and  under the  procedures
described in such  application  and (ii) a stay of the Trustee's  duty to resign
will not be inconsistent with the interests of  Debentureholders.  The filing of
such an  application  shall  automatically  stay the  performance of the duty to
resign until the Commission orders otherwise.

         Any  resignation  of the Trustee shall become  effective  only upon the
appointment of a successor  trustee and such  successor's  acceptance of such an
appointment.

         SECTION 7.09.  Requirements for Eligibility of Trustee.  There shall at
all times be a Trustee with respect to the  Debentures  issued  hereunder  which
shall at all times be a corporation  organized and doing business under the laws
of the  United  States of America  or any State or  Territory  thereof or of the
District of  Columbia,  or a  corporation  or other  person  permitted to act as
trustee by the  Commission,  authorized  under such laws to  exercise  corporate
trust  powers,  having a  combined  capital  and  surplus of at least 50 million
dollars,   and  subject  to  supervision  or  examination  by  Federal,   State,
Territorial,  or District of Columbia authority.  If such corporation  publishes
reports of condition at least annually,  pursuant to law or to the  requirements
of the aforesaid  supervising or examining  authority,  then for the purposes of
this  Section,  the combined  capital and surplus of such  corporation  shall be
deemed to be its  combined  capital  and surplus as set forth in its most recent
report of  condition  so  published.  The  Company  may not,  nor may any person
directly or indirectly controlling,  controlled by, or under common control with
the





                                       47
<PAGE>

Company,  serve as Trustee.  In case at any time the  Trustee  shall cease to be
eligible in accordance  with the  provisions of this Section,  the Trustee shall
resign immediately in the manner and with the effect specified in Section 7.10.

         SECTION 7.10. Resignation of Trustee and Appointment of Successor.  (a)
The Trustee or any successor  hereafter  appointed,  may at any time resign with
respect to the Debentures of one or more series by giving written notice thereof
to the Company and by  transmitting  notice of resignation by mail,  first class
postage  prepaid,  to the  Debentureholders  of such series,  as their names and
addresses  appear upon the Debenture  Register.  Upon  receiving  such notice of
resignation, the Company shall promptly appoint a successor trustee with respect
to Debentures of such series by written  instrument,  in duplicate,  executed by
order of the Board of Directors, one copy of which instrument shall be delivered
to the resigning Trustee and one copy to the successor trustee.  If no successor
trustee  shall have been so appointed and have  accepted  appointment  within 30
days after the mailing of such notice of resignation,  the resigning Trustee may
petition any court of competent  jurisdiction for the appointment of a successor
trustee with respect to Debentures  of such series,  or any  Debentureholder  of
that series who has been a bona fide holder of a Debenture or Debentures  for at
least six months may,  subject to the  provisions  of Section 6.08, on behalf of
himself  and all  others  similarly  situated,  petition  any such court for the
appointment of a successor trustee.  Such court may thereupon after such notice,
if any, as it may deem proper and prescribe, appoint a successor trustee.

         (b) In case at any time any of the following shall occur:

                  (1) the Trustee  shall fail to comply with the  provisions  of
                  subsection (a) of Section 7.08 after written request  therefor
                  by the Company or by any  Debentureholder  who has been a bona
                  fide  holder of a  Debenture  or  Debentures  for at least six
                  months; or

                  (2) the Trustee shall cease to be eligible in accordance  with
                  the  provisions of Section 7.09 and shall fail to resign after
                  written  request  therefor  by  the  Company  or by  any  such
                  Debentureholder; or

                  (3) the Trustee shall become incapable of acting,  or shall be
                  adjudged  bankrupt or insolvent,  or a receiver of the Trustee
                  or of its property  shall be appointed,  or any public officer
                  shall take charge or control of the Trustee or of its property
                  or affairs for the purpose of rehabilitation,  conservation or
                  liquidation,

then,  in any such case,  the Company may remove the Trustee with respect to all
Debentures and appoint a successor trustee by written instrument,  in duplicate,
executed by order of the Board of Directors,  one copy of which instrument shall
be delivered to the Trustee so removed and one copy to the successor trustee. If
no successor trustee shall




                                       48
<PAGE>

have been so appointed  and have accepted  appointment  within 30 days after the
mailing of such notice of removal, the Trustee so removed may petition any court
of  competent  jurisdiction  for the  appointment  of a successor  trustee  with
respect to Debentures of such series, or any  Debentureholder of that series who
has been a bona fide holder of a Debenture or Debentures for at least six months
may,  subject to the  provisions  of Section  6.08, on behalf of himself and all
others  similarly  situated,  petition  any such  court for the  removal  of the
Trustee and the  appointment  of a successor  trustee.  Such court may thereupon
after such  notice,  if any,  as it may deem  proper and  prescribe,  remove the
Trustee and appoint a successor trustee.

         (c) The  holders of a majority  in  aggregate  principal  amount of the
Debentures  of any  series at the time  outstanding  may at any time  remove the
Trustee with respect to such series and appoint a successor trustee.

         (d) Any  resignation  or removal of the  Trustee and  appointment  of a
successor  trustee with respect to the Debentures of a series pursuant to any of
the  provisions  of this  Section  shall become  effective  upon  acceptance  of
appointment by the successor trustee as provided in Section 7.11.

         (e) Any  successor  trustee  appointed  pursuant to this Section may be
appointed  with respect to the  Debentures  of one or more series or all of such
series,  and at any time there  shall be only one  Trustee  with  respect to the
Debentures of any particular series.

         SECTION 7.11.  Acceptance  by Successor to Trustee.  (a) In case of the
appointment  hereunder of a successor  trustee  with respect to all  Debentures,
every such successor trustee so appointed shall execute, acknowledge and deliver
to  the  Company  and to the  retiring  Trustee  an  instrument  accepting  such
appointment,  and thereupon the  resignation or removal of the retiring  Trustee
shall become effective and such successor trustee, without any further act, deed
or  conveyance,  shall  become  vested with all the rights,  powers,  trusts and
duties of the  retiring  Trustee;  but,  on the  request  of the  Company or the
successor  trustee,  such retiring  Trustee shall,  upon payment of its charges,
execute and deliver an instrument transferring to such successor trustee all the
rights,  powers,  and trusts of the  retiring  Trustee  and shall  duly  assign,
transfer  and deliver to such  successor  trustee all property and money held by
such retiring Trustee hereunder.

         (b) In case of the  appointment  hereunder of a successor  trustee with
respect to the Debentures of one or more (but not all) series, the Company,  the
retiring  Trustee and each  successor  trustee with respect to the Debentures of
one or more series shall  execute and deliver an indenture  supplemental  hereto
wherein each successor trustee shall accept such appointment and which shall (1)
contain  such  provisions  as shall be  necessary  or  desirable to transfer and
confirm to, and to vest in,  each  successor  trustee  all the  rights,  powers,
trusts and duties of the retiring Trustee with respect to the Debentures of that
or those series to which the appointment of such successor trustee relates,  (2)
contain such





                                       49
<PAGE>


provisions  as shall be deemed  necessary  or  desirable to confirm that all the
rights,  powers,  trusts and duties of the retiring  Trustee with respect to the
Debentures  of that or those  series as to which  the  retiring  Trustee  is not
retiring shall continue to be vested in the retiring Trustee,  and (3) add to or
change any of the  provisions of this Indenture as shall be necessary to provide
for or facilitate the  administration  of the trusts  hereunder by more than one
Trustee,  it  being  understood  that  nothing  herein  or in such  supplemental
indenture  shall  constitute such Trustees  co-trustees of the same trust,  that
each such Trustee shall be trustee of a trust or trusts  hereunder  separate and
apart from any trust or trusts hereunder  administered by any other such Trustee
and that no Trustee  shall be  responsible  for any act or failure to act on the
part of any other Trustee hereunder; and upon the execution and delivery of such
supplemental  indenture the resignation or removal of the retiring Trustee shall
become  effective to the extent provided  therein,  such retiring  Trustee shall
with respect to the Debentures of that or those series to which the  appointment
of such  successor  trustee  relates  have  no  further  responsibility  for the
exercise  of  rights  and  powers  or for  the  performance  of the  duties  and
obligations vested in the Trustee under this Indenture,  and each such successor
trustee,  without any further act, deed or conveyance,  shall become vested with
all the rights,  powers,  trusts and duties of the retiring Trustee with respect
to the  Debentures  of that or those  series  to which the  appointment  of such
successor  trustee  relates;  but,  on request of the  Company or any  successor
Trustee,  such retiring Trustee shall duly assign,  transfer and deliver to such
successor trustee,  to the extent  contemplated by such supplemental  indenture,
the property and money held by such retiring  Trustee  hereunder with respect to
the  Debentures  of that or  those  series  to  which  the  appointment  of such
successor trustee relates.

         (c) Upon  request of any such  successor  trustee,  the  Company  shall
execute  any and all  instruments  for more fully and  certainly  vesting in and
confirming to such successor trustee all such rights,  power and trusts referred
to in paragraph (a) or (b) of this Section, as the case may be.

         (d) No successor  trustee  shall accept its  appointment  unless at the
time of such acceptance  such successor  trustee shall be qualified and eligible
under this Article.

         (e) Upon  acceptance of appointment by a successor  trustee as provided
in this Section,  the Company shall  transmit  notice of the  succession of such
trustee hereunder by mail, first class postage prepaid, to the Debentureholders,
as their names and addresses appear upon the Debenture Register.  If the Company
fails to transmit such notice within ten days after acceptance of appointment by
the  successor  trustee,  the  successor  trustee  shall cause such notice to be
transmitted at the expense of the Company.

         SECTION  7.12.  Successor  to  Trustee  by  Merger,   Consolidation  or
Succession to Business.  Any corporation into which the Trustee may be merged or
converted or with which it may be  consolidated,  or any  corporation  resulting
from any merger, conversion



                                       50
<PAGE>


or  consolidation  to which the  Trustee  shall be a party,  or any  corporation
succeeding to substantially  all of the corporate trust business of the Trustee,
shall be the successor of the Trustee hereunder, provided such corporation shall
be  qualified  under the  provisions  of  Section  7.08 and  eligible  under the
provisions of Section 7.09,  without the execution or filing of any paper or any
further act on the part of any of the  parties  hereto,  anything  herein to the
contrary notwithstanding.  In case any Debentures shall have been authenticated,
but not  made  available  for  delivery,  by the  Trustee  then in  office,  any
successor by merger,  conversion or consolidation to such authenticating Trustee
may adopt such  authentication and make available for delivery the Debentures so
authenticated  with the same  effect as if such  successor  Trustee  had  itself
authenticated such Debentures.

         SECTION 7.13.  Limitations on Rights of Trustee as a Creditor to Obtain
Payment of Certain Claims Within Four Months Prior to Default or During Default,
or to  Realize on  Property  as such  Creditor  Thereafter.  (a)  Subject to the
provisions of subsection  (b) of this Section,  if the Trustee shall be or shall
become a creditor, directly or indirectly,  secured or unsecured, of the Company
within  three months prior to a default,  as defined in  subsection  (b) of this
Section,  or subsequent to such a default,  then,  unless and until such default
shall be cured,  the Trustee  shall set apart and hold in a special  account for
the benefit of the Trustee  individually,  the holders of the Debentures and the
holders of other  indenture  securities  (as defined in  subsection  (c) of this
Section):

                  (1) an amount  equal to any and all  reductions  in the amount
                  due and owing  upon any claim as such  creditor  in respect of
                  principal or interest,  effected  after the  beginning of such
                  three months'  period and valid as against the Company and its
                  other creditors,  except any such reduction resulting from the
                  receipt or disposition of any property  described in paragraph
                  (2) of this  subsection,  or from the exercise of any right of
                  set-off which the Trustee  could have  exercised if a petition
                  in  bankruptcy  had been filed by or against the Company  upon
                  the date of such default; and

                  (2) all  property  received  by the  Trustee in respect of any
                  claim as such  creditor,  either as security  therefor,  or in
                  satisfaction or composition  thereof, or otherwise,  after the
                  beginning of such three months' period,  or an amount equal to
                  the proceeds of any such  property,  if disposed of,  subject,
                  however,  to the rights,  if any, of the Company and its other
                  creditors in such property or such proceeds.

         Nothing  herein  contained,  however,  shall  affect  the  right of the
Trustee:

                  (A) to retain for its own account (i) payments made on account
                  of any such claim by any person  (other than the  Company) who
                  is liable thereon, and (ii) the proceeds of the bona fide sale
                  of any such claim by the Trustee





                                       51
<PAGE>


                  to a third  person,  and  (iii)  distributions  made in  cash,
                  securities,  or other  property  in  respect  of claims  filed
                  against the Company in bankruptcy or receivership or in a case
                  for reorganization  pursuant to the Federal Bankruptcy Code or
                  applicable State law;

                  (B) to realize, for its own account, upon any property held by
                  it as security  for any such claim,  if such  property  was so
                  held prior to the beginning of such three months' period;

                  (C) to realize, for its own account, but only to the extent of
                  the claim hereinafter mentioned,  upon any property held by it
                  as  security  for any such  claim,  if such claim was  created
                  after the  beginning  of such  three  months'  period and such
                  property was received as security therefor simultaneously with
                  the creation  thereof,  and if the Trustee  shall  sustain the
                  burden  of  proving  that at the  time  such  property  was so
                  received the Trustee had no reasonable cause to believe that a
                  default,  as defined in subsection (c) of this Section,  would
                  occur within three months; or

                  (D) to receive  payment on any claim  referred to in paragraph
                  (B) or  (C),  against  the  release  of any  property  held as
                  security for such claim as provided in such  paragraph  (B) or
                  (C),  as the case may be, to the  extent of the fair  value of
                  such property.

         For the purposes of paragraphs (B), (C) and (D),  property  substituted
after the beginning of such three  months'  period for property held as security
at the time of such  substitution  shall, to the extent of the fair value of the
property released,  have the same status as the property  released,  and, to the
extent  that any claim  referred  to in any of such  paragraphs  is  created  in
renewal of or in  substitution  for or for the purpose of repaying or  refunding
any  pre-existing  claim of the Trustee as such creditor,  such claim shall have
the same status as such pre-existing claim.

         If the Trustee  shall be required  to account,  the funds and  property
held in such  special  account and the  proceeds  thereof  shall be  apportioned
between the Trustee,  the  Debentureholders  and the holders of other  indenture
securities in such manner that the Trustee, the Debentureholders and the holders
of other indenture securities realize, as a result of payments from such special
account  and  payments  of  dividends  on claims  filed  against  the Company in
bankruptcy  or  receivership  or in a case for  reorganization  pursuant  to the




                                       52
<PAGE>


Federal  Bankruptcy  Code or applicable  State law, the same percentage of their
respective claims, figured before crediting to the claim of the Trustee anything
on account of the  receipt by it from the  Company of the funds and  property in
such  special  account  and before  crediting  to the  respective  claims of the
Trustee,  the  Debentureholders  and the holders of other  indenture  securities
dividends on claims filed against the Company in bankruptcy or  receivership  or
in a  case  for  reorganization  pursuant  to the  Federal  Bankruptcy  Code  or
applicable  State law, but after  crediting  thereon  receipts on account of the
indebtedness  represented by their respective claims from all sources other than
from such  dividends  and from the funds and  property  so held in such  special
account.  As used  in this  paragraph,  with  respect  to any  claim,  the  term
"dividends"  shall  include any  distribution  with  respect to such  claim,  in
bankruptcy  or  receivership  or in a case for  reorganization  pursuant  to the
Federal  Bankruptcy Code or applicable State law,  whether such  distribution is
made in cash,  securities,  or other  property,  but shall not  include any such
distribution  with respect to the secured  portion,  if any, of such claim.  The
court in which such  bankruptcy,  receivership or a case for  reorganization  is
pending  shall have  jurisdiction  (i) to  apportion  between the  Trustee,  the
Debentureholders  and the holders of other indenture  securities,  in accordance
with the  provisions  of this  paragraph,  the funds and  property  held in such
special account and the proceeds thereof, or (ii) in lieu of such apportionment,
in  whole  or in  part,  to  give  to  the  provisions  of  this  paragraph  due
consideration in determining the fairness of the distributions to be made to the
Trustee, the Debentureholders and the holders of other indenture securities with
respect to their respective  claims, in which event it shall not be necessary to
liquidate or to appraise the value of any  securities or other  property held in
such special  account or as security  for any such claim,  or to make a specific
allocation of such  distributions as between the secured and unsecured  portions
of such  claims,  or otherwise to apply the  provisions  of this  paragraph as a
mathematical formula.

         Any Trustee who has  resigned or been  removed  after the  beginning of
such three months' period shall be subject to the provisions of this  subsection
(a) as though such  resignation or removal had not occurred.  If any Trustee has
resigned or been removed prior to the beginning of such three months' period, it
shall be subject to the  provisions  of this  subsection  (a) if and only if the
following conditions exist:

                  (i) the receipt of property or  reduction of claim which would
                  have given rise to the obligation to account,  if such Trustee
                  had continued as trustee, occurred after the beginning of such
                  three months' period; and

                  (ii) such receipt of property or  reduction of claim  occurred
                  within three months after such resignation or removal.

         (b) There shall be excluded  from the  operation of  subsection  (a) of
this Section a creditor relationship arising from:

                  (1) the ownership or  acquisition  of securities  issued under
                  any indenture, or any security or securities having a maturity
                  of one year or more at the time of acquisition by the Trustee;

                  (2) advances  authorized by a receivership or bankruptcy court
                  of  competent  jurisdiction,  or by  this  Indenture,  for the
                  purpose of preserving




                                       53
<PAGE>


                  any  property  other  than  cash  which  shall  at any time be
                  subject  to  the  lien,  if  any,  of  this  Indenture  or  of
                  discharging  tax liens or other  prior  liens or  encumbrances
                  thereon,  if notice of such  advance and of the  circumstances
                  surrounding    the   making    thereof   is   given   to   the
                  Debentureholders  at the time and in the  manner  provided  in
                  this Indenture;

                  (3)  disbursements  made in the ordinary course of business in
                  the capacity of trustee  under an indenture,  transfer  agent,
                  registrar, custodian, paying agent, subscription agent, fiscal
                  agent or depositary, or other similar capacity;

                  (4) an indebtedness  created as a result of services  rendered
                  or premises rented; or an indebtedness  created as a result of
                  goods or securities  sold in a cash  transaction as defined in
                  subsection (c) of this Section;

                  (5) the ownership of stock or of other securities of a Company
                  organized under the provisions of Section 25(a) of the Federal
                  Reserve  Act, as amended,  which is directly or  indirectly  a
                  creditor of the Company; or

                  (6) the acquisition,  ownership,  acceptance or negotiation of
                  any drafts, bills of exchange, acceptance or obligations which
                  fall within the  classification of  self-liquidating  paper as
                  defined in subsection (c) of this Section.

         (c) As used in this Section:

                  (1) The term "default"  shall mean any failure to make payment
                  in full of the  principal of (or premium,  if any) or interest
                  upon  any  of  the  Debenture  or  upon  the  other  indenture
                  securities when and as such principal (or premium,  if any) or
                  interest becomes due and payable.

                  (2) Th e  term  "other   indenture   securities"   shall  mean
                  securities upon which the Company is an obligor (as defined in
                  the Trust Indenture Act) outstanding under any other indenture
                  (A)  under  which  the  Trustee  is also  trustee,  (B)  which
                  contains provisions substantially similar to the provisions of
                  subsection (a) of this Section,  and (C) under which a default
                  exists  at the  time of the  apportionment  of the  funds  and
                  property held in said special account.

                            CONCERNING THE DEBENTURES

         SECTION 8.01. Evidence of Action by Debentureholders.  Whenever in this
Indenture it is provided that the holders of a majority or specified  percentage
in aggregate  principal amount of the Debentures of a particular series may take
any action  (including  the making of any demand or  request,  the giving of any
notice,  consent or waiver or the taking of any other  action)  the fact that at
the time of taking any such  action the holders of such  majority  or  specified
percentage of that series have joined therein may be evidenced by any instrument
or any  number of  instruments  of similar  tenor  executed  by such  holders of
Debentures of that series in person or by agent or proxy appointed in writing.

         If the Company  shall solicit from the  Debentureholders  of any series
any request, demand, authorization,  direction, notice, consent, waiver or other
action,   the  Company  may,  at  its  option,  as  evidenced  by  an  Officers'
Certificate,  fix in advance a record date for such series for the determination
of  Debentureholders  entitled  to give  such  request,  demand,  authorization,
direction,  notice,  consent, waiver or other action, but the Company shall have
no  obligation to do so. If such a record date is fixed,  such request,  demand,
authorization,  direction,  notice, consent, waiver or other action may be given
before or after the record date, but only the  Debentureholders of record at the
close of business on the record date shall be deemed to be Debentureholders  for
the purposes of determining whether Debentureholders of the requisite proportion
of outstanding  Debentures of that series have authorized or agreed or consented
to such request, demand,  authorization,  direction,  notice, consent, waiver or
other  action,  and for that purpose the  outstanding  Debentures of that series
shall be computed as of the record date; provided




                                       55
<PAGE>


that no such authorization, agreement or consent by such Debentureholders on the
record date shall be deemed effective unless it shall become effective  pursuant
to the  provisions of this  Indenture not later than six months after the record
date.

         SECTION  8.02.  Proof of  Execution  of  Instruments  and of Holding of
Debentures. Subject to the provisions of Section 7.01, proof of the execution of
any instrument by a Debentureholder  (such proof will not require  notarization)
or his  agent or proxy  and  proof of the  holding  by any  person of any of the
Debentures shall be sufficient if made in the following manner;

                  (a) The fact and date of the  execution  by any such person of
                  any  instrument  may  be  proved  in  any  reasonable   manner
                  acceptable to the Trustee.

                  (b)  The  ownership  of  Debentures  shall  be  proved  by the
                  Debenture  Register of such  Debentures or by a certificate of
                  the Debenture Registrar thereof.

                  (c) The  Trustee  may  require  such  additional  proof of any
                  matter referred to in this Section as it shall deem necessary.

         SECTION 8.03. Who May Be Deemed Owners of Debentures.  Prior to the due
presentment  for  registration  of transfer of any Debenture,  the Company,  the
Trustee,  any paying agent and any  Debenture  Registrar  may deem and treat the
person in whose name such  Debenture  shall be registered  upon the books of the
Company as the absolute owner of such  Debenture  (whether or not such Debenture
shall be overdue and  notwithstanding any notice of ownership or writing thereon
made by anyone other than the Debenture  Registrar) for the purpose of receiving
payment of or on account of the principal of,  premium,  if any, and (subject to
Section 2.03) interest on such Debenture and for all other purposes; and neither
the Company nor the Trustee  nor any paying  agent nor any  Debenture  Registrar
shall be affected by any notice to the contrary.

         SECTION  8.04.   Debentures   Owned  by  a  Company  or  Controlled  or
Controlling  Companies  Disregarded for Certain Purposes. In determining whether
the holders of the  requisite  aggregate  principal  amount of  Debentures  of a
particular series have concurred in any direction,  consent or waiver under this
Indenture, Debentures of that series which are owned by the Company or any other
obligor on the  Debentures of that series or by any Subsidiary of the Company or
of such other obligor on the Debentures of that series shall be disregarded  and
deemed not to be outstanding for the purpose of any such  determination,  except
that for the purpose of  determining  whether the Trustee  shall be protected in
relying on any such direction, consent or waiver, only Debentures of such series
which  the  Trustee  actually  knows  are  so  owned  shall  be so  disregarded.
Debentures  so owned  which have been  pledged in good faith may be  regarded as




                                       56
<PAGE>


outstanding for the purposes of this Section,  if the pledgee shall establish to
the  satisfaction  of the Trustee the pledgee's  right so to act with respect to
such  Debentures  and that the pledgee is not a person  directly  or  indirectly
controlling or controlled by or under direct or indirect common control with the
Company or any such other  obligor.  In case of a dispute as to such right,  any
decision  by the  Trustee  taken  upon  the  advice  of  counsel  shall  be full
protection to the Trustee.

         SECTION  8.05.  Instruments  Executed by  Debentureholders  Bind Future
Holders.  At any time prior to (but not after) the evidencing to the Trustee, as
provided  in Section  8.01,  of the  taking of any action by the  holders of the
majority or  percentage  in aggregate  principal  amount of the  Debentures of a
particular  series  specified in this Indenture in connection  with such action,
any holder of a Debenture  of that series  which is shown by the  evidence to be
included in the  Debentures  the holders of which have  consented to such action
may, by filing  written  notice with the  Trustee,  and upon proof of holding as
provided in Section 8.02,  revoke such action so far as concerns such Debenture.
Except as aforesaid any such action taken by the holder of any  Debenture  shall
be  conclusive  and  binding  upon such  holder and upon all future  holders and
owners of such Debenture,  and of any Debenture issued in exchange therefor,  on
registration of transfer thereof or in place thereof, irrespective of whether or
not any notation in regard thereto is made upon such Debenture. Any action taken
by the holders of the majority or  percentage in aggregate  principal  amount of
the Debentures of a particular  series specified in this Indenture in connection
with such action shall be conclusively binding upon the Company, the Trustee and
the holders of all the Debentures of that series.

                             SUPPLEMENTAL INDENTURES

         SECTION 9.01. Purposes for Which Supplemental  Indenture May Be Entered
Into  Without  Consent of  Debentureholders.  In  addition  to any  supplemental
indenture otherwise authorized by this Indenture,  the Company,  when authorized
by a Board  Resolution,  and the  Trustee  may from time to time and at any time
enter into an indenture or indentures  supplemental  hereto (which shall conform
to the  provisions of the Trust  Indenture  Act as then in effect),  without the
consent of the Debentureholders, for one or more of the following purposes:

                  (a) to evidence the  succession of another  corporation to the
                  Company,  and the  assumption  by any  such  successor  of the
                  covenants  of  the  Company   contained  herein  or  otherwise
                  established with respect to the Debentures; or



                                       57
<PAGE>

                  (b) to  add to the  covenants  of  the  Company  such  further
                  covenants,  restrictions,  conditions  or  provisions  for the
                  protection  of the  holders  of the  Debentures  of all or any
                  series  as the  Board  of  Directors  and  the  Trustee  shall
                  consider to be for the protection of the holders of Debentures
                  of all or any  series,  and to  make  the  occurrence,  or the
                  occurrence  and  continuance,  of a  default  in any  of  such
                  additional covenants, restrictions, conditions or provisions a
                  default or an Event of  Default  with  respect to such  series
                  permitting  the  enforcement  of all  or  any  of the  several
                  remedies  provided  in this  Indenture  as herein  set  forth;
                  provided,  however,  that in  respect  of any such  additional
                  covenant,    restriction,    condition   or   provision   such
                  supplemental  indenture may provide for a particular period of
                  grace  after  default  (which  period may be shorter or longer
                  than  that  allowed  in the  case of  other  defaults)  or may
                  provide for an immediate  enforcement upon such default or may
                  limit the remedies  available to the Trustee upon such default
                  or may  limit  the  right  of the  holders  of a  majority  in
                  aggregate principal amount of the Debentures of such series to
                  waive such default; or

                  (c) to cure any  ambiguity  or to  correct or  supplement  any
                  provision  contained herein or in any  supplemental  indenture
                  which  may  be  defective  or  inconsistent   with  any  other
                  provision  contained herein or in any supplemental  indenture,
                  or to make such  other  provisions  in regard  to  matters  or
                  questions  arising  under  this  Indenture  as  shall  not  be
                  inconsistent  with the  provisions of this Indenture and shall
                  not  adversely  affect  the  interests  of the  holders of the
                  Debentures of any series; or

                  (d) to  change  or  eliminate  any of the  provisions  of this
                  Indenture,  provided that any such change or elimination shall
                  become  effective only when there is no Debenture  outstanding
                  of  any  series   created  prior  to  the  execution  of  such
                  supplemental  indenture  which is  entitled  to the benefit of
                  such provision.

         The  Trustee  is  hereby  authorized  to join with the  Company  in the
execution  of  any  such  supplemental  indenture,   and  to  make  any  further
appropriate agreements and stipulations which may be therein contained,  but the
Trustee  shall not be  obligated to enter into any such  supplemental  indenture
which  affects  the  Trustee's  own  rights,  duties or  immunities  under  this
Indenture or otherwise.

         Any supplemental indenture authorized by the provisions of this Section
may be  executed  by the  Company  and the  Trustee  without  the consent of the
holders of any of the Debentures at the time outstanding, notwithstanding any of
the provisions of Section 9.02.

         SECTION   9.02.    Modification    of   Indenture   with   Consent   of
Debentureholders.  With the consent  (evidenced  as provided in Section 8.01) of
the holders of not less than a majority  in  aggregate  principal  amount of the
Debentures of each series affected by such supplemental  indenture or indentures
at the time  outstanding  (and, in the case of any series of Debentures  held as
trust assets of an AES Trust and with  respect to which a Security  Exchange has
not theretofore  occurred,  such consent of holders of the Preferred  Securities
and the  Common  Securities  of such AES  Trust  as may be  required  under  the
Declaration of Trust of such AES Trust), the Company, when authorized by a Board
Resolution,  and the Trustee may from time to time and at any time enter into an
indenture  or  indentures  supplemental  hereto  (which  shall  conform  to  the
provisions  of the Trust  Indenture  Act as then in effect)  for the  purpose of
adding any  provisions  to or changing in any manner or  eliminating  any of the
provisions of this Indenture or of any supplemental indenture or of modifying in
any manner the rights of the holders of the Debentures of such series under this
Indenture;  provided,  however,  that no such  supplemental  indenture shall (i)
extend  the fixed  maturity  of any  Debentures  of any  series,  or reduce  the
principal  amount  thereof,  or reduce the rate or extend the time of payment of
interest  thereon,  or reduce any premium  payable upon the redemption  thereof,
without the consent of the holder of each  Debenture  so affected or (ii) reduce
the  aforesaid  percentage of  Debentures,  the holders of which are required to
consent to any such supplemental  indenture,  without the consent of the holders
of each  Debenture  (and, in the case of any series of Debentures  held as trust
assets of an AES Trust and with  respect  to which a Security  Exchange  has not
theretofore  occurred,  such consent of the holders of the Preferred  Securities
and the  Common  Securities  of such AES  Trust  as may be  required  under  the
Declaration of Trust of such AES Trust) then outstanding and affected thereby.

         Upon the  request of the  Company,  accompanied  by a Board  Resolution
authorizing  the  execution  of any such  supplemental  indenture,  and upon the
filing with the Trustee of evidence of the consent of Debentureholders  (and, in
the case of any series of  Debentures  held as trust  assets of an AES Trust and
with respect to which a Security  Exchange has not  theretofore  occurred,  such
consent of holders of the Preferred Securities and the Common Securities of such
AES Trust as may be required  under the  Declaration of Trust of such AES Trust)
required  to  consent  thereto as  aforesaid,  the  Trustee  shall join with the
Company in the execution of such supplemental indenture unless such supplemental
indenture  affects the  Trustee's own rights,  duties or  immunities  under this
Indenture  or  otherwise,  in which case the Trustee may in its  discretion  but
shall not be obligated to enter into such supplemental indenture.

         It shall not be necessary  for the consent of the  Debentureholders  of
any series affected thereby under this Section to approve the particular form of
any proposed supplemental indenture,  but it shall be sufficient if such consent
shall approve the substance thereof.






                                       59
<PAGE>

         Promptly  after the  execution  by the  Company  and the Trustee of any
supplemental  indenture pursuant to the provisions of this Section,  the Trustee
shall transmit by mail, first class postage prepaid, a notice,  setting forth in
general   terms  the   substance  of  such   supplemental   indenture,   to  the
Debentureholders  of all series  affected  thereby as their names and  addresses
appear  upon the  Debenture  Register.  Any  failure of the Trustee to mail such
notice, or any defect therein,  shall not, however,  in any way impair or affect
the validity of any such supplemental indenture.

         SECTION 9.03. Effect of Supplemental Indentures.  Upon the execution of
any  supplemental  indenture  pursuant to the  provisions  of this Article or of
Section 10.01,  this  Indenture  shall,  with respect to such series,  be and be
deemed to be modified and amended in  accordance  therewith  and the  respective
rights,  limitations of rights,  obligations,  duties and immunities  under this
Indenture  of the  Trustee,  the Company and the  holders of  Debentures  of the
series affected thereby shall  thereafter be determined,  exercised and enforced
hereunder subject in all respects to such modifications and amendments,  and all
the terms and  conditions  of any such  supplemental  indenture  shall be and be
deemed to be part of the terms and  conditions of this Indenture for any and all
purposes.

         SECTION 9.04.  Debentures May Bear Notation of Changes By  Supplemental
Indentures.  Debentures  of any series,  affected by a  supplemental  indenture,
authenticated and delivered after the execution of such  supplemental  indenture
pursuant  to the  provisions  of this  Article or of Section  10.01,  may bear a
notation  in  form  approved  by the  Company,  provided  such  form  meets  the
requirements  of any  exchange  upon which such series may be listed,  as to any
matter  provided for in such  supplemental  indenture.  If the Company  shall so
determine,  new  Debentures  of that series so  modified  as to conform,  in the
opinion  of the  Board  of  Directors,  to any  modification  of this  Indenture
contained  in any such  supplemental  indenture  may be prepared by the Company,
authenticated  by the Trustee and  delivered in exchange for the  Debentures  of
that series then outstanding.

         SECTION  9.05.  Opinion  of  Counsel.  The  Trustee,   subject  to  the
provisions  of Section  7.01,  may  receive an Opinion of Counsel as  conclusive
evidence that any supplemental  indenture  executed  pursuant to this Article is
authorized  or permitted by, and conforms to, the terms of this Article and that
it is proper for the Trustee under the provisions of this Article to join in the
execution thereof.

Company shall not permit any other Person to consolidate  with or merge into the

                           (a)  either  the  Company  shall  be  the  continuing
                  corporation,  or the  corporation  (if other than the Company)
                  formed by such  consolidation  or into  which the  Company  is
                  merged or to which the  properties  and assets of the  Company
                  substantially  as an entity are transferred or leased shall be

corporation  formed by such consolidation or into which the Company is merged or
to which such transfer or lease is made shall succeed to and be substituted for,
and may exercise every right and power of, the Company under this Indenture with
the same effect as if such successor  corporation  had been named as the Company
herein,  and  thereafter  (except in the case of a lease to another  Person) the
predecessor corporation shall be relieved of all obligations and covenants under
the  Indenture  and the  Debentures  and,  in the  event of such  conveyance  or
transfer, any such predecessor corporation may be dissolved and liquidated.

         SECTION  10.03.  Opinion  of  Counsel.  The  Trustee,  subject  to  the
provisions  of Section  7.01,  may  receive an Opinion of Counsel as  conclusive

other disposition,  and any such assumption,  comply with the provisions of this
Article.

in  Section  2.07)  or (c) (i) all the  Debentures  of  series  not  theretofore

                  arrangements satisfactory to the Trustee), as the case may be,
                  and (B) any  mandatory  sinking fund  payments on the dates on
                  which such payments are due and payable in accordance with the
                  terms of the Indenture and the Debentures of such series;

                  (b) such deposit will not result in a breach or violation  of,

                  (c) the  Company  has  delivered  to the Trustee an Opinion of
                  Counsel  based on the fact that (x) the Company  has  received
                  from,  or there has been  published  by, the Internal  Revenue
                  Service a ruling or (y) since the date hereof,  there has been
                  a change in the  applicable  Federal income tax law, in either
                  case to the effect that,  and such opinion shall confirm that,
                  the  holders  of  the  Debentures  of  such  series  will  not
                  recognize income, gain or loss for Federal income tax purposes
                  as a result of such deposit, defeasance and discharge and will
                  be subject to Federal income tax on the same amount and in the
                  same manner and at the same times, as would have been the case
                  if such deposit, defeasance and discharge had not occurred;

                  (d) the Company  has  delivered  to the  Trustee an  Officer's
                  Certificate  and an Opinion of Counsel,  each stating that all

                  provisions  of  Section  14.02 or  14.03,  would  prevent  the
                  Company from making  payments of the  principal of or interest
                  on the Debentures of such series on the date of such deposit.

         SECTION 11.02. Application of Trustee of Funds Deposited For Payment of
Debentures.  Subject to Section 11.04, all moneys deposited with the Trustee (or
other  trustee)  pursuant to Section 11.01 shall be held in trust and applied by
it to the payment,  either  directly or through any paying agent  (including the
Company  acting as its own  paying  agent),  to the  Holders  of the  particular
Debentures  of such  series for the payment or  redemption  of which such moneys
have been deposited with the Trustee,  of all sums due and to become due thereon
for  principal and  interest;  but such money need not be segregated  from other
funds except to the extent required by law.

         SECTION 11.03. Application by Trustee of Funds Deposited For Payment of
Debentures.  In connection with the satisfaction and discharge of this Indenture

agent under the  provisions  of this  Indenture  with  respect to such series of
Debentures  shall,  upon demand of the  Company,  be repaid to it or paid to the
Trustee  and  thereupon  such paying  agent  shall be released  from all further
liability with respect to such moneys.

         SECTION  11.04.  Repayment of Moneys Held by Paying  Agent.  Any moneys
deposited with or paid to the Trustee or any paying agent for the payment of the
principal  of or  interest  on any  Security  of any series and not  applied but
remaining  unclaimed  for two years after the date upon which such  principal or
interest shall have become due and payable,  shall,  upon the written request of
the Company and unless otherwise required by



                                       64
<PAGE>

mandatory  provisions of applicable  escheat or abandoned or unclaimed  property
law,  be repaid to the  Company by the  Trustee  for such  series or such paying
agent,  and the Holder of the Debentures of such series shall,  unless otherwise
required by mandatory provisions of applicable escheat or abandoned or unclaimed
property  laws,  thereafter  look only to the Company for any payment which such
holder may be  entitled  to  collect,  and all  liability  of the Trustee or any
paying  agent with  respect to such  moneys  shall  thereupon  cease;  provided,
however,  that the Trustee or such paying agent,  before being  required to make
any such  repayment  with  respect to moneys  deposited  with it for any payment
series, shall at the expense of the Company, mail by first-class mail to holders
of such  Debentures  at their  addresses as they shall  appear on the  Debenture
Register,  notice,  that such  moneys  remain and that,  after a date  specified
therein,  which shall not be less than thirty days from the date of such mailing
or  publication,  any  unclaimed  balance of such money then  remaining  will be
repaid to the Company.

         SECTION 11.05.  Repayment of Moneys Paid by Trustee.  The Company shall
pay and indemnify the Trustee against any tax, fee or other charge imposed on or
assessed  against the  Governmental  Obligations  deposited  pursuant to Section
11.01 or the principal or interest received in respect of such obligations.

         SECTION 13.10.  Separability of Indenture Provisions.  .In case any one
or more of the  provisions  contained in this  Indenture or in the Debentures of
any series shall for any reason be held to be invalid,  illegal or unenforceable
in any respect, such invalidity, illegality or unenforceability shall not affect
any other provisions of this Indenture or of such Debentures, but this Indenture
and  such  Debentures  shall be  construed  as if such  invalid  or  illegal  or
unenforceable provision had never been contained herein or therein.

         SECTION 13.11.  Assignment by Company to  Subsidiary.  The Company will
have the right at all times to assign  any of its  rights or  obligations  under
this Indenture to a direct or indirect  wholly owned  Subsidiary of the Company;
provided  that,  in the event of any such  assignment,  the Company  will remain
jointly and severally liable for all such obligations. Subject to the foregoing,

Beneficiaries  of the Indenture;  Holders of Preferred  Securities May Institute
Legal  Proceedings  Against the  Company in Certain  Cases.  The Company  hereby
acknowledges  that,  to the extent  specifically  set forth  herein,  prior to a
Security  Exchange  with respect to the  Debentures  of any series held as trust
assets of a AES Trust, the holders of the Preferred Securities of such AES Trust
shall  expressly be third party  beneficiaries  of this  Indenture.  The Company
further  acknowledges  that,  prior  to a  Security  Exchange  with  respect  to
Debentures  of any series held as trust  assets of a AES Trust,  if the Property
Trustee of such AES Trust fails to enforce its rights  under this  Indenture  as
the holder of the Debentures of a series held as trust assets of such AES Trust,
any holder of the Preferred  Securities  of such AES Trust may  institute  legal
proceedings  directly  against the Company to enforce  such  Property  Trustee's
rights under this  Indenture  without first  instituting  any legal  proceedings
against such Property  Trustee or any other person or entity;  provided that, if
an Event of Default has occurred and is continuing  and such event is attributed
to the failure of the Company to pay interest or principal on the  Debentures on
the date such  interest or  principal  is  otherwise  payable (or in the case of
redemption,  on the redemption date),  then a holder of Preferred  Securities of
such AES Trust may directly institute a proceeding for enforcement of payment to
such holder of the principal of or interest on the Debentures having a principal
amount equal to the aggregate  liquidation amount of the Preferred Securities of
such  holder (a "Holder  Direct  Action")  on or after the  respective  due date
specified in the Debentures.  In connection with such Holder Direct Action,  the
rights  of the  holders  of the  Common  Securities  of such AES  Trust  will be
subrogated to the rights of such holder of Preferred Securities to the extent of
any payment made by the Company to such holders of Preferred  Securities in such
Holder Direct Action. Except as provided in the preceding sentences, the holders
of Preferred  Securities of such AES Trust will not be able to exercise directly
any other  remedy  available  to the holders of the  Debentures.  Reference to a
"holder" of Preferred

Securities or Common  Securities herein shall mean a "Holder" of such securities
as defined in the Declaration of Trust.

                           SUBORDINATION OF DEBENTURES

         SECTION  14.01.  Agreement to  Subordinate.  The Company  covenants and
agrees,  and each  Debentureholder  issued  hereunder by his acceptance  thereof
likewise  covenants and agrees,  that all Debentures  shall be issued subject to
the provisions of this Article;  and each person holding any Debenture,  whether
upon original issue or upon transfer, assignment or exchange thereof accepts and
agrees that the  Principal of and interest on all  Debentures  issued  hereunder
shall,  to the extent and in the manner herein set forth,  be  subordinated  and
subject in right to the prior  payment  in full of all  Senior and  Subordinated
Debt.

         SECTION 14.02. Payments to Debentureholders.  No payments on account of
principal of, premium, if any, or interest on the Debentures shall be made if at
the time of such payment or immediately  after giving effect thereto there shall
exist a default in any payment with respect to any Senior and Subordinated Debt,
and such event of default  shall not have been cured or waived or shall not have
ceased to exist.  In  addition,  during the  continuance  of any other  event of
default  (other than a payment  default) with respect to  Designated  Senior and
Subordinated  Debt  pursuant to which the maturity  thereof may be  accelerated,
from and after the date of receipt by the  Trustee  of written  notice  from the
holders of such Designated Senior and Subordinated Debt or from an agent of such
holders,  no payments on account of principal,  premium,  if any, or interest in
respect of the  Debentures  may be made by the  Company  for a period  ("Payment
Blockage  Period")  commencing on the date of delivery of such notice and ending
179 days thereafter  (unless such Payment Blockage Period shall be terminated by
written  notice to the Trustee  from the holders of such  Designated  Senior and
Subordinated Debt or from an agent of such holders, or such event of default has
been cured or waived or has ceased to exist).  Only one Payment  Blockage Period
may be  commenced  with  respect  to the  Debentures  during  any  period of 360
consecutive  days. No event of default  which  existed or was  continuing on the
date of the  commencement  of any Payment  Blockage  Period with  respect to the
Designated  Senior and Subordinated Debt initiating such Payment Blockage Period
shall be or be made the basis for the  commencement  of any  subsequent  Payment
Blockage Period by the holders of such Designated Senior and Subordinated  Debt,
unless such event of default shall have been cured or waived for a period of not
less than 90 consecutive days.

         Upon any payment or  distribution  of assets of the Company of any kind
or character,  whether in cash,  property or  securities,  to creditors upon any

benefit of creditors,  marshalling of assets and  liabilities or any bankruptcy,
insolvency or similar  proceedings of the Company,  all amounts due or to become
due upon all Senior and  Subordinated  Debt shall first be paid in full, in cash
or cash  equivalents,  or payment  thereof  provided for in accordance  with its
terms,  before any payment is made on account of the principal of,  premium,  if
any, or interest on the indebtedness  evidenced by the Debentures,  and upon any
such  liquidation,   dissolution,  winding  up,  receivership,   reorganization,
assignment,  marshalling or proceeding, any payment or distribution of assets of
the Company of any kind or character,  whether in cash,  property or securities,
to which the  Debentureholders  or the  Trustee  under this  Indenture  would be
entitled,  except for the provisions hereof,  shall be paid by the Company or by
any receiver, trustee in bankruptcy,  liquidating trustee, agent or other Person
making  such  payment  or  distribution,  or by the  Debentureholders  or by the
Trustee under this Indenture if received by them or it,  directly to the holders
of Senior and  Subordinated  Debt (pro rata to such  holders on the basis of the
respective  amounts of Senior and  Subordinated  Debt held by such  holders)  or
their  respective  representatives,  or to the  trustee  or  trustees  under any
indenture  pursuant to which any  instruments  evidencing any of such Senior and
Subordinated  Debt may have  been  issued,  as their  respective  interests  may
appear,  to the extent necessary to pay all Senior and Subordinated Debt in full
(including,  without  limitation,  except to the extent,  if any,  prohibited by
mandatory provisions of law,  post-petition  interest, in any such proceedings),
after giving  effect to any  concurrent  payment or  distribution  to or for the
holders of Senior and Subordinated  Debt,  before any payment or distribution is
made to the holders of the  indebtedness  evidenced by the  Debentures or to the
Trustee under this Indenture.

         In the event  that,  notwithstanding  the  foregoing,  any  payment  or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities,  prohibited by the  foregoing,  shall be received by the
Trustee under this Indenture or the holders of the Debentures  before all Senior
and  Subordinated  Debt is paid in full or provision is made for such payment in
accordance with its terms,  such payment or distribution  shall be held in trust
for the  benefit of and shall be paid over or  delivered  to the holders of such
Senior and  Subordinated  Debt or their  respective  representatives,  or to the
trustee  or  trustees  under any  indenture  pursuant  to which any  instruments
evidencing  any of such Senior and  Subordinated  Debt may have been issued,  as
their  respective  interests may appear,  for  application to the payment of all
Senior  and  Subordinated  Debt  remaining  unpaid  until  all such  Senior  and
Subordinated  Debt  shall have been paid in full in  accordance  with its terms,
after giving  effect to any  concurrent  payment or  distribution  to or for the
holders of such Senior and Subordinated Debt.

         For purposes of this Article, the words, "cash, property or securities"
shall not be deemed to include  shares of stock of the Company as reorganized or
readjusted,  or securities of the Company or any other corporation  provided for
by a plan of arrangement,  reorganization or readjustment,  the payment of which
is subordinated (at least to the




                                       70
<PAGE>

extent  provided in this Article with respect to the  Debentures) to the payment
of all  Senior  and  Subordinated  Debt  which  may at the time be  outstanding;
provided,  that (i) the  Senior  and  Subordinated  Debt is  assumed  by the new
corporation,  if any,  resulting from any such  arrangement,  reorganization  or
readjustment,  and (ii) the rights of the holders of the Senior and Subordinated
Debt are not, without the consent of such holders,  altered by such arrangement,
reorganization  or readjustment.  The  consolidation of the Company with, or the
merger  of  the  Company  into,  another   corporation  or  the  liquidation  or
dissolution of the Company  following the conveyance or transfer of its property
as an entirety, or substantially as an entirety, to another corporation upon the
terms and  conditions  provided in Article 10 shall not be deemed a dissolution,
winding-up,  liquidation or  reorganization  for the purposes of this Section if
such  other  corporation  shall,  as  a  part  of  such  consolidation,  merger,
conveyance or transfer, comply with the conditions stated in Article 10. Nothing
in this Section  shall apply to claims of, or payments to, the Trustee  under or
pursuant to Article 7, except as provided therein. This Section shall be subject
to the further provisions of Section 14.05.

         SECTION 14.03.  Subrogation  of  Debentures.  Subject to the payment in
full of all Senior and Subordinated Debt, the holders of the Debentures shall be
subrogated  to the  rights of the  holders of Senior  and  Subordinated  Debt to
receive payments or distributions of cash, property or securities of the Company
applicable  to the  Senior and  Subordinated  Debt  until the  principal  of and
interest on the Debentures  shall be paid in full; and, for the purposes of such
subrogation,  no  payments  or  distributions  to the  holders of the Senior and
Subordinated  Debt of any cash,  property or  securities to which the holders of
the  Debentures or the Trustee on their behalf would be entitled  except for the
provisions  of this Article,  and no payment over pursuant to the  provisions of
this  Article to the holders of Senior and  Subordinated  Debt by holders of the
Debentures  or the Trustee on their behalf  shall,  as between the Company,  its
creditors other than holders of Senior and Subordinated  Debt and the holders of
the Debentures, be deemed to be a payment by the Company to or on account of the
Senior and Subordinated Debt; and no payments or distributions of cash, property
or  securities  to or for the  benefit of the  Debentureholders  pursuant to the
subrogation  provision of this Article,  which would otherwise have been paid to
the holders of Senior and  Subordinated  Debt shall be deemed to be a payment by
the Company to or for the account of the  Debentures.  It is understood that the
provisions  of this  Article  are and are  intended  solely  for the  purpose of
defining the relative rights of the holders of the Debentures,  on the one hand,
and the holders of the Senior and Subordinated Debt, on the other hand.

          Nothing contained in this Article or elsewhere in this Indenture or in
the  Debentures  is intended to or shall  impair,  as between the  Company,  its
creditors  other  than the  holders  of Senior and  Subordinated  Debt,  and the
holders of the Debentures,  the obligation of the Company, which is absolute and
unconditional,  to pay to the holders of the  Debentures  the  principal  of and
interest on the  Debentures as and when the same shall become due and payable in
accordance with their terms, or is intended to or shall affect




                                       71
<PAGE>

the  relative  rights of the  holders of the  Debentures  and  creditors  of the
Company other than the holders of the Senior and  Subordinated  Debt,  nor shall
anything herein or therein prevent the holder of any Debenture or the Trustee on
his behalf from  exercising all remedies  otherwise  permitted by applicable law
upon default under this  Indenture,  subject to the rights,  if any,  under this
Article  of the  holders  of Senior  and  Subordinated  Debt in respect of cash,
property or  securities  of the Company  received  upon the exercise of any such
remedy.

          Upon any payment or distribution of assets of the Company  referred to
in this Article,  the Trustee,  subject to the  provisions of Article 7, and the
holders of the  Debentures  shall be  entitled  to rely upon any order or decree
made  by  any  court  of  competent  jurisdiction  in  which  such  liquidation,
dissolution, winding up, receivership, reorganization, assignment or marshalling
proceedings  are  pending,  or  a  certificate  of  the  receiver,   trustee  in
bankruptcy,  liquidating  trustee,  agent or other person making such payment or
distribution,  delivered to the Trustee or to the holders of the Debentures, for
the  purpose  of  ascertaining  the  persons  entitled  to  participate  in such
distribution,  the  holders  of the  Senior  and  Subordinated  Debt  and  other
indebtedness of the Company,  the amount thereof or payable thereon,  the amount
or amounts paid or distributed  thereon and all other facts pertinent thereto or
to this Article.

          SECTION 14.04.  Authorization  by  Debentureholders.  Each holder of a
Debenture by his acceptance thereof authorizes the Trustee in his behalf to take
such action as may be necessary or appropriate  to effectuate the  subordination
provided in this Article and appoints the Trustee his  attorney-in-fact  for any
and all such purposes.

         SECTION 14.05. Notice to Trustee. The Company shall give prompt written
notice to the Trustee  and to any paying  agent of any fact known to the Company
which would prohibit the making of any payment of moneys to or by the Trustee or
any paying agent in respect of the Debentures pursuant to the provisions of this
Article.  Regardless  of anything to the  contrary  contained in this Article or
elsewhere in this Indenture,  the Trustee shall not be charged with knowledge of
the existence of any Senior and Subordinated  Debt or of any default or event of
default with respect to any Senior and  Subordinated  Debt or of any other facts
which would  prohibit  the making of any payment of moneys to or by the Trustee,
unless  and until the  Trustee  shall  have  received  notice in  writing at its
principal  Corporate  Trust  Office to that  effect  signed by an officer of the
Company, or by a holder or agent of a holder of Senior and Subordinated Debt who
shall  have been  certified  by the  Company  or  otherwise  established  to the
reasonable  satisfaction  of the Trustee to be such  holder or agent,  or by the
trustee under any indenture pursuant to which Senior and Subordinated Debt shall
be  outstanding,  and,  prior to the  receipt of any such  written  notice,  the
Trustee  shall,  subject to the  provisions  of Article 7, be entitled to assume
that no such facts  exist;  provided  that if on a date at least three  Business
days prior to the date upon  which by the terms  hereof  any such  moneys  shall
become payable for any purpose (including, without limitation, the payment




                                       72
<PAGE>

of the  principal of, or interest on any  Debenture)  the Trustee shall not have
received  with respect to such moneys the notice  provided for in this  Section,
then, regardless of anything herein to the contrary, the Trustee shall have full
power and  authority to receive such moneys and to apply the same to the purpose
for which they were  received,  and shall not be  affected  by any notice to the
contrary which may be received by it on or after such prior date.

          Regardless of anything to the contrary  herein,  nothing shall prevent
(a) any payment by the Company or the Trustee to the Debentureholders of amounts
in connection  with a redemption of Debentures if (i) notice of such  redemption
has been  given  pursuant  to Article 3 prior to the  receipt by the  Trustee of
written  notice as  aforesaid,  and (ii) such notice of  redemption is given not
earlier  than 60 days  before the  redemption  date,  or (b) any  payment by the
Trustee to the Debentureholders of amounts deposited with it pursuant to Article
11.

          The  Trustee  shall be  entitled  to rely on the  delivery  to it of a
written  notice by a person  representing  himself  to be a holder of Senior and
Subordinated Debt (or a trustee on behalf of such holder) to establish that such
notice has been given by a holder of Senior and  Subordinated  Debt or a trustee
on behalf of any such holder.  In the event that the Trustee  determines in good
faith that further  evidence is required with respect to the right of any person
as a holder of Senior and  Subordinated  Debt to  participate  in any payment or
distribution  pursuant to this  Article,  the Trustee may request such person to
furnish evidence to the reasonable  satisfaction of the Trustee as to the amount
of Senior and  Subordinated  Debt held by such person,  the extent to which such
person is entitled to participate in such payment or distribution  and any other
facts  pertinent  to the rights of such person under this  Article,  and if such
evidence  is not  furnished  the  Trustee  may defer any  payment to such person
pending  judicial  determination  as to the right of such person to receive such
payment.

          SECTION 14.06. Trustee's Relation to Senior and Subordinated Debt. The
Trustee and any agent of the Company or the Trustee shall be entitled to all the
rights set forth in this  Article  with  respect to any Senior and  Subordinated
Debt which may at any time be held by it in its individual or any other capacity
to the same  extent as any other  holder of  Senior  and  Subordinated  Debt and
nothing in this Indenture shall deprive the Trustee or any such agent, of any of
its rights as such holder.  Nothing in this Article shall apply to claims of, or
payments to, the Trustee under or pursuant to Article 7.

          With  respect  to the  holders of Senior and  Subordinated  Debt,  the
Trustee  undertakes  to  perform or to observe  only such of its  covenants  and
obligations  as are  specifically  set  forth in this  Article,  and no  implied
covenants or obligations  with respect to the holders of Senior and Subordinated
Debt shall be read into this  Indenture  against the Trustee.  The Trustee shall
not be  deemed  to  owe  any  fiduciary  duty  to  the  holders  of  Senior  and
Subordinated Debt and, subject to the provisions of Article 7, the Trustee shall



                                       73
<PAGE>

not be liable to any holder of Senior and Subordinated Debt if it shall pay over
or deliver to holders of  Debentures,  the Company or any other person moneys or
assets to which any holder of Senior and Subordinated  Debt shall be entitled by
virtue of this Article or otherwise.

          SECTION 14.07. No Impairment to Subordination. No right of any present
or future holder of any Senior and Subordinated Debt to enforce subordination as
herein  provided  shall at any time in any way be  prejudiced or impaired by any
act or  failure  to act on the part of the  Company  or by any act or failure to
act, in good faith, by any such holder,  or by any  noncompliance by the Company
with the terms,  provisions and covenants of this  Indenture,  regardless of any
knowledge thereof which any such holder may have or otherwise be charged with.

         The First  National  Bank of Chicago,  as Trustee,  hereby  accepts the
trust in this  Indenture  declared and provided,  upon the terms and  conditions
herein above set forth.

accompanied  by  evidence  satisfactory  to the Trustee  that the  overallotment
option has been  exercised.  The Series  5.50%  Debentures  shall mature and the
principal shall be due and payable together with all accrued and unpaid interest

form will be  payable,  the  transfer of such Series  5.50%  Debentures  will be

Company by check mailed to the registered holder at such address as shall appear
in the Debenture  register and that the payment of principal with respect to the
Series  5.50%  Debentures  will only be made upon  surrender of the Series 5.50%
Debentures  to the  Trustee.  Notwithstanding  the  foregoing,  so  long  as the
Property  Trustee  is the legal  owner and  record  holder of the  Series  5.50%
Debentures,  the payment of the principal of and interest (including  Compounded
Interest,  if any) on the Series 5.50%  Debentures held by the Property  Trustee

Declaration  of  Trust)  established  and  maintained  by the  Property  Trustee
pursuant to the Declaration of Trust.

         (b) In connection with a Dissolution Event:

              (i) Series 5.50% Debentures in certificated  form may be presented

         be  registered  in the  name of the  Depositary,  or its  nominee,  and
         delivered  by  the  Trustee  to the  Depositary  for  crediting  to the
         accounts  of  its  participants  pursuant  to the  instructions  of the
         Regular Trustees (as defined in the Declaration of Trust).  The Company
         upon  any  such   presentation   shall   execute  a  Global   Debenture
         representing  the Series 5.50%  Debentures in such aggregate  principal
         amount and  deliver  the same to the  Trustee  for  authentication  and
         delivery in accordance with the Indenture and this Second  Supplemental

              (ii)  if any  Preferred  Securities  are  held  in non  book-entry
         certificated  form, Series 5.50% Debentures in certificated form may be
         presented  to the Trustee by the  Property  Trustee  and any  Preferred
         Security  Certificate  (as defined in the  Declaration  of Trust) which
         represents Preferred Securities other than Preferred Securities held by
         the  Clearing  Agency (as defined in the  Declaration  of Trust) or its
         nominee  ("NON  BOOK-ENTRY  PREFERRED  SECURITIES")  will be  deemed to
         represent  beneficial interests in Series 5.50% Debentures presented to
         the  Trustee by the  Property  Trustee  having an  aggregate  principal
         amount equal to the aggregate  liquidation amount of the Non Book-Entry
         Preferred  Securities  until such Preferred  Security  Certificate  are
         presented to the  Debenture  Registrar  for transfer or  reissuance  at
         which time such Preferred  Security  Certificate will be canceled and a
         Series  5.50%  Debenture,  registered  in the name of the holder of the
         Preferred Security  Certificate or the transferee of the holder of such
         Preferred Security  Certificate,  as the case may be, with an aggregate
         principal  amount  equal to the  aggregate  liquidation  amount  of the
         Preferred Security Certificate canceled will be executed by the Company
         and  delivered  to the  Trustee  for  authentication  and  delivery  in
         accordance with the Indenture and this Second  Supplemental  Indenture.
         On issue of such Series 5.50% Debentures,  Series 5.50% Debentures with
         an  equivalent  aggregate  amount that were  presented  by the Property
         Trustee to the Trustee will be deemed to have been canceled.

         SECTION  1.03.  Each Series 5.50%  Debenture  will bear interest at the
rate of 5.50% per annum  from  October  29,  1997  until the  principal  thereof
becomes due and payable,  and on any overdue  principal  and (to the extent that
payment of such interest is  enforceable  under  applicable  law) on any overdue
installment  of  interest  at the same  rate per  annum,  compounded  quarterly,
payable (subject to the provisions of Article Three) quarterly in arrears on the
last day of each calendar quarter (each an "INTEREST  PAYMENT DATE",  commencing
on December 31, 1997),




                                       4
<PAGE>

to the person in whose  name such  Series  5.50%  Debenture  or any  predecessor
Series 5.50%  Debenture is  registered,  at the close of business on the regular
record date for such  interest  installment,  which,  except as set forth below,
shall be, in  respect  of any  Series  5.50%  Debentures  of which the  Property
Trustee is the registered holder of or a Global Debenture, the close of business
on the business day next preceding that Interest  Payment Date.  Notwithstanding
the foregoing sentence,  if the Preferred Securities are no longer in book-entry
only form or if pursuant to the  provisions of Section  2.11(c) of the Indenture
the Series 5.50%  Debentures  are not  represented  by a Global  Debenture,  the
regular  record  dates  for such  interest  installment  shall  be the  close of
business on the fifteenth  day of the month in which that Interest  Payment Date
occurs.  Any such interest  installment not punctually paid or duly provided for
shall  forthwith  cease to be payable to the registered  holders on such regular
record  date,  and may be paid to the  person  in whose  name the  Series  5.50%
Debenture (or one or more Predecessor  Debentures) is registered at the close of
business on a special  record date to be fixed by the Trustee for the payment of
such defaulted interest, notice whereof shall be given to the registered holders
of the  Series  5.50%  Debentures  not less than 10 days  prior to such  special
record  date,  or may be  paid  at any  time  in any  other  lawful  manner  not
inconsistent  with the  requirements  of any  securities  exchange  on which the
Series 5.50%  Debentures may be listed,  and upon such notice as may be required
by such exchange, all as more fully provided in the Indenture.

         The amount of  interest  payable for any period will be computed on the
basis of a 360-day year of twelve 30-day  months.  In the event that any date on
which interest is payable on the Series 5.50%  Debentures is not a business day,
then  payment  of  interest  payable  on such  date  will  be  made on the  next
succeeding  day which is a  business  day (and  without  any  interest  or other
payment in respect of any such delay),  except that,  if such business day is in
the next succeeding calendar year, such payment shall be made on the immediately
preceding  business  day, in each case with the same force and effect as if made
on such date.

         If at any time AES Trust II shall be required to pay any taxes, duties,
assessments or governmental  charges of whatever nature (other than  withholding
taxes)  imposed by the U.S.,  or any other taxing  authority,  then, in any such
case, the Company will pay as additional interest ("ADDITIONAL INTEREST") on the
Series 5.50% Debentures such additional amounts as shall be required so that the
net amounts  received  and retained by AES Trust II after paying any such taxes,
duties,  assessments or other governmental  charges will be equal to the amounts
AES Trust II would have  received  had no such taxes,  duties,  assessments,  or
other governmental charges been imposed.

         SECTION  1.04.  If  distributed  to holders of Preferred  Securities in
connection with a Dissolution  Event, the Series 5.50% Debentures will be issued




                                       5
<PAGE>

to such holders in the same form as the  Preferred  Securities  that such Series
5.50% Debentures replace in accordance with the following procedures:

         So  long  as  Series  5.50%  Debentures  are  eligible  for  book-entry
settlement with the Depositary,  or unless otherwise required by law, all Series
5.50%  Debentures  that are so eligible may be represented by one or more Series
5.50%  Debentures in global form registered in the name of the Depositary or the
nominee of the Depositary, except as otherwise specified below. The transfer and
exchange of  beneficial  interests in any such Series 5.50%  Debenture in global
form shall be effected  through the Depositary in accordance with this Indenture
and the procedures of the Depositary therefor.

         Series   5.50%   Debentures   that  are   distributed   to   "qualified
institutional  buyers"  within  the  meaning  of Rule  144A  ("QIBs")  under the
Securities Act of 1933, as amended (the  "Securities  Act") or to  institutional
"accredited  investors"  as defined in Rule  501(a)(1),(2),(3)  or (7)  ("IAIs")
under the Securities Act in replacement of Preferred Securities represented by a
global Preferred Security will be represented by one or more global Series 5.50%
Debentures  (the "144A  GLOBAL  DEBENTURE").  Series 5.50%  Debentures  that are
distributed  to  Non-U.S.   Persons  in  replacement  of  Preferred   Securities
represented  by a global  Preferred  Security will be represented by one or more
global Series 5.50% Debenture (the "REGULATION S GLOBAL DEBENTURE"). Each of the
144A Global Debenture and the Regulation S Global Debenture shall be referred to
herein as a Global  Debenture.  Series 5.50%  Debentures that are distributed to
QIBs,  IAIs  or  Non-U.S.  Persons  in  replacement  of  Certificated  Preferred
Securities  will be  represented  by definitive  Series 5.50%  Debentures as set
forth in this  Section  1.04.  If Global  Debentures  are issued,  transfers  of
interests in the Series 5.50%  Debentures  between the 144A Global Debenture and
the Regulation S Global  Debenture will be made in accordance  with the standing
instructions  and  procedures of the  Depositary  and its  participants  and the
Trustee shall make appropriate endorsements to reflect increases or decreases in
the principal amounts of such Global Debentures to reflect any such transfers.

         Except as provided below, beneficial owners of a Series 5.50% Debenture
in global form shall not be entitled to have  certificates  registered  in their
names,  will  not  receive  or be  entitled  to  receive  physical  delivery  of
certificates  in  definitive  form and will not be  considered  Holders  of such
Series 5.50% Debentures in global form.

              (i) Preferred  Securities  held in certificated  form,  except for
         certificates  representing  Preferred Securities held by the Depositary
         or its nominee (or any successor Clearing Agency or its nominee), shall
         upon  presentation  to the  Trustee by the  Property  Trustee or by the
         holder thereof



                                       6
<PAGE>

         or by the Property Trustee on behalf of such holders shall be exchanged
         for Series 5.50%  Debentures in fully registered  certificated  form of
         like aggregate principal amount and tenor.

         So long as the Series 5.50%  Debentures  are  eligible  for  book-entry
settlement,  and to the extent that Series 5.50%  Debentures are held by QIBs or
Non-U.S. Persons, as the case may be, in a Global Debenture, or unless otherwise
required by law, upon any transfer of a definitive  Series 5.50%  Debenture to a
QIB in  accordance  with Rule 144A or to a Non-U.S.  Person in  accordance  with
Regulation S, unless otherwise requested by the transferor,  and upon receipt of
the  definitive  Series 5.50%  Debentures  or Series 5.50%  Debentures  being so
transferred, together with a certification from the transferor that the transfer
is being made in  compliance  with Rule 144A or Regulation S, as the case may be
(or other  evidence  satisfactory  to the  Trustee),  the Trustee  shall make an
endorsement on any 144A Global  Debenture or any Regulation S Global  Debenture,
as the case may be, to reflect an increase in the aggregate  principal amount of
the Series  5.50%  Debentures  represented  by such  Global  Debenture,  and the
Trustee  shall cancel such  definitive  Series  5.50%  Debenture or Series 5.50%
Debentures in accordance  with the standing  instructions  and procedures of the
Depositary,   the  aggregate   principal   amount  of  Series  5.50%  Debentures
represented by such Global Debenture to be increased accordingly;  provided that
no definitive  Series 5.50% Debenture,  or portion thereof,  in respect of which
the Company or an Affiliate of the Company held any beneficial interest shall be
included in such Global  Debenture until such definitive  Series 5.50% Debenture
is freely  tradable in accordance  with Rule 144(k);  provided  further that the
Trustee  shall,  at the  written  request of the  Company,  issue  Series  5.50%
Debentures in definitive form upon any transfer of a beneficial  interest in the
Global Debenture to the Company or any Affiliate of the Company.

         Any Global  Debenture may be endorsed with or have  incorporated in the
text  thereof  such  legends or recitals or changes  not  inconsistent  with the
provisions  of this  Indenture  as may be  required  by the  Depositary,  by the
National  Association of Securities Dealers,  Inc. in order for the Series 5.50%
Debentures  to be tradeable  on the PORTAL  Market or as may be required for the
Series  5.50%  Debentures  to be tradeable  on any other  market  developed  for
trading of  securities  pursuant  to Rule 144A or  required  to comply  with any
applicable law or any regulation thereunder or with the rules and regulations of
any securities  exchange upon which the Series 5.50% Debentures may be listed or
traded or to conform  with any usage with  respect  thereto,  or to indicate any
special  limitations  or  restrictions  to which  any  particular  Series  5.50%
Debentures are subject.

         Each  Debenture  that bears or is required to bear the legend set forth
in  this  Section  1.04  (a  "RESTRICTED  SECURITY")  shall  be  subject  to the
restrictions on




                                       7

transfer  provided  in the legend set forth in this  Section  1.04,  unless such
restrictions  on transfer shall be waived by the written consent of the Company,
and the Holder of each Restricted Security, by such securityholder's  acceptance
thereof,  agrees to be bound by such  restrictions on transfer.  As used in this
Section 1.04, the terms  "transfer"  encompasses any sale,  pledge,  transfer or
other disposition of any Restricted Security.

         Prior to the Transfer  Restriction  Termination Date (as defined in the
Declaration of Trust),  any  certificate  evidencing a Series 5.50% Debenture or
Common  Stock  issued  upon the  conversion  or  exchange  of any  Series  5.50%
Debenture  shall  bear a legend in  substantially  the  following  form,  unless
otherwise agreed by the Company (with written notice thereof to the Trustee):

         THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S.  SECURITIES ACT OF
         1933, AS AMENDED (THE "SECURITIES ACT"), AND,  ACCORDINGLY,  MAY NOT BE
         OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING  SENTENCE.  BY ITS
         ACQUISITION  HEREOF,  THE  HOLDER  (1)  REPRESENTS  THAT  (A)  IT  IS A
         "QUALIFIED  INSTITUTIONAL  BUYER"  (AS  DEFINED  IN RULE 144A UNDER THE
         SECURITIES  ACT), (B) IT IS AN INSTITUTIONAL  "ACCREDITED  INVESTOR" IN
         RULE  501(a)(1),   (2),  (3)  OR  (7)  UNDER  THE  SECURITIES  ACT  (AN
         "INSTITUTIONAL  ACCREDITED INVESTOR")),  OR (C) IT IS NOT A U.S. PERSON
         AND IS ACQUIRING  THIS SECURITY IN AN OFFSHORE  TRANSACTION  (2) AGREES
         THAT  IT  WILL  NOT  PRIOR  TO THE  EXPIRATION  OF THE  HOLDING  PERIOD

         UNDER  THE  SECURITIES  ACT (OR ANY  SUCCESSOR  PROVISION),  RESELL  OR
         OTHERWISE  TRANSFER THIS SECURITY  EXCEPT (A) TO AES OR ANY  SUBSIDIARY
         THEREOF,  (B)  INSIDE THE UNITED  STATES TO A  QUALIFIED  INSTITUTIONAL
         BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) INSIDE
         THE UNITED STATES TO AN INSTITUTIONAL  ACCREDITED INVESTOR THAT, BEFORE
         SUCH TRANSFER  FURNISHES THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN
         REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER
         OF THIS  SECURITY  (THE FORM OF WHICH  LETTER CAN BE OBTAINED  FROM THE
         TRUSTEE) AND IF SUCH  TRANSFER IS IN RESPECT OF AN AGGREGATE  PRINCIPAL
         AMOUNT OF SECURITIES




                                       8

         LESS THAN $250,000,  AN OPINION OF COUNSEL ACCEPTABLE TO THE TRUST THAT
         SUCH TRANSFER IS IN COMPLIANCE WITH THE SECURITIES ACT, (D) OUTSIDE THE
         UNITED STATES IN AN OFFSHORE  TRANSACTION  IN COMPLIANCE  WITH RULE 904
         UNDER  THE   SECURITIES   ACT,  (E)  PURSUANT  TO  THE  EXEMPTION  FROM
         REGISTRATION  PROVIDED  BY  RULE  144  UNDER  THE  SECURITIES  ACT  (IF
         AVAILABLE) OR (F) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER
         THE  SECURITIES  ACT AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON
         TO WHOM THIS  SECURITY IS  TRANSFERRED  A NOTICE  SUBSTANTIALLY  TO THE
         EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF THIS SECURITY
         PRIOR TO THE EXPIRATION DATE OF THE HOLDING PERIOD  APPLICABLE TO SALES
         OF THE SECURITY EVIDENCED HEREBY UNDER RULE 144(k) UNDER THE SECURITIES
         ACT (OR  ANY  SUCCESSOR  PROVISION),  THE  TRANSFEROR  MUST  CHECK  THE
         APPROPRIATE  BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER
         OF SUCH TRANSFER AND SUBMIT THIS  CERTIFICATE TO THE PROPERTY  TRUSTEE.
         IF THE PROPOSED TRANSFEREE IS AN INSTITUTIONAL ACCREDITED INVESTOR, THE
         TRANSFEROR  MUST,  BEFORE  SUCH  TRANSFER,  FURNISH TO THE ISSUER  SUCH
         CERTIFICATIONS,   LEGAL  OPINIONS  OR  OTHER   INFORMATION  AS  IT  MAY
         REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT
         TO  AN  EXEMPTION  FROM  OR  IN  A  TRANSACTION  NOT  SUBJECT  TO,  THE
         REGISTRATION  REQUIREMENTS OF THE SECURITIES  ACT. AS USED HEREIN,  THE
         TERMS "OFFSHORE  TRANSACTION",  "UNITED STATES" AND "U.S.  PERSON" HAVE
         THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

         Following the Transfer  Restriction  Termination  Date or the sale of a
Debenture or Common Stock issued upon the  conversion or exchange of a Debenture
pursuant to an effective  registration  statement or Rule 144 (or any  successor
provision)  under the  Securities  Act,  any  Debenture  or  security  issued in
exchange  or  substitution  therefor  (other  than (i) Series  5.50%  Debentures
acquired by the  Company or any  Affiliate  thereof  since the issue date of the
Preferred  Securities  and (ii)  Common  Stock  issued  upon the  conversion  or
exchange of any



                                       9
<PAGE>

Debenture  described in clause (i) above) may upon  surrender of such  Debenture
for exchange to the  Debenture  Registrar in accordance  with the  provisions of
this Section 1.04, be exchanged for a new Debenture or Series 5.50%  Debentures,
of like  tenor  and  aggregate  principal  amount,  which  shall  not  bear  the
restrictive legend required by this Section 1.04.

         Notwithstanding  any other  provisions of the Indenture (other than the
provisions  set  forth in this  Section  1.04),  a Global  Debenture  may not be
transferred  as a whole except by the  Depositary to a nominee of the Depositary
or by a nominee of the  Depositary  to the  Depositary  or another  nominee to a
successor Depositary or a nominee of such successor Depositary.

         The Depositary shall be a clearing agency registered under the Exchange
Act. The Company  initially  appoints  The  Depository  Trust  Company to act as
Depositary  with  respect  to  the  Series  5.50%  Debentures  in  global  form.
Initially,  the Global Debentures shall be issued to the Depositary,  registered
in the name of Cede & Co., as the nominee of the Depositary,  and deposited with
the Trustee as custodian for Cede & Co.

         If at any time the  Depositary for the Global  Debentures  notifies the
Company that it is unwilling or unable to continue as Depositary for such Series
5.50% Debentures, the Company may appoint a successor Depositary with respect to
such Series 5.50%  Debentures.  If a successor  Depositary  for the Series 5.50%
Debentures  is not  appointed  by the  Company  within 90 days after the Company
receives such notice, the Company will execute, and the Trustee, upon receipt of
an  Officers'  Certificate  for  authentication  and  delivery  of Series  5.50%
Debentures, will authenticate and deliver, Series 5.50% Debentures in definitive
form,  in an aggregate  principal  amount equal to the  principal  amount of the
Global Debentures, in exchange for such Global Debentures.

         Definitive Series 5.50% Debentures issued in exchange for all or a part
of a Global Debenture  pursuant to this Section 1.04 shall be registered in such
names  and in such  authorized  denominations  as the  Depositary,  pursuant  to
instructions  from its  direct or  indirect  participants  or  otherwise,  shall
instruct the Trustee.  Upon  execution  and  authentication,  the Trustee  shall
deliver such  definitive  Series 5.50%  Debentures  to the person in whose names
such definitive Series 5.50% Debentures are so registered.

         At such time as all interests in a Global Debenture have been redeemed,
converted,  exchanged,  repurchased or canceled, such Global Debenture shall be,
upon  receipt  thereof,  canceled by the  Trustee in  accordance  with  standing
procedures  and  instructions  of the  Depositary.  At any  time  prior  to such
cancellation, if any interest in a Global Debenture is exchanged for definitive



                                       10
<PAGE>

Series  5.50%  Debentures,  redeemed  by the  Company  pursuant  to Article 2 or
canceled, or transferred for part of a Global Debenture, the principal amount of
such Global  Debenture  shall,  in accordance  with the standing  procedures and
instructions of the Depositary be reduced or increased,  as the case may be, and
an  endorsement  shall be made on such Global  Debenture by, or at the direction
of, the Trustee to reflect such reduction or increase. Following such redemption
by the  Company or  cancellation,  or  transfer,  the Company  will  execute and
Trustee will  authenticate and make available for delivery to the transferee (or
such transferee's  nominee, as the case may be), a Series 5.50% Debenture in the
appropriate  aggregate  principal amount and bearing such restrictive legends as
may be required by this Indenture.

         Any Series 5.50%  Debenture or Common Stock issued upon the  conversion
or exchange of a Series 5.50% Debenture that, prior to the Transfer  Restriction
Termination  Date, is purchased or owned by the Company or any Affiliate thereof
may not be resold by the Company or such Affiliate  unless  registered under the
Securities  Act  or  resold  pursuant  to an  exemption  from  the  registration
requirements of the Securities Act in a transaction which results in such Series
5.50%  Debentures  or  Common  Stock,  as the  case  may  be,  no  longer  being
"restricted securities" (as defined under Rule 144).



                                    ARTICLE 2
               OPTIONAL REDEMPTION OF THE SERIES 5.50% DEBENTURES

         SECTION  2.01.  Except as provided  in Section  2.02 and subject to the
provisions  below,  Series 5.50%  Debentures  may not be redeemed by the Company
prior to  September  30,  2000.  Subject  to the terms of  Article  Three of the
Indenture,  the  Company  shall  have  the  right to  redeem  the  Series  5.50%
Debentures,  in whole or in part,  from time to time, on or after  September 30,
2000,  upon not less than 30 nor more than 60 days  notice to the  Holder of the
Series 5.50%  Debentures,  at the following prices  (expressed as percentages of
the principal amount of the Series 5.50%  Debentures) (the "OPTIONAL  REDEMPTION
PRICE"),  together  with any  accrued  and unpaid  interest  thereon,  including
Compounded Interest (as defined herein), if any, to, but excluding,  the date of
such redemption, if redeemed during the 12-month period beginning September 30.

and 100% if redeemed on or after September 30, 2005.

         If the Series 5.50%  Debentures  are  redeemed on any Interest  Payment
Date,  accrued and unpaid  interest shall be payable to Holders of record on the
relevant record date.

         The  Company  may not  redeem  any Series  5.50%  Debenture  unless all
accrued and unpaid interest thereon,  including Compounded Interest, if any, has
been  paid  for all  quarterly  periods  terminating  on or prior to the date of
notice  of  redemption.  So  long  as the  corresponding  Trust  Securities  are
outstanding,  the proceeds from the  redemption  of the Series 5.50%  Debentures
will be used to redeem the Trust Securities.

         If the  Company  gives a notice  of  redemption  in  respect  of Junior
Subordinated Debentures (which notice will be irrevocable), then, by 12:00 noon,
New York City time, on the redemption date, the Company will deposit irrevocably
with the Indenture  Trustee funds  sufficient to pay the  applicable  Redemption
Price  and  will  give  irrevocable  instructions  and  authority  to  pay  such
Redemption Price to the holders of the Junior Subordinated Debentures.

         If any date fixed for redemption of Junior  Subordinated  Debentures is
not a Business  Day, then payment of the  Redemption  Price payable on such date
will be made on the next  succeeding day that is a Business Day (and without any
interest or other  payment in respect of any such delay)  except  that,  if such
Business Day falls in the next calender  year,  such payment will be made on the
immediately  preceding Business Day, in each case with the same force and effect
as if made on such date fixed for redemption.

         In the  event of any  redemption  in part,  the  Company  shall  not be
required  to  (i)  issue,  register  the  transfer  of or  exchange  any  Junior
Subordinated  Debentures during a period beginning at the opening of business 15
days before any selection for redemption of Junior  Subordinated  Debentures and
ending at the  close of  business  on the  earliest  date on which the  relevant
notice of  redemption  is deemed to have  been  given to all  holders  of Junior
Subordinated  Debentures  to be redeemed  and (ii)  register  the transfer of or
exchange any Junior Subordinated



                                       12
<PAGE>



Debentures  so  selected  for  redemption,  in  whole  or in  part,  except  the
unredeemed portion of any Junior Subordinated Debentures being redeemed in part.

         SECTION  2.02.  If, at any time,  a Tax Event (as defined  below) shall
occur or be continuing  and (i) the Regular  Trustees and the Company shall have
received an opinion (a  "REDEMPTION  TAX  OPINION") of a  nationally  recognized
independent  tax counsel  experienced in such matters that, as a result of a Tax
Event,  there is more  than an  insubstantial  risk  that the  Company  would be
precluded from deducting the interest on the Series 5.50%  Debentures for United
States  federal  income tax purposes  even if the Series 5.50%  Debentures  were
distributed  to the holders of Preferred  Securities  and Common  Securities  in
liquidation  of such  holder's  interest  in AES  Trust  II as set  forth in the
Declaration  of Trust or (ii) the Regular  Trustees  shall have been informed by
such tax counsel  that a No  Recognition  Opinion (as defined  below)  cannot be
delivered  to AES Trust II, the Company  shall have the right at any time,  upon
not less  than 30 nor more than 60 days'  notice,  to redeem  the  Series  5.50%
Debentures  in  whole  or in  part  for  cash at a  price  equal  to 100% of the
principal amount thereof, together with any accrued and unpaid interest thereon,
including Compounded Interest, if any, to, but excluding the date of redemption,
within 90 days  following the occurrence of such Tax Event;  provided,  however,
that,  if at the time there is available to the Company or the Regular  Trustees
on behalf of AES  Trust II the  opportunity  to  eliminate,  within  such 90 day
period, the Tax Event by taking some ministerial action ("MINISTERIAL  ACTION"),
such as filing a form or making an  election,  or  pursuing  some other  similar
reasonable measure,  which has no adverse effect on AES Trust II, the Company or
the holders of the Preferred Securities,  the Company or the Regular Trustees on
behalf  of AES Trust II will  pursue  such  measure  in lieu of  redemption  and
provided further that the Company shall have no right to redeem the Series 5.50%
Debentures while the Regular Trustees on behalf of AES Trust II are pursuing any
such Ministerial Action.

         "TAX EVENT" means that the Company and the Regular  Trustees shall have
obtained an opinion of nationally recognized independent tax counsel experienced
in such  matters (a  "DISSOLUTION  TAX  OPINION") to the effect that on or after
October 23, 1997 as a result of (a) any amendment to, or change in, the laws (or
any regulations thereunder) of the United States or any political subdivision or
taxing  authority  thereof or therein,  (b) any  amendment  to, or change in, an
interpretation or application of any such laws or regulations by any legislative
body,  court,   governmental  agency  or  regulatory  authority  (including  the
enactment of any  legislation  and the  publication of any judicial  decision or
regulatory determination), (c) any interpretation or pronouncement that provides
for a position  with respect to such laws or  regulations  that differs from the
theretofore  generally  accepted  position  or  (d)  any  action  taken  by  any
governmental  agency  or  regulatory  authority,  which  amendment  or change is
enacted, promulgated, issued



                                       13
<PAGE>

or effective or which  interpretation or pronouncement is issued or announced or
which action is taken,  in each case on or after  October 23, 1997 there is more
than an  insubstantial  risk that (i) AES Trust II is, or will be within 90 days
of the date thereof, subject to United States federal income tax with respect to
income accrued or received on the Series 5.50% Debentures, (ii) AES Trust II is,
or will be within 90 days of the date thereof, subject to more than a de minimis
amount of taxes, duties or other governmental  charges or (iii) interest payable
by the Company to AES Trust II on the Series 5.50%  Debentures is not, or within
90 days of the date  thereof will not be,  deductible  by the Company for United
States federal income tax purposes.

         "NO  RECOGNITION  OPINION" means an opinion of a nationally  recognized
independent tax counsel  experienced in such matters,  which opinion may rely on
any then applicable published revenue ruling of the Internal Revenue Service, to
the effect that the holders of the Preferred  Securities  will not recognize any
gain or loss for United  States  federal  income tax  purposes  as a result of a
dissolution of AES Trust II and  distribution of the Series 5.50%  Debentures as
provided in the Declaration of Trust.

         SECTION  2.03.  If the  Series  5.50%  Debentures  are  only  partially
redeemed  pursuant to this  Article Two,  the Series  5.50%  Debentures  will be
redeemed  pro rata or by lot or by any other  method  utilized  by the  Trustee,
provided  that if at the time of  redemption,  the Series 5.50%  Debentures  are
registered as a Global  Debenture,  the  Depository  shall  determine by lot the
principal  amount of such Series 5.50%  Debentures held by each Debenture Holder
to be redeemed in accordance with its customary procedures.  Notwithstanding the
foregoing,  if a partial  redemption of the Series 5.50% Debentures would result
in the delisting of the Preferred Securities by any national securities exchange
or other  organization  on which the Preferred  Securities are then listed,  the
Company shall not be permitted to effect such partial  redemption  and will only
redeem the Series 5.50% Debentures in whole.


                                    ARTICLE 3
                      EXTENSION OF INTEREST PAYMENT PERIOD

         SECTION  3.01.  So long as the Company is not in default in the payment
of interest on the Series 5.50% Debentures, the Company shall have the right, at
any time during the term of the Series  5.50%  Debentures,  from time to time to
extend the interest  payment period of such Series 5.50% Debentures for up to 20
consecutive quarterly interest periods (the "EXTENDED INTEREST PAYMENT PERIOD"),
at the end of which period the Company shall pay all interest accrued



                                       14
<PAGE>

and unpaid  thereon  (together  with  interest  thereon at the rate of 5.50% per
annum  to  the  extent  permitted  by  applicable  law,   compounded   quarterly
("COMPOUNDED INTEREST"));  provided that no Extended Interest Payment Period may
extend  beyond  the  Maturity  Date  or  redemption  date  of the  Series  5.50%
Debentures.  During such Extended  Interest Payment Period the Company shall not
declare  or pay  any  dividend  on,  or  redeem,  purchase,  acquire  or  make a
distribution or liquidation  payment with respect to, any of its common stock or
preferred stock or make any guarantee  payments with respect  thereto;  provided
that the foregoing will not apply to any stock  dividends paid by the Company in
Common Stock.  Prior to the  termination of any such Extended  Interest  Payment
Period,  the Company may pay all or any portion of the  interest  accrued on the
Series 5.50% Debentures on any Interest Payment Date to holders of record on the
regular record date for such Interest  Payment Date or from time to time further
extend such Period;  provided  that such Period  together  with all such further
extensions  thereof shall not exceed 20 consecutive  quarterly interest periods.
Upon the  termination  of any  Extended  Interest  Payment  Period  and upon the
payment of all accrued and unpaid  interest then due,  together with  Compounded
Interest, the Company may select a new Extended Interest Payment Period, subject
to the foregoing  requirements.  No interest  shall be due and payable during an
Extended Interest Payment Period,  except at the end thereof.  At the end of the
Extended  Interest Payment Period the Company shall pay all interest accrued and
unpaid on the Series 5.50%  Debentures  including any Compounded  Interest which
shall be payable to the holders of the Series  5.50%  Debentures  in whose names
the Series 5.50%  Debentures  are  registered in the  Debenture  register on the
first record date after the end of the Extended Interest Payment Period.

         SECTION  3.02.  (a) So long as the Property  Trustee is the legal owner
and holder of record of the Series  5.50%  Debentures,  at the time the  Company
selects an Extended  Interest  Payment  Period,  the Company shall give both the
Property  Trustee  and the  Trustee  written  notice  of its  selection  of such
Extended  Interest  Payment  Period one business day prior to the earlier of (i)
the next succeeding date on which distributions on the Preferred  Securities are
payable or (ii) the date AES Trust II is  required  to give notice of the record
date or the date such  distributions  are  payable to  holders of the  Preferred
Securities, but in any event not less than one business day prior to such record
date.  The  Company  shall  cause AES Trust II to give  notice of the  Company's
selection  of such  Extended  Interest  Payment  Period  to the  holders  of the
Preferred Securities.

         (b) If as a result of a Dissolution  Event Series 5.50% Debentures have
been distributed to holders of Preferred  Securities and Common  Securities,  at
the time the Company selects an Extended  Interest  Payment Period,  the Company
shall give the holders of the Series 5.50%  Debentures  and the Trustee  written
notice of its selection of such Extended Interest Payment Period at least 10



                                       15
<PAGE>

business days prior to the earlier of (i) the next succeeding  Interest  Payment
Date or (ii) the date the  Company is  required  to give notice of the record or
payment date of such  interest  payment to the New York Stock  Exchange or other
applicable  self-regulatory  organization  or to  holders  of the  Series  5.50%
Debentures.

         SECTION  3.03.  The  quarter in which any notice is given  pursuant  to
Section  3.02 shall be counted as one of the  quarters  permitted in the maximum
Extended Interest Payment Period permitted under this Article Three.


                                    ARTICLE 4
                 COVENANTS APPLICABLE TO SERIES 5.50% DEBENTURES

         SECTION 4.01. So long as any Preferred  Securities remain  outstanding,
the  Company  will not  declare or pay any  dividends  on, or redeem,  purchase,
acquire or make a distribution  or  liquidation  payment with respect to, any of
its common stock or preferred stock or make any guarantee  payments with respect
thereto if at such time (i) the Company  shall be in default with respect to its
Guarantee  Payments (as defined in the  Guarantee  Agreement)  or other  payment
obligations  under the Guarantee  Agreement,  (ii) there shall have occurred any
Event of Default under the Indenture with respect to the Series 5.50% Debentures
or (iii) the  Company  shall have given  notice of its  election  of an Extended
Interest  Payment  Period  and  such  Period,  or  any  extension  thereof,   is
continuing;  provided that the foregoing  will not apply to any stock  dividends
paid by the Company in Common Stock.

         SECTION 4.02. In connection  with the  distribution of the Series 5.50%
Debentures to the holders of the Preferred  Securities upon a Dissolution Event,
the Company will use its best efforts to list such Series  5.50%  Debentures  on
the  New  York  Stock  Exchange  or on  such  other  exchange  as the  Preferred
Securities are then listed and traded.

         SECTION 4.03.  The Company  covenants and agrees for the benefit of the
holders of the Preferred  Securities to comply fully with all of its obligations
and agreements under the Declaration of Trust,  including,  without  limitation,
its obligations under Article 4 thereof.

         SECTION 4.04.  Prior to the  distribution of Series 5.50% Debentures to
the  holders of  Preferred  Securities  upon a  Dissolution  Event,  the Company
covenants and agrees for the benefit of the holders of the Preferred  Securities
(i) not to cause or permit the Common Securities to be transferred except as



                                       16
<PAGE>

permitted  by the  Declaration  of Trust  and (ii)  that it will use  reasonable
efforts to cause the Trust to  continue  to be  treated  as a grantor  trust for
United  States  federal  income  tax  purposes,  except  in  connection  with  a
distribution  of the Series 5.50%  Debentures as provided in the  Declaration of
Trust.


                                    ARTICLE 5
                            CONVERSION OF DEBENTURES

         SECTION 5.01.  Subject to and upon  compliance  with the  provisions of
this Article Five, the Series 5.50%  Debentures are convertible at the option of
the Holder, at any time through the close of business on September 30, 2012 (or,
in the case of Series 5.50% Debentures called for redemption, prior to the close
of business on the Business Day prior to the corresponding redemption date) into
fully paid and nonassessable shares of Common Stock of the Company at an initial
conversion  rate of  0.8914  shares of  Common  Stock for each $50 in  aggregate
principal  amount of Series 5.50%  Debentures  (equal to a conversion  price (as
adjusted  from time to time,  the  "CONVERSION  PRICE")  of $56.09  per share of
Common Stock), subject to adjustment as described in this Article Five. A Holder
of Series 5.50%  Debentures  may convert any portion of the principal  amount of
the Series 5.50%  Debentures  into that number of fully paid and nonas  sessable
shares of Common Stock  obtained by dividing the principal  amount of the Series
5.50%  Debentures to be converted by such  conversion  price.  All  calculations
under this  Article  Five shall be made to the  nearest  cent or to the  nearest
1/100th of a share, as the case may be.

         SECTION  5.02.  (a) In order to convert  all or a portion of the Series
5.50%  Debentures,  the Holder thereof shall deliver to the Conversion  Agent an
irrevocable  Notice of Conversion  setting forth the principal  amount of Series
5.50% Debentures to be converted, together with the name or names, if other than
the Holder, in which the shares of Common Stock should be issued upon conversion
and, if such Series 5.50%  Debentures  are definitive  Series 5.50%  Debentures,
surrender to the Conversion  Agent the Series 5.50%  Debentures to be converted,
duly endorsed or assigned to the Company or in blank.  In addition,  a holder of
Preferred  Securities  may exercise its right under the  Declaration of Trust to
convert  such  Preferred  Securities  into  Common  Stock by  delivering  to the
Conversion  Agent  an  irrevocable   Notice  of  Conversion  setting  forth  the
information  called for by the preceding  sentence and directing the  Conversion
Agent to (i) exchange such Preferred  Security for a portion of the Series 5.50%
Debentures  held by the Trust (at an exchange  rate of $50  principal  amount of
Series 5.50% Debenture for each Preferred Security) and (ii) immediately convert
such Series 5.50% Debenture,  on behalf of such holder, into Common Stock of



                                       17
<PAGE>

the Company pursuant to this Article Five and, if such Preferred  Securities are
in definitive form,  surrendering  such Preferred  Securities,  duly endorsed or
assigned to the Company or in blank.  So long as any  Preferred  Securities  are
outstanding,  the Trust  shall not  convert any Series  5.50%  Debenture  except
pursuant to a Notice of Conversion delivered to the Conversion Agent by a holder
of  Preferred  Securities.  Any  reference  herein to a  "HOLDER"  of  Preferred
Securities  shall  mean  a  "HOLDER"  of  such  securities  as  defined  in  the
Declaration of Trust.

         If a Preferred  Security is surrendered for conversion  after the close
of business on any regular record date for payment of a Distribution  and before
the opening of business on the  corresponding  Distribution  payment date, then,
notwithstanding  such conversion,  the Distribution payable on such Distribution
payment  date will be paid in cash to the person in whose name the Series  5.50%
Debenture is registered at the close of business on such record date, and (other
than a Series 5.50%  Debenture or a portion of a Series 5.50%  Debenture  called
for redemption on a redemption  date occurring  after such record date and on or
prior to such Distribution payment date) when so surrendered for conversion, the
Series 5.50%  Debenture must be accompanied by payment of an amount equal to the
Distribution  payable on such  Distribution  payment  date.  Except as otherwise
provided in the immediately  preceding sentence, in the case of any Series 5.50%
Debenture which is converted,  interest whose Maturity Date is after the date of
conversion of such Series 5.50% Debenture shall not be payable,  and the Company
shall  not make  nor be  required  to make  any  other  payment,  adjustment  or
allowance  with  respect to  accrued  but unpaid  interest  on the Series  5.50%
Debenture  being  converted,  which  shall be  deemed  to be paid in full.  Each
conversion shall be deemed to have been effected  immediately prior to the close
of  business  on the day on which the Notice of  Conversion  was  received  (the
"CONVERSION  DATE") by the Conversion  Agent from the Holder or from a holder of
the  Preferred  Securities  effecting  a  conversion  thereof  pursuant  to  its
conversion  rights  under the  Declaration,  as the case may be.  The  Person or
Persons entitled to receive the Common Stock issuable upon such conversion shall
be treated for all purposes as the record holder or holders of such Common Stock
as of the Conversion Date. As promptly as practicable on or after the Conversion
Date, the Company shall issue and deliver at the office of the Conversion Agent,
unless  otherwise  directed  by  the  Holder  in the  Notice  of  Conversion,  a
certificate  or  certificates  for the  number of full  shares  of Common  Stock
issuable upon such conversion,  together with the cash payment,  if any, in lieu
of any  fraction  of any share to the Person or Persons  entitled to receive the
same. The Conversion  Agent shall deliver such  certificate or  certificates  to
such Person or Persons.

         (b) The  Company's  delivery  upon  conversion  of the fixed  number of
shares of Common Stock into which the Series 5.50%  Debentures  are  convertible



                                       18
<PAGE>

(together with the cash payment,  if any, in lieu of fractional shares) shall be
deemed to  satisfy  the  Company's  obligation  to pay the  principal  amount at
maturity of the portion of Series 5.50%  Debentures  so converted and any unpaid
interest (including Compounded Interest) accrued on such Series 5.50% Debentures
at the time of such conversion.

         (c) No fractional  shares of Common Stock will be issued as a result of
conversion, but in lieu thereof, the Company shall pay to the Conversion Agent a
cash  adjustment in an amount equal to the same fraction of the Closing Price of
such fractional  interest on the date on which the Series 5.50%  Debentures were
duly surrendered to the Conversion Agent for conversion,  or, if such day is not
a day on which any securities are traded on the national  securities exchange or
quotation  system used to determine the Closing Price (a "TRADING  DAY"), on the
next Trading Day, and the  Conversion  Agent in turn will make such payment,  if
any, to the Holder of the Series 5.50% Debentures or the holder of the Preferred
Securities so converted.

         (d) In the event of the  conversion  of any Series  5.50%  Debenture in
part only, a new Series  5.50%  Debenture  or Series  5.50%  Debentures  for the
unconverted  portion  thereof  will be issued in the name of the Holder  thereof
upon the cancellation thereof in accordance with Section 2.05 of the Indenture.

         (e) In effecting the conversion  transactions described in this Section
5.02,  the  Conversion  Agent is acting  as agent of the  holders  of  Preferred
Securities (in the exchange of Preferred Securities for Series 5.50% Debentures)
and as agent of the Holders of Series 5.50%  Debentures  (in the  conversion  of
Series 5.50%  Debentures into Common Stock),  as the case may be. The Conversion
Agent is hereby  authorized (i) to exchange Series 5.50%  Debentures held by the
Trust  from  time to time  for  Preferred  Securities  in  connection  with  the
conversion of such Preferred Securities in accordance with this Article Five and
(ii) to convert  all or a portion of the Series  5.50%  Debentures  into  Common
Stock and  thereupon to deliver such shares of Common Stock in  accordance  with
the  provisions  of this  Article  Five and to deliver to the Trust a new Series
5.50%  Debenture  or  Series  5.50%  Debentures  for any  resulting  unconverted
principal amount.

         SECTION 5.03.   (a) The Conversion Price shall be adjusted from time to
time as follows:

              (i) In case the  Company  shall  pay or make a  dividend  or other
         distribution  on  Common  Stock in shares  of  Common  Stock,  then the
         Conversion  Price in  effect  at the  opening  of  business  on the day
         following the date fixed for the determination of shareholders entitled
         to receive such



                                       19
<PAGE>

         dividend or other  distribution  shall be reduced by  multiplying  such
         Conversion  Price by a fraction  the  numerator  of which  shall be the
         number of shares of Common Stock  outstanding  at the close of business
         on the date fixed for such  determination  and the denominator of which
         shall be the sum of such  number  of  shares  and the  total  number of
         shares constituting such dividend or other distribution, such reduction
         to become  effective  immediately  after the opening of business on the
         day following the date fixed for such  determination.  For the purposes
         of this  subparagraph  (i), the number of shares of Common Stock at any
         time  outstanding  shall not include shares held in the treasury of the
         Company  (except to the extent such dividend or  distribution  is being
         made with respect to such shares) but shall include shares  issuable in
         respect of scrip certificates  issued in lieu of fractions of shares of
         Common Stock.

              (ii) In case the  outstanding  shares  of  Common  Stock  shall be
         subdivided  into a greater  number of shares of Common Stock,  then the
         Conversion  Price in  effect  at the  opening  of  business  on the day
         following the day upon which such subdivision  becomes  effective shall
         be proportionately  reduced,  and, conversely,  in case the outstanding
         shares of  Common  Stock  shall be  combined  into a smaller  amount of
         shares  of Common  Stock,  then the  Conversion  Price in effect at the
         opening  of  business  on the day  following  the day upon  which  such
         combination becomes effective shall be proportionately  increased, such
         reduction  or  increase,  as the  case  may  be,  to  become  effective
         immediately  after the opening of business on the day following the day
         upon which such subdivision or combination becomes effective.

              (iii) In case the Company  shall  issue  rights or warrants to all
         holders of Common Stock entitling them (for a period expiring within 45
         days after the record date fixed for a  distribution  of such rights or
         warrants)  to  subscribe  for or purchase  shares of Common  Stock at a
         price per share  less than the  Current  Market  Price (as  hereinafter
         defined) per share (determined as provided in subparagraph (vii) below)
         of Common Stock on the date fixed for the determination of shareholders
         entitled to receive such rights or warrants  (other than  pursuant to a
         dividend reinvestment plan), then the Conversion Price in effect at the
         opening  of  business  on the day  following  the date  fixed  for such
         determination  shall be reduced by multiplying such Conversion Price by
         a  fraction  the  numerator  of which  shall be the number of shares of
         Common Stock outstanding at the close of business on the date fixed for
         such determination plus the number of shares of Common Stock which the
         aggregate of the offering price of the total number of shares of Common
         Stock so offered for  subscription  or purchase  would purchase at such



                                       20
<PAGE>

         Current Market Price and the denominator  shall be the number of shares
         of Common Stock  outstanding at the close of business on the date fixed
         for such  determination  plus the  number of shares of Common  Stock so
         offered  for  subscription  or  purchase,   such  reduction  to  become
         effective  immediately  after  the  opening  of  business  on  the  day
         following  the date fixed for such  determination.  For the purposes of
         this  subparagraph  (iii),  the number of shares of Common Stock at any
         time  outstanding  shall not include shares held in the treasury of the
         Company  but  shall  include  shares   issuable  in  respect  of  scrip
         certificates issued in lieu of fractions of shares of Common Stock. The
         Company agrees not to issue any rights or warrants in respect of shares
         of Common Stock held in the treasury of the Company. To the extent that
         shares of Common Stock are not delivered  after the  expiration of such
         rights or warrants,  the  Conversion  Price shall be  readjusted to the
         Conversion Price which would then be in effect had the adjustments made
         in respect of the issuance of such rights or warrants  been made on the
         basis of delivery of only the number of shares of Common Stock actually
         delivered.

         (iv) Subject to the second paragraph of this subparagraph (iv), in case
         the Company shall, by dividend or otherwise,  distribute to all holders
         of Common Stock (A) shares of capital stock of the Company  (other than
         Common Stock),  (B) evidence of  indebtedness of the Company and/or (C)
         other assets  (including  securities,  but  excluding (1) any rights or
         warrants  referred to in  subparagraph  (iii) above,  (2) any rights or
         warrants to obtain capital stock of a company other than the Company or
         any subsidiary of the Company  (including  any rights  offerings of the
         Company with respect to capital stock of companies in which the Company
         has  an   investment   (a  "RIGHTS   OFFERING")),   (3)   dividends  or
         distributions  in  connection  with  the  liquidation,  dissolution  or
         winding-up of the Company,  (4) dividends  payable  solely in cash that
         may from time to time be fixed by the Board of Directors of the Company
         and (5)  dividends or  distributions  referred to in  subparagraph  (i)
         above),  then in each case  (unless  the  Company  makes  the  election
         referred  to in the  next  sentence)  the  Conversion  Price  shall  be
         adjusted  so  that  the  same  shall  equal  the  price  determined  by
         multiplying  the Conversion  Price in effect  immediately  prior to the
         close of business on such record date by a fraction  the  numerator  of
         which  shall be the  Current  Market  Price  per share  (determined  as
         provided  in  subparagraph  (vii)  below) of the  Common  Stock on such
         record date (the  "REFERENCE  DATE") less the then fair market value on
         the  Reference  Date  (as  determined  in good  faith  by the  Board of
         Directors of the Company,  whose  determination shall be conclusive and
         shall be described  in a statement  filed with the  Depositary  and the
         Trustee) of the portion of the shares of capital  stock of the Company,
         evidences of indebtedness or other assets so

         distributed  (and for which an adjustment to the  Conversion  Price has
         not been made  previously  pursuant to the terms of this Article  Five)
         applicable  to one share of Common Stock and the  denominator  shall be
         such  Current  Market  Price  per  share  of  the  Common  Stock,  such
         adjustment  to become  effective  immediately  prior to the  opening of
         business on the day following the Reference Date. However,  the Company
         may elect, in its sole discretion, in lieu of the foregoing adjustment,
         to make adequate provision so that each holder of Securities shall have
         the right to receive  upon  conversion  thereof  the amount and kind of
         shares of capital stock, evidences of indebtedness or other assets such
         holder  would have  received had such holder  converted  such shares on
         such record date.  If the Board of Directors of the Company  determines
         the  fair  market  value  of any  distribution  for  purposes  of  this
         subparagraph  (iv) by  reference  to the actual or when issued  trading
         market  for any  securities  (including  shares  of  capital  stock  or
         evidence of indebtedness  of the Company)  comprising a distribution of
         securities,  it must in doing so consider the price in such market over
         the period used in  computing  the Current  Market  Price of the Common
         Stock.

                  For  purposes  of this  subparagraph  (iv),  any  dividend  or
         distribution  that  includes  both (x) any of the  items  described  in
         clauses  (A), (B) or (C) of the first  paragraph  of this  subparagraph
         (iv) and (y) Common  Stock or rights or  warrants to  subscribe  for or
         purchase  Common Stock of the type  referred to in  subparagraph  (iii)
         shall be  deemed  to be (1) a  dividend  or  distribution  of shares of
         capital stock of the Company  (other than Common  Stock),  evidences of
         indebtedness  of the Company or other assets of the type referred to in
         clause (C) of the first paragraph of this subparagraph (iv) (making any
         Conversion  Price  reduction   required  by  this  subparagraph   (iv))
         immediately  followed by (2) a dividend or  distribution of such Common
         Stock or  rights  or  warrants  to  purchase  Common  Stock of the type
         referred to in subparagraph  (iii) (making any further Conversion Price
         reduction  required  by  subparagraph  (i) or  (iii)  of  this  Section
         5.03(a)),   except  (A)  the   Reference   Date  of  such  dividend  or
         distribution as defined in this  subparagraph (iv) shall be substituted
         as "the date fixed for the  determination  of shareholders  entitled to
         receive  such  rights  or  warrants"  and  "the  date  fixed  for  such
         determination"  within the  meaning of  subparagraphs  (i) and (iii) of
         this  Section  5.03(a) and (B) any shares of Common  Stock  included in
         such dividend or distribution  shall not be deemed  "outstanding at the
         close of business on the date fixed for such determination"  within the
         meaning of subparagraph (i) of this Section 5.03(a).

                  The  occurrence  of a  distribution  or the  occurrence of any
         other  event as a result of which  holders of Series  5.50%  Debentures
         converting  such notes into Common Stock hereunder will not be entitled
         to receive rights issued pursuant to any shareholder  protective rights
         agreement  now or hereafter in effect (the "OTHER  RIGHTS") in the same
         amount  and  manner  as if  such  holders  had  converted  such  shares
         immediately prior to the occurrence of such distribution or other event
         shall be deemed a  distribution  of Other  Rights for the  purposes  of
         conversion  adjustments  pursuant to this subparagraph (iv). In lieu of
         making any adjustment to the Conversion  Price under this  subparagraph
         (iv) as a result of such a  distribution  of Other Rights,  the Company
         may elect, in its sole  discretion,  to provide that Other Rights shall
         be issuable in the same amount and manner upon conversion of the Series
         5.50%  Debentures  without regard to whether the shares of Common Stock
         issuable  upon  conversion of the Series 5.50%  Debentures  were issued
         before or after such distribution or other event.

              (v) In case the Company  shall,  by dividend or otherwise,  at any
         time distribute cash to all holders of Common Stock,  excluding (A) any
         cash  dividends on Common Stock to the extent that the  aggregate  cash
         dividends per share of Common Stock in any consecutive  12-month period
         do not exceed the  greater of (x) the amount per share of Common  Stock
         of the cash  dividends  paid on the  Common  Stock  in the  immediately
         preceding  12-month  period,  to the extent that such dividends for the
         immediately  preceding 12-month period did not require an adjustment to
         the Conversion Price pursuant to this  subparagraph (v) (as adjusted to
         reflect  subdivisions  or combinations of the Common Stock) and (y) 15%
         of the average of the daily Closing Prices (as hereinafter  defined) of
         the Common Stock for the ten consecutive Trading Days immediately prior
         to the date of  declaration  of such  dividend  and (B) any dividend or
         distribution  in  connection  with  the  liquidation,   dissolution  or
         winding-up of the Company,  whether  voluntary or  involuntary;  or any
         redemption of any Other Rights;  provided,  however, that no adjustment
         shall be made pursuant to this  subparagraph  (v) if such  distribution
         would  otherwise   constitute  a  Fundamental  Change  (as  hereinafter
         defined) and be reflected in a resulting  adjustment to the  Conversion
         Price as provided in this Article  Five) then, in each case (unless the
         Company makes the election  referred to in the proviso  following  this
         clause),  the Conversion  Price shall be reduced so that the same shall
         equal the price  determined  by  multiplying  the  Conversion  Price in
         effect at the close of business  on such record date by a fraction  the
         numerator  of which  shall be the  Closing  Price of a share of  Common
         Stock on such  record date less the amount of cash so  distributed  (to
         the extent not excluded as provided above) applicable to



                                       23
<PAGE>

         one share of Common  Stock,  and the  denominator  shall be the Closing
         Price of a share of Common Stock,  such  reduction to become  effective
         immediately  prior to the opening of business on the day following such
         record date; provided, however, that the Company may elect, in its sole
         discretion,  in  lieu of the  foregoing  adjustment,  to make  adequate
         provision so that each holder of Securities  shall  thereafter have the
         right to receive upon  conversion  the amount of cash such holder would
         have  received had such holder  converted  each Security on such record
         date.  If any  adjustment  is  required to be made as set forth in this
         subparagraph  (v) as a result  of a  distribution  which is a  dividend
         described in clause (A) of this  subparagraph (v), such adjustment will
         be based upon the amount by which such distribution  exceeds the amount
         of the dividend permitted to be excluded pursuant to such clause (A) of
         this subparagraph (v). If an adjustment is required to be made pursuant
         to this  subparagraph  (v) as a result of a  distribution  which is not
         such a dividend, such adjustment would be based upon the full amount of
         such distribution.

              (vi) In case of the  consummation  of a tender or  exchange  offer
         (other  than  an  odd-lot  tender  offer)  made by the  Company  or any
         subsidiary  of the Company  for all or any  portion of the  outstanding
         shares  of Common  Stock to the  extent  that the cash and fair  market
         value (as  determined  in good faith by the Board of  Directors  of the
         Company, whose determination shall be conclusive and shall be described
         in a resolution of such Board) of any other  consideration  included in
         such  payment  per  share  of  Common  Stock  at  the  last  time  (the
         "EXPIRATION  TIME")  tenders or exchanges  may be made pursuant to such
         tender or exchange offer (as amended) exceed by more than 10%, with any
         smaller  excess being  disregarded  in computing the  adjustment to the
         Conversion Price provided in this subparagraph (vi), the first reported
         sale price per share of Common Stock on the Trading Day next succeeding
         the Expiration Time, then the Conversion Price shall be reduced so that
         the same shall equal the price determined by multiplying the Conversion
         Price in effect  immediately prior to the Expiration Time by a fraction
         the  numerator  of which shall be the number of shares of Common  Stock
         outstanding  (including  any  tendered  or  exchanged  shares)  on  the
         Expiration  Time  multiplied  by the first  reported  sale price of the
         Common Stock on the Trading Day next succeeding the Expiration Time and
         the  denominator  shall  be the  sum  of  (x)  the  fair  market  value
         (determined  as aforesaid) of the  aggregate  consideration  payable to
         shareholders  based on the acceptance  (up to any maximum  specified in
         the  terms of the  tender or  exchange  offer)  of all  shares  validly
         tendered or exchanged and not withdrawn as of the Expiration  Time (the
         shares deemed so accepted, up to any such maximum, being referred to as
         the "PURCHASED SHARES") and (y) the



                                       24
<PAGE>

         product of the number of shares of Common Stock  outstanding  (less any
         Purchased  Shares) on the  Expiration  Time and the first reported sale
         price of the  Common  Stock on the  Trading  Day  next  succeeding  the
         Expiration Time, such reduction to become effective  immediately  prior
         to the opening of business on the day following the Expiration Time.

              (vii) For the purpose of any computation  under this Article Five,
         the  "CURRENT  MARKET PRICE PER SHARE" of Common Stock on any day shall
         be deemed to be the average of the daily Closing Prices (as hereinafter
         defined) per share of Common Stock for the ten consecutive Trading Days
         prior to and including the date in question;  provided,  however,  that
         (1) if the "ex" date (as hereinafter defined) for any event (other than
         the  issuance,   distribution  or  Fundamental  Change  requiring  such
         computation)  that  requires  an  adjustment  to the  Conversion  Price
         pursuant to this Article Five (the "OTHER  EVENT")  occurs  during such
         ten  consecutive  Trading  Days  and  prior  to the  "ex"  date for the
         issuance, distribution or Fundamental Change requiring such computation
         (the "CURRENT EVENT"),  the Closing Price for each Trading Day prior to
         the "ex" date for such Other Event  shall be  adjusted  by  multiplying
         such Closing Price by the same fraction by which the  Conversion  Price
         is so required to be adjusted as a result of such Other  Event,  (2) if
         the "ex" date for any Other Event  occurs on or after the "ex" date for
         the Current Event and on or prior to the date in question,  the Closing
         Price for each  Trading  Day on and after the "ex" date for such  Other
         Event  shall be  adjusted  by  multiplying  such  Closing  Price by the
         reciprocal of the fraction by which the Conversion Price is so required
         to be adjusted as a result of such Other  Event  (provided  that in the
         event  that  such  fraction  is  required  to be  determined  at a date
         subsequent to the date in question and with  reference to events taking
         place subsequent to the date in question, the Board of Directors of the
         Company  or,  to  the  extent  permitted  by  applicable  law,  a  duly
         authorized  committee thereof,  whose determination shall be conclusive
         and  described in a resolution of the Board of Directors of the Company
         or such duly authorized committee thereof, as the case may be, shall in
         good  faith  estimate  such  fraction  based  on  assumptions  it deems
         reasonable regarding such events taking place subsequent to the date in
         question,  and such  estimated  fraction  shall be used for purposes of
         such  adjustment  until such time as the actual  fraction  by which the
         Conversion  Price is so  required  to be  adjusted  as a result of such
         Other  Event is  determined),  and (3) if the "ex" date for the Current
         Event is on or prior to the date in question, after taking into account
         any adjustment  required pursuant to clause (1) or (2) of this proviso,
         the Closing Price for each Trading Day on or after such "ex" date shall
         be  adjusted  by  adding  thereto  the  amount of any cash and the fair
         market value (as determined in good



                                       25
<PAGE>

         faith by the  Board of  Directors  of the  Company  or,  to the  extent
         permitted by applicable law, a duly authorized  committee  thereof in a
         manner  consistent with any determination of such value for purposes of
         this  Article  Five,  whose   determination  shall  be  conclusive  and
         described in a  resolution  of the Board of Directors of the Company or
         such  duly  authorized  committee  thereof,  as the case may be) of the
         shares of capital  stock,  evidences  of  indebtedness  or other assets
         being  distributed  applicable  to one share of Common  Stock as of the
         close of  business on the day before  such "ex" date.  For  purposes of
         this subparagraph (vii), the term "ex" date, (1) when used with respect
         to any issuance,  distribution or Fundamental  Change,  means the first
         date on which the  Common  Stock  trades  regular  way on the  relevant
         exchange or in the  relevant  market  from which the Closing  Price was
         obtained without the right to receive such issuance,  such distribution
         or the cash, securities, property or other assets distributable in such
         Fundamental  Change to holders of the Common Stock,  (2) when used with
         respect to any  subdivision  or  combination of shares of Common Stock,
         means the first date on which the Common  Stock  trades  regular way on
         such  exchange  or  in  such  market  after  the  time  at  which  such
         subdivision  or  combination  becomes  effective and (3) when used with
         respect to any tender or  exchange  offer means the first date on which
         the Common Stock trades  regular way on such exchange or in such market
         after the Expiration Time of such offer.

              (viii) No  adjustment  in the  Conversion  Price shall be required
         pursuant to this Section 5.03(a) unless the adjustment  would require a
         change  of at  least  1% of such  price;  provided,  however,  that any
         adjustments  which  by  reason  of  this  subparagraph  (viii)  are not
         required to be made shall be carried  forward and taken into account in
         any  subsequent  adjustment.  All  calculations  shall  be  made to the
         nearest cent (with .005 being rounded upward) or to the nearest 1/100th
         of a share (with .005 of a share being rounded upward), as the case may
         be. Notwithstanding  anything to the contrary in this Article Five, the
         Company from time to time may, to the extent  permitted by law,  reduce
         the  Conversion  Price  by any  amount  for any  period  of at least 20
         Business  Days,  in which case the Company shall give at least 15 days'
         notice of such reduction to the holders of Series 5.50%  Debentures and
         the  Trustee.  In addition,  the Company may, at its option,  make such
         reductions  in the  Conversion  Price in addition to those set forth in
         this Article Five, as it considers to be advisable in order to avoid or
         diminish  any  income  tax to any  holders  of shares  of Common  Stock
         resulting  from any  dividend or  distribution  of stock or issuance of
         rights or warrants to purchase or subscribe for stock or from any event
         treated as such for income tax purposes or for any other reasons.



                                       26

              (ix) In any case in  which  this  Article  Five  provides  that an
         adjustment shall become effective  immediately  after a record date for
         an event,  the Company may defer until the occurrence of such event (A)
         issuing to the holder of any Series 5.50%  Debentures  converted  after
         such record date and before the occurrence of such event the additional
         shares of Common Stock  issuable upon such  conversion by reason of the
         adjustment  required  by such  event  over and above the  Common  Stock
         issuable upon such  conversion  before giving effect to such adjustment
         and  (B)  paying  to  such  holder  any  amount  in cash in lieu of any
         fractional shares pursuant to this Article Five.

              (x) For purposes of this Article Five, "COMMON STOCK" includes any
         stock of any class of the Company which has no preference in respect of
         dividends  or of  amounts  payable  in the  event of any  voluntary  or
         involuntary  liquidation,  dissolution or winding-up of the Company and
         which is not subject to redemption by the Company.  However, subject to
         the provisions of this Article Five,  shares  issuable on conversion of
         Series  5.50%  Debentures  shall  include  only  shares  of  the  class
         designated  as the  Company  Common  Stock on the  date of the  initial
         issuance  of Series  5.50%  Debentures  by the Company or shares of any
         class   or   classes   resulting   from   any    reclassification    or
         reclassification  thereof  and which have no  preference  in respect of
         dividends  or of  amounts  payable  in the  event of any  voluntary  or
         involuntary  liquidation,  dissolution or winding-up of the Company and
         which are not subject to redemption by the Company; provided,  however,
         that if at any time there shall be more than one such resulting  class,
         the shares of each such class then so issuable  shall be  substantially
         in the  proportion  which  the total  number  of  shares of such  class
         resulting from all such reclassifications  bears to the total number of
         shares of all such classes resulting from all such reclassifications.

         (b) Whenever the Conversion Price is adjusted as herein provided:

              (i) the Company  shall compute the adjusted  Conversion  Price and
         shall prepare a certificate  signed by the Chief  Financial  Officer or
         the  Treasurer of the Company  setting  forth the  adjusted  Conversion
         Price and  showing  in  reasonable  detail  the facts  upon  which such
         adjustment is based, and such certificate shall forthwith be filed with
         the Trustee and the transfer agent for the Preferred Securities and the
         Series 5.50% Debentures; and



                                       27
<PAGE>

              (ii) a notice stating the  Conversion  Price has been adjusted and
         setting  forth  the  adjusted   Conversion   Price  shall  as  soon  as
         practicable be mailed by the Company to all record holders of Preferred
         Securities  and the Series 5.50%  Debentures at their last addresses as
         they appear upon the stock transfer books of the Company and the Trust.

         SECTION 5.04. (a) In the event that the Company shall be a party to any
transaction  or  series  of  transactions  constituting  a  Fundamental  Change,
including,  without limitation,  (i) any recapitalization or reclassification of
shares of Common Stock (other than a change in the par value or as a result of a
subdivision or combination of the Common Stock),  (ii) any  consolidation of the
Company with, or merger of the Company into, any other corporation or any merger
of another  corporation  into the Company as a result of which holders of Common
Stock  shall be  entitled  to receive  securities  or other  property  or assets
(including  cash) with  respect to or in exchange for Common Stock (other than a
merger  which does not result in a  reclassification,  conversion,  exchange  or
cancellation of outstanding shares of Common Stock),  (iii) any sale or transfer
of all or substantially all of the assets of the Company, or (iv) any compulsory
share  exchange,  pursuant to any of which the holders of Common  Stock shall be
entitled to receive other securities,  cash or other property,  then appropriate
provision  shall be made as part of the terms of such  transaction  or series of
transactions so that the holder of each Series 5.50% Debenture then  outstanding
shall have the right thereafter to convert such Series 5.50% Debenture only into
(A) if any such  transaction  does not  constitute  a Common  Stock  Fundamental
Change (as hereinafter defined), the kind and amount of the securities,  cash or
other  property  that would  have been  receivable  upon such  recapitalization,
reclassification,  consolidation,  merger, sale, transfer or share exchange by a
holder of the number of shares of Common  Stock into  which  such  Series  5.50%
Debenture might have been converted immediately prior to such  recapitalization,
reclassification,  consolidation,  merger,  sale,  transfer  or share  exchange,
after, in the case of a Non-Stock  Fundamental Change (as hereinafter  defined),
giving  effect  to  any  adjustment  in the  Conversion  Price  required  by the
provisions which follow in subparagraph  (i) of Section 5.04(c),  and (B) if any
such transaction  constitutes a Common Stock Fundamental Change, common stock of
the kind  received by holders of Common  Stock as a result of such Common  Stock
Fundamental  Change in an amount  determined  pursuant to the  provisions  which
follow in  subparagraph  (ii) of Section  5.04(c).  The  company  formed by such
consolidation  or resulting  from such merger or which  acquires  such assets or
which  acquires  the  Common  Stock,  as the case  may be,  shall  enter  into a
supplemental  indenture with the Trustee,  satisfactory  in form to the Trustee,
the  provisions  of which  establishes  such right and provide  for  adjustments
which,  for  events  subsequent  to the  effective  date  of  such  supplemental
indenture,  shall  be  as  nearly  equivalent  as  may  be  practicable  to  the
adjustments provided for in this
Article Five.  The above



                                       28

provisions    shall    similarly    apply   to   successive    recapitalization,
reclassifications, consolidations, mergers, sales, transfers or share exchanges.

         (b)  Notwithstanding  any other  provisions in this Article Five to the
contrary,  if any Fundamental Change (as hereinafter  defined) occurs,  then the
Conversion  Price  in  effect  will  be  adjusted  immediately   following  such
Fundamental  Change as described below in Section 5.04(c).  In addition,  in the
event of a Common Stock Fundamental Change, each Series 5.50% Debenture shall be
convertible  solely into common stock of the kind  received by holders of Common
Stock as the result of such Common Stock Fundamental Change as more specifically
provided below in Section 5.04(c).

         (c) For purposes of  calculating  any adjustment to be made pursuant to
this Article Five in the event of a Fundamental  Change,  immediately  following
such  Fundamental  Change (and for such purposes a  Fundamental  Change shall be
deemed to occur on the earlier of (a) the occurrence of such Fundamental  Change
and (b) the date, if any, fixed for  determination  of shareholders  entitled to
receive the cash,  securities,  property or other assets  distributable  in such
Fundamental Change to holders of the Common Stock):

              (i) in the case of a Non-Stock  Fundamental Change, the Conversion
         Price per share of Common Stock  immediately  following  such Non-Stock
         Fundamental  Change shall be the lower of (A) the  Conversion  Price in
         effect  immediately  prior to such Non-Stock  Fundamental  Change,  but
         after giving effect to any other adjustments  effected pursuant to this
         Article Five,  and (B) the product of (1) the greater of the Applicable
         Price (as hereinafter  defined) or the then applicable Reference Market
         Price (as  hereinafter  defined)  and (2) a fraction  the  numerator of
         which  shall be $100 and the  denominator  of which shall be the amount
         based on the date on which such  Non-Stock  Fundamental  Change occurs.
         For the twelve month period beginning October 29, 1997, the denominator
         will be 105.50, and the denominator will decrease by 0.6875 during each
         successive 12-month period;  provided, that the denominator shall in no
         event be less than 100.0.

              (ii)  in the  case  of a  Common  Stock  Fundamental  Change,  the
         Conversion  Price per share of Common Stock  immediately  following the
         Common Stock Fundamental Change shall be the Conversion Price in effect
         immediately  prior to such Common Stock Fundamental  Change,  but after
         giving  effect  to any  other  adjustments  effected  pursuant  to this
         Article Five,  multiplied by a fraction,  the numerator of which is the
         Purchaser Stock Price (as  hereinafter  defined) and the denominator of
         which is the Applicable Price; provided,  however, that in the event of
         a



                                       29
<PAGE>

         Common Stock Fundamental Change in which (A) 100% of the value  of  the
         consideration  received by a holder of Common  Stock is common stock of
         the  successor,  acquiror or other third party (and cash,  if any, paid
         with respect to any fractional interests in such common stock resulting
         from such Common  Stock  Fundamental  Change) and (B) all of the Common
         Stock shall have been  exchanged  for,  converted  into or acquired for
         common stock (and cash, if any,  with respect to fractional  interests)
         of the successor,  acquiror or other third party,  the Conversion Price
         per share of Common  Stock  immediately  following  such  Common  Stock
         Fundamental  Change shall be the Conversion Price in effect immediately
         prior to such Common Stock Fundamental  Change divided by the number of
         shares of common stock of the successor, acquiror, or other third party
         received  by a holder of one share of Common  Stock as a result of such
         Common Stock Fundamental Change.

         (d)  The  following  definitions  shall  apply  to  terms  used in this
Article Five:

              (i) "APPLICABLE PRICE" shall mean (A) in the event of a Non- Stock
         Fundamental  Change in which the holders of Common  Stock  receive only
         cash, the amount of cash  receivable by a holder of one share of Common
         Stock and (B) in the event of any other Fundamental Change, the average
         of the  Closing  Prices  for one share of Common  Stock  during the ten
         Trading Days immediately prior to the record date for the determination
         of the holders of Common Stock  entitled to receive  cash,  securities,
         property or other assets in connection with such Fundamental Change or,
         if there is no such  record  date,  prior to the date  upon  which  the
         holders of Common  Stock  shall  have the right to  receive  such cash,
         securities, property or other assets.

              (ii)  "CLOSING  PRICE" with respect to any  securities  on any day
         shall mean the closing sale price, regular way, on such day or, in case
         no such sale  takes  place on such day,  the  average  of the  reported
         closing bid and asked prices, regular way, in each case on the New York
         Stock  Exchange  or, if such  security  is not  listed or  admitted  to
         trading on such Exchange, on the principal national securities exchange
         or  quotation  system  on which  such  security  is quoted or listed or
         admitted  to trading or, if not quoted or listed or admitted to trading
         on any national securities exchange or quotation system, the average of
         the   closing   bid  and  asked   prices  of  such   security   on  the
         over-the-counter  market on the date in  question  as  reported  by the
         National  Quotation  Bureau  Incorporated,  or  a  similarly  generally
         accepted  reporting service or, if not so available,  in such manner as
         furnished by any New York Stock Exchange member firm



                                       30

         selected from time to time by the Board of Directors of the Company for
         that  purpose  or a price  determined  in good  faith  by the  Board of
         Directors of the Company.

              (iii) "COMMON STOCK FUNDAMENTAL CHANGE" shall mean any Fundamental
         Change in which more than 50% of the value (as determined in good faith
         by the Board of Directors of the Company) of the consideration received
         by the holders of Common Stock pursuant to such  transactions  consists
         of shares of common stock that,  for the ten  consecutive  Trading Days
         immediately  prior to such  Fundamental  Change,  has been admitted for
         listing or  admitted  for  listing  subject to notice of  issuance on a
         national  securities  exchange or quoted on the Nasdaq National Market;
         provided,  however,  that a  Fundamental  Change  shall not be a Common
         Stock  Fundamental  Change unless  either (A) the Company  continues to
         exist  after  the  occurrence  of  such  Fundamental   Change  and  the
         outstanding  Preferred  Securities  continue  to exist  as  outstanding
         Preferred  Securities,  or (B)  the  outstanding  Preferred  Securities
         continue to exist as  Preferred  Securities  and are  convertible  into
         common stock of the successor to the Company.

              (iv)  "FUNDAMENTAL  CHANGE"  shall  mean  the  occurrence  of  any
         transaction or event or series of  transactions  or events  pursuant to

         receive cash, securities, property or other assets (whether by means of
         an exchange offer, liquidation,  tender offer,  consolidation,  merger,
         combination,   reclassification,    recapitalization   or   otherwise);
         provided,  however,  in the case of a plan involving more than one such
         transaction  or event,  for purposes of  adjustment  of the  Conversion
         Price,  such  Fundamental  Change shall be deemed to have occurred when
         substantially all of the Common Stock has been exchanged for, converted
         into, or acquired for or constitutes  solely the right to receive cash,
         securities, property or other assets, but the adjustment shall be based
         upon the  consideration  which the holders of Common Stock  received in
         such  transaction  or event as a result  of which  more than 50% of the
         Common Stock shall have been exchanged for, converted into, or acquired
         for or shall constitute  solely the right to receive cash,  securities,
         property or other assets.

              (v)  "NON-STOCK  FUNDAMENTAL  CHANGE"  shall mean any  Fundamental
         Change other than a Common Stock Fundamental Change.

              (vi)  "PURCHASER  STOCK  PRICE"  shall mean,  with  respect to any
         Common Stock Fundamental  Change, the average of the Closing Prices

         for one share of the common  stock  received by holders of Common Stock
         in such Common  Stock  Fundamental  Change  during the ten Trading Days
         immediately  prior  to the  record  date for the  determination  of the
         holders of Common  Stock  entitled to receive  such common stock or, if
         there is no such record date,  prior to the date upon which the holders
         of Common Stock shall have the right to receive such common stock.

              (vii) "REFERENCE  MARKET PRICE" shall initially mean $29.92 (which
         is an amount equal to 66-2/3% of the last  reported  sale price for the
         Common  Stock on the New York Stock  Exchange on October 23, 1997) and,
         in the event of any adjustment to the Conversion  Price other than as a
         result of a Fundamental  Change,  the Reference Market Price shall also
         be  adjusted  so that the ratio of the  Reference  Market  Price to the
         Conversion  Price  after  giving  effect to any such  adjustment  shall
         always be the same as the ratio of the initial  Reference  Market Price
         to the initial Conversion Price set forth in this Article Five.

         (e) In determining the amount and type of  consideration  received by a
holder  of  Common  Stock in the event of a  Fundamental  Change,  consideration
received by a holder of Common Stock pursuant to a statutory  right of appraisal
will be disregarded.

         SECTION 5.05.    In case:

              (i)  the  Company   shall   declare  a  dividend   (or  any  other
         distribution)  on Common  Stock that would cause an  adjustment  to the
         Conversion Price of the Series 5.50%  Debentures  pursuant to the terms
         of any of the  subparagraphs  above  (including such an adjustment that
         would  occur  but  for the  terms  of the  first  sentence  of  Section
         5.03(a)(viii) above); or

              (ii) the  outstanding  shares of Common Stock shall be  subdivided
         into a greater  number of shares  of Common  Stock or  combined  into a
         smaller number of shares of Common Stock; or

              (iii) the Company  shall  authorize the granting to the holders of
         Common  Stock  generally of rights or warrants  (for a period  expiring
         within 45 days after the record date fixed for a  distribution  of such
         rights and  warrants)  to  subscribe  for or purchase any shares of the
         Company's  capital  stock or other capital stock of any class or of any
         other rights (including any Rights Offerings); or



                                       32
<PAGE>

              (iv)  of  any  reclassification  of  Common  Stock  (other  than a
         subdivision or combination of the outstanding  shares of Common Stock),
         or of any consolidation,  merger or share exchange to which the Company
         is a party and for which approval of any shareholders of the Company is
         required, or of the sale or transfer of all or substantially all of the
         assets of the Company or a compulsory share exchange; or

              (v) of the voluntary or  involuntary  dissolution,  liquidation or
         winding-up of the Company;

         then the Company shall (i) if any Preferred Securities are outstanding,
cause to be filed with the  transfer  agent for the  Preferred  Securities,  and
shall cause to be mailed to the holders of record of the  Preferred  Securities,
at their last  addresses as they shall appear upon the stock  transfer  books of
the  Trust or (ii)  shall  cause  to be  mailed  to all  Holders  at their  last
addresses as they shall  appear in the books and records of the Trust,  at least
15 days prior to the applicable record or effective date hereinafter  specified,
a notice  stating (A) the date on which a record (if any) is to be taken for the
purpose of such  dividend,  distribution,  rights or warrants or, if a record is
not to be taken,  the date as of which the holders of Common  Stock of record to
be  entitled  to such  dividend,  distribution,  rights  or  warrants  are to be
determined  or (B)  the  date on  which  such  reclassification,  consolidation,
merger, sale, transfer, share exchange,  dissolution,  liquidation or winding up
is expected to become  effective,  and the date as of which it is expected  that
holders of Common Stock of record shall be entitled to exchange  their shares of
Common  Stock  for  securities,  cash or other  property  deliverable  upon such
reclassification,   consolidation,   merger,  sale,  transfer,  share  exchange,
dissolution,  liquidation  or winding up (but no failure to mail such  notice or
any defect  therein or in the mailing  thereof  shall affect the validity of the
corporate action required to be specified in such notice).

         SECTION 5.06. The Company shall reserve,  free from pre-emptive rights,
out of its authorized but unissued shares,  sufficient shares to provide for the
conversion of the Series 5.50% Debentures from time to time as such Series 5.50%
Debentures are presented for conversion, provided, that nothing contained herein
shall be construed to preclude the Company from  satisfying  its  obligations in
respect of the conversion of Series 5.50%  Debentures by delivery of repurchased
shares of Common Stock which are held in the treasury of the Company.

         If any  shares  of  Common  Stock to be  reserved  for the  purpose  of
conversion of Series 5.50% Debentures  hereunder  require  registration  with or
approval of any governmental authority under any Federal or State law before
such shares may be validly issued or delivered upon conversion, then the



                                       33
<PAGE>

Company  covenants that it will in good faith and as  expeditiously  as possible
endeavor to secure such registration or approval,  as the case may be, provided,
however,  that nothing in this Section 5.06 shall be deemed to affect in any way
the  obligations of the Company to convert Series 5.50%  Debentures  into Common
Stock as provided in this Article Five.

         Before taking any action which would cause an  adjustment  reducing the
Conversion  Price  below the then par value,  if any, of the Common  Stock,  the
Company will take all corporate action which may, in the Opinion of Counsel,  be
necessary in order that the Company may validly and legally issue fully paid and
non-assessable shares of Common Stock at such adjusted Conversion Price.

         The  Company  covenants  that all shares of Common  Stock  which may be
issued upon conversion of Series 5.50%  Debentures will upon issue be fully paid
and non-assessable by the Company and free of pre-emptive rights.

         SECTION 5.07. Notwithstanding the foregoing provisions, the issuance of
any shares of Common Stock pursuant to any plan  providing for the  reinvestment
of dividends or interest payable on securities of the Company and the investment
of  additional  optional  amounts in shares of Common Stock under any such plan,
and the  issuance of any shares of Common Stock or options or rights to purchase
such shares  pursuant to any employee  benefit plan or program of the Company or
pursuant  to  any  option,  warrant,  right  or  exercisable,   exchangeable  or
convertible  security outstanding as of October 29, 1997, shall not be deemed to
constitute  an  issuance  of  Common  Stock  or  exercisable,   exchangeable  or
convertible  securities by the Company to which any of the adjustment provisions
described  above  applies.  There shall also be no adjustment of the  Conversion
Price in case of the issuance of any stock (or  securities  convertible  into or
exchangeable for stock) of the Company except as specifically  described in this
Article Five.

         SECTION  5.08.  In case the Company  shall,  by dividend or  otherwise,
declare  or make a  distribution  on the  Common  Stock  referred  to in Section
5.03(a)(iv)  or  5.03(a)(v)   (including,   without  limitation,   dividends  or
distributions  referred  to in the last  sentence of Section  5.03(a)(vi)),  the
Holder of the Series 5.50% Debenture,  upon the conversion thereof subsequent to
the close of business on the date fixed for the  determination  of  stockholders
entitled to receive  such  distribution  and prior to the  effectiveness  of the
Conversion  Price  adjustment  in  respect of such  distribution,  shall also be
entitled to receive for each share of Common  Stock into which the Series  5.50%
Debentures  are  converted,  the portion of the shares of Common Stock,  rights,
warrants, evidences of indebtedness, shares of capital stock, cash and assets so
distributed applicable to one share of Common Stock; provided, however, that, at
the election of the Company  (whose  election shall be evidenced by a resolution
of the Board of



                                       34
<PAGE>

Directors)  with respect to all Holders so converting,  the Company may, in lieu
of distributing to such Holder any portion of such  distribution  not consisting
of cash or securities of the Company, pay such Holder an amount in cash equal to
the fair  market  value  thereof  (as  determined  in good faith by the Board of
Directors, whose determination shall be conclusive and described in a resolution
of the  Board of  Directors).  If any  conversion  of  Series  5.50%  Debentures
described in the immediately preceding sentence occurs prior to the payment date
for a  distribution  to holders of Common Stock which the Holder of Series 5.50%
Debentures  so  converted  is  entitled  to  receive  in  accordance   with  the
immediately  preceding  sentence,  the Company  may elect  (such  election to be
evidenced by a  resolution  of the Board of  Directors)  to  distribute  to such
Holder a due bill for the shares of Common Stock, rights, warrants, evidences of
indebtedness, shares of capital stock, cash or assets to which such Holder is so
entitled,  provided, that such due bill (a) meets any applicable requirements of
the principal national  securities  exchange or other market on which the Common
Stock is then  traded and (b)  requires  payment or  delivery  of such shares of
Common Stock,  rights,  warrants,  evidences of indebtedness,  shares of capital
stock,  cash or assets no later than the date of payment or delivery  thereof to
holders of shares of Common Stock receiving such distribution.

computed on the basis of a 360-day year twelve 30-day months.  In the event that
any date on which  interest is payable on this  Debenture is not a business day,
then  payment  of  interest  payable  on such  date  will  be  made on the  next
succeeding  day which is a  business  day (and  without  any  interest  or other
payment in respect of any such delay),  except that,  if such business day is in
the next succeeding calendar year,



                                       36
<PAGE>

such payment shall be made on the  immediately  preceding  business day, in each
case  with the same  force  and  effect as if made on such  date.  The  interest
installment  so  payable,  and  punctually  paid or duly  provided  for,  on any
Interest Payment Date will, as provided in the Indenture,  be paid to the person
in whose name this Debenture (or one or more Predecessor Debentures,  as defined
in said  Indenture) is registered at the close of business on the regular record
date for such interest installment, [which shall be the close of business on the
day next  preceding  such  Interest  Payment  Date,  provided  if the  Preferred
Securities  of AES Trust II are no longer in book-entry  only form,  the regular
record dates shall be the close of business on the  fifteenth  (15th) day of the
month in which such Interest Payment Date occurs] [IF PURSUANT TO THE PROVISIONS
OF SECTION  2.11(c) OF THE INDENTURE OR SECTION 1.04 OF THE SECOND  SUPPLEMENTAL
INDENTURE THE SERIES 5.50%  DEBENTURES ARE NOT REPRESENTED BY A GLOBAL DEBENTURE
- -- which shall be the close of business on the fifteenth (15th) day of the month
in which such Interest  Payment Date occurs.] Any such interest  installment not
punctually  paid or duly provided for shall forthwith cease to be payable to the
registered holders on such regular record date, and may be paid to the person in
whose name this Debenture (or one or more Predecessor  Debentures) is registered
at the close of business on a special record date to be fixed by the Trustee for
the payment of such  defaulted  interest,  notice  whereof shall be given to the
registered  holders of this series of Debentures  not less than 10 days prior to
such special  record date, or may be paid at any time in any other lawful manner
not inconsistent  with the requirements of any securities  exchange on which the
Debentures  may be  listed,  and upon  such  notice as may be  required  by such
exchange,  all as more fully  provided in the  Indenture.  The principal of (and
premium,  if any) and the  interest  on this  Debenture  shall be payable at the
office or agency of the Company  maintained  for that  purpose in the Borough of
Manhattan, The City and State of New York, in any coin or currency of the United
States of America  which at the time of payment is legal  tender for  payment of
public and private  debts;  provided,  however,  that payment of interest may be
made at the option of the Company by check  mailed to the  registered  holder at
such address as shall appear in the  Debenture  register and that the payment of
principal will only be made upon the surrender of this Debenture to the Trustee.
Notwithstanding  the  foregoing,  so long as the owner and record holder of this
Debenture is the Property  Trustee (as defined in the  Indenture  referred to on
the reverse hereof),  the payment of the principal of (and premium,  if any) and
interest (including  Compounded Interest, if any) on this Debenture will be made
at such place and to such account of the Property  Trustee as may be  designated
by the Property Trustee.

         The indebtedness evidenced by this Debenture is, to the extent provided
in the  Indenture,  subordinate  and  subject  in right of  payment to the prior
payment in full of all Senior  and  Subordinated  Debt,  and this  Debenture  is
issued subject to



                                       37
<PAGE>

the  provisions  of the  Indenture  with  respect  thereto.  Each Holder of this
Debenture,  by  accepting  the  same,  (a)  agrees to and shall be bound by such
provisions,  (b)  authorizes  and directs the Trustee on his behalf to take such
action as may be necessary or  appropriate  to  acknowledge  or  effectuate  the
subordination so provided and (c) appoints the Trustee his  attorney-in-fact for
any and all such purposes.  Each Holder hereof, by his acceptance hereof, hereby
waives all notice of the acceptance of the  subordination  provisions  contained
herein and in the  Indenture  by each  holder of Senior and  Subordinated  Debt,
whether now outstanding or hereafter incurred,  and waives reliance by each such
Holder upon said provisions.

         This Debenture shall not be entitled to any benefit under the Indenture
hereinafter referred to, be valid or become obligatory for any purpose until the
Certificate of  Authentication  hereon shall have been signed by or on behalf of
the Trustee.

         The  provisions  of this  Debenture  are  continued on the reverse side
hereof and such continued provisions shall for all purposes have the same effect
as though fully set forth at this place.

         IN WITNESS  WHEREOF,  the  Company  has caused  this  Instrument  to be
executed.

                         (FORM OF REVERSE OF DEBENTURE)


         This Debenture is one of a duly authorized  series of Debentures of the
Company (herein  sometimes  referred to as the  "DEBENTURES"),  specified in the
Indenture,  all issued or to be issued in one or more series  under and pursuant
to an Indenture  dated as of March 1, 1997 duly executed and  delivered  between
the  Company  and  The  First  National  Bank of  Chicago,  a  national  banking
association,  as Trustee (herein referred to as the "TRUSTEE"),  as supplemented
by the Second  Supplemental  Indenture  dated as of October 29, 1997 between the
Company and the Trustee (said  Indenture as so  supplemented  being  hereinafter
referred  to  as  the  "INDENTURE"),  to  which  Indenture  and  all  indentures
supplemental  thereto  reference is hereby made for a description of the rights,
limitations  of rights,  obligations,  duties and  immunities  thereunder of the
Trustee,  the  Company  and the  holders of the  Debentures,  and, to the extent
specifically set forth in the Indenture,  the holders of Senior and Subordinated
Debt and Preferred Securities. By the terms of the Indenture, the Debentures are
issuable  in  series  which may vary as to  amount,  date of  maturity,  rate of
interest  and in other  respects as in the  Indenture  provided.  This series of
Debentures is designated the 5.50% Junior  Subordinated  Debentures due 2012 and
is  limited  in  aggregate   principal   amount  as  specified  in  said  Second
Supplemental Indenture.

         Except as provided in the next  paragraph,  the  Debentures  may not be
redeemed by the Company prior to September 30, 2000.  The Company shall have the
right to redeem this Debenture at the option of the Company,  without premium or
penalty,  in whole or in part at any time on or  after  September  30,  2000 (an
"OPTIONAL  REDEMPTION"),  upon not less than 30 nor move than 60 days  notice to
the Holder of the Series 5.50% Debentures, at the following prices (as expressed
as  percentages  of the  principal  amount  of the  Debentures)  (the  "OPTIONAL
REDEMPTION PRICE"), together with any accrued but unpaid interest, including any
Compounded Interest, if any, to, but including, the date of such redemption,  if
redeemed during the 12-month period beginning September 30:


                       YEAR                  REDEMPTION PRICE
                       ----                  ----------------
                       2000                      103.438%
                       2001                      102.750%
                       2002                      102.063%
                       2003                      101.375%
                       2004                      100.688%

and 100% if redeemed on or after September 30, 2005.



                                       40
<PAGE>

         If the Series 5.50%  Debentures  are  redeemed on any Interest  Payment
Date,  accrued and unpaid  interest shall be payable to Holders of record on the
relevant record date.

         The  Company  may not  redeem any Series  5.50%  Debentures  unless all
accrued and unpaid interest thereon,  including Compounded Interest, if any, has
been  paid  for all  quarterly  periods  terminating  on or prior to the date of
notice of  redemption.  So long as the  corresponding  Preferred  Securities are
outstanding,  the proceeds from the  redemption  of the Series 5.50%  Debentures
will be used to redeem the Preferred Securities.

         If the Debentures are only partially  redeemed by the Company  pursuant
to an Optional Redemption, the Debentures will be redeemed pro rata or by lot or
by any  other  method  utilized  by the  Trustee;  provided  if,  at the time of
redemption,  the Debentures are registered as a Global Debenture, the Depository
shall  determine the principal  amount of such Debentures held by each holder of
Debentures to be redeemed in accordance with its customary procedures.

         If, at any  time,  a Tax Event (as  defined  below)  shall  occur or be
continuing after receipt of a Dissolution Tax Opinion (as defined below) and (i)
the  Regular  Trustees  and the  Company  shall  have  received  an  opinion  (a
"REDEMPTION  TAX OPINION") of a nationally  recognized  independent  tax counsel
experienced in such matters that, as a result of a Tax Event, there is more than
an  insubstantial  risk that the Company would be precluded  from  deducting the
interest on the Debentures for United States federal income tax purposes even if
the  Debentures  were  distributed  to the holders of Preferred  Securities  and
Common  Securities in liquidation  of such holder's  interest in AES Trust II as
set forth in the  Declaration  of Trust or (ii) the Regular  Trustees shall have
been  informed by such tax  counsel  that a No  Recognition  Opinion (as defined
below)  cannot be delivered to AES Trust II, the Company shall have the right at
any time,  upon not less than 30 nor more than 60 days'  notice,  to redeem  the
Debentures  in  whole  or in  part  for  cash at a  price  equal  to 100% of the
principal amount thereof, together with any accrued and unpaid interest thereon,
including  Compounded Interest if any, to, but excluding the date of redemption,
within 90 days  following the occurrence of such Tax Event;  provided,  however,
that,  if at the time there is available to the Company or the Regular  Trustees
on behalf of AES  Trust II the  opportunity  to  eliminate,  within  such 90 day
period, the Tax Event by taking some ministerial action ("MINISTERIAL  ACTION"),
such as filing a form or making an  election,  or  pursuing  some other  similar
reasonable measure,  which has no adverse effect on AES Trust II, the Company or
the holders of the Preferred Securities,  the Company or the Regular Trustees on
behalf  of AES Trust II will  pursue  such  measure  in lieu of  redemption  and
provided further that the Company shall have



                                       41
<PAGE>

no right to redeem the  Debentures  while the Regular  Trustees on behalf of AES
Trust II are pursuing any such Ministerial Action.

         "TAX EVENT" means that the Company and the Regular  Trustees shall have
obtained an opinion of nationally recognized independent tax counsel experienced
in such  matters (a  "DISSOLUTION  TAX  OPINION") to the effect that on or after
October 23, 1997,  as a result of (a) any  amendment  to, or change in, the laws
(or  any  regulations   thereunder)  of  the  United  States  or  any  political
subdivision  or taxing  authority  thereof or therein,  (b) any amendment to, or
change in, an  interpretation  or application of any such laws or regulations by
any  legislative  body,  court,  governmental  agency  or  regulatory  authority
(including the enactment of any  legislation and the publication of any judicial
decision or regulatory  determination),  (c) any interpretation or pronouncement
that  provides  for a position  with  respect to such laws or  regulations  that
differs from the theretofore generally accepted position or (d) any action taken
by any governmental agency or regulatory authority, which amendment or change is
enacted,   promulgated,   issued  or  effective  or  which   interpretation   or
pronouncement  is issued or announced or which action is taken,  in each case on
or after October 23, 1997, there is more than an insubstantial risk that (i) AES
Trust II is, or will be within 90 days of the date  thereof,  subject  to United
States  federal  income tax with  respect to income  accrued or  received on the
Debentures, (ii) AES Trust II is, or will be within 90 days of the date thereof,
subject to more than a de minimis amount of taxes,  duties or other governmental
charges  or  (iii)  interest  payable  by the  Company  to AES  Trust  II on the
Debentures is not, or within 90 days of the date thereof will not be, deductible
by the Company for United States federal income tax purposes.

         "NO  RECOGNITION  OPINION" means an opinion of a nationally  recognized
independent tax counsel  experienced in such matters,  which opinion may rely on
any then applicable published revenue ruling of the Internal Revenue Service, to
the effect that the holders of the Preferred  Securities  will not recognize any
gain or loss for United  States  federal  income tax  purposes  as a result of a
dissolution  of AES Trust II and  distribution  of the Debentures as provided in
the Declaration of Trust.

         If the Debentures are only partially  redeemed by the Company  pursuant
to an Optional  Redemption or as a result of a Tax Event as described above, the
Debentures will be redeemed pro rata or by lot or in some other equitable manner
determined  by  the  Trustee.   Notwithstanding  the  foregoing,  if  a  partial
redemption  of the  Debentures  would result in the  delisting of the  Preferred
Securities by any national  securities  exchange or other  organization on which
the Preferred  Securities are then listed, the Company shall not be permitted to
effect such partial redemption and will only redeem the Debentures in whole.



                                       42
<PAGE>

         In the  event of  redemption  of this  Debenture  in part  only,  a new
Debenture or Debentures  of this series for  unredeemed  portion  hereof will be
issued in the name of the Holder hereof upon the cancellation hereof.

         In case an Event of Default,  as defined in the  Indenture,  shall have
occurred  and be  continuing,  the  principal  of all of the  Debentures  may be
declared,  and upon such  declaration  shall  become,  due and  payable,  in the
manner, with the effect and subject to the conditions provided in the Indenture.

         The Indenture  contains  provisions  for  defeasance at any time of the
entire  indebtedness  of this  Debenture  upon  compliance  by the Company  with
certain conditions set forth therein.

         The  Indenture  contains  provisions  permitting  the  Company  and the
Trustee,  with the  consent  of the  Holders  of not  less  than a  majority  in
aggregate principal amount of the Debentures of each series affected at the time
outstanding,  as defined  in the  Indenture  (and,  in the case of any series of
Debentures  held as trust  assets of an AES Trust  and with  respect  to which a
Security Exchange has not theretofore  occurred,  such consent of holders of the
Preferred  Securities  and the  Common  Securities  of such AES Trust) as may be
required  under  the   Declaration  of  Trust  of  such  AES  Trust  to  execute
supplemental  indentures for the purpose of adding any provisions to or changing
in any manner or  eliminating  any of the  provisions of the Indenture or of any
supplemental  indenture  or of modifying in any manner the rights of the Holders
of the Debentures;  provided, however, that no such supplemental indenture shall
(i) extend the fixed  maturity of any  Debentures  of any series,  or reduce the
principal  amount  thereof,  or reduce the rate or extend the time of payment of
interest  thereon,  or reduce any premium  payable upon the redemption  thereof,
without the consent of the holder of each  Debenture  so affected or (ii) reduce
the  aforesaid  percentage of  Debentures,  the holders of which are required to
consent to any such supplemental  indenture,  without the consent of the holders
of each  Debenture  (and, in the case of any series of Debentures  held as trust
assets of an AES Trust and with  respect  to which a Security  Exchange  has not
theretofore  occurred,  such consent of the holders of the Preferred  Securities
and the  Common  Securities  of such AES  Trust  as may be  required  under  the
Declaration of Trust of such AES Trust) then  outstanding and affected  thereby.
The Indenture also contains  provisions  permitting the Holders of a majority in
aggregate principal amount of the Debentures of a series at the time outstanding
affected thereby (subject, in the case of any series of Debentures held as trust
assets of an AES Trust and with respect to which a  Securities  Exchange has not
theretofore  occurred,  to such consent of holders of Preferred  Securities  and
Common  Securities of such AES Trust as may be required under the Declaration of
Trust of such AES  Trust),  on behalf of the Holders of the  Debentures  of such
series, to waive any past default in the



                                       43
<PAGE>

performance of any of the covenants  contained in the Indenture,  or established
pursuant to the  Indenture  with respect to such series,  and its  consequences,
except a default in the  payment of the  principal  of or  premium,  if any,  or
interest on any of the Debentures of such series.  Any such consent or waiver by
the  registered  Holder of this  Debenture  (unless  revoked as  provided in the
Indenture)  shall be conclusive and binding upon such Holder and upon all future
Holders and owners of this  Debenture  and of any  Debenture  issued in exchange
herefor or in place hereof  (whether by  registration of transfer or otherwise),
irrespective  of whether or not any  notation of such  consent or waiver is made
upon this Debenture.

         Subject to Section 13.12 of the Indenture,  no reference  herein to the
Indenture (other than such Section) and no provision of this Debenture or of the
Indenture shall alter or impair the obligation of the Company, which is absolute
and unconditional,  to pay the principal of and premium, if any, and interest on
this  Debenture  at the time and  place  at the  rate  and in the  money  herein
prescribed.

         So long as the  Company is not in default in the payment of interest on
the Debentures, the Company shall have the right, at any time during the term of
the Debentures,  from time to time to extend the interest payment period of such
Debentures for up to 20 consecutive  quarterly  interest  periods (the "EXTENDED
INTEREST PAYMENT PERIOD"),  at the end of which period the Company shall pay all
interest then accrued and unpaid  (together with interest thereon at the rate of
5.50% per annum to the extent permitted by applicable law, compounded  quarterly
("COMPOUNDED INTEREST"));  provided that no Extended Interest Payment Period may
extend  beyond the date of maturity or any  redemption  date of the  Debentures.
During such Extended  Interest  Payment  Period the Company shall not declare or
pay any  dividend on, or redeem,  purchase,  acquire or make a  distribution  or
liquidation payment with respect to, any of its common stock or preferred stock,
or make any guarantee payments with respect thereto, provided that the foregoing
will not apply to any stock  dividends,  paid by the  Company  in Common  Stock.
Prior to the  termination  of any such Extended  Interest  Payment  Period,  the
Company may pay all or any portion of the interest  accrued on the Debentures on
any Interest  Payment  Date to holders of record on the regular  record date for
such  Interest  Payment Date or from time to time further  extend such  Extended
Interest  Payment  Period,  provided  that such  Period  together  with all such
further  extensions  thereof shall not exceed 20 consecutive  quarterly interest
periods.  At the  termination of any such Extended  Interest  Payment Period and
upon the payment of all  accrued and unpaid  interest  then due,  together  with
Compounded  Interest,  the Company may select a new  Extended  Interest  Payment
Period,  subject to the foregoing  requirements.  No interest on this  Debenture
shall be due and payable during an Extended  Interest Payment Period,  except at
the end thereof.  At the end of the Extended Interest Payment Period the Company
shall pay all  interest  accrued  and  unpaid on the  Debentures  including  any
Compounded



                                       44
<PAGE>

Interest  which shall be payable to the holders of the Debentures in whose names
the Debentures are registered in the Debenture register on the first record date
after the end of the Extended Interest Payment Period.

         As provided in the Indenture and subject to certain limitations therein
set forth, this Debenture is transferable by the registered holder hereof on the
Debenture  register  of the  Company,  upon  surrender  of  this  Debenture  for
registration  of  transfer at the office or agency of the Company in the Borough
of Manhattan, The City and State of New York accompanied by a written instrument
or  instruments of transfer in form  satisfactory  to the Company or the Trustee
duly executed by the registered holder hereof or his attorney duly authorized in
writing,  and thereupon one or more new  Debentures of authorized  denominations
and for the same  aggregate  principal  amount and series  will be issued to the
designated  transferee or  transferees.  No service  charge will be made for any
such transfer,  but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in relation thereto.

         Prior  to  due  presentment  for   registration  of  transfer  of  this
Debenture,  the  Company,  the  Trustee,  any  paying  agent  and any  Debenture
Registrar may deem and treat the registered  holder hereof as the absolute owner
hereof (whether or not this Debenture shall be overdue and  notwithstanding  any
notice of  ownership or writing  hereon made by anyone other than the  Debenture
Registrar)  for  the  purpose  of  receiving  payment  of or on  account  of the
principal hereof and premium,  if any, and interest due hereon and for all other
purposes,  and neither the Company nor the Trustee nor any paying  agent nor any
Debenture Registrar shall be affected by any notice to the contrary.

         No  recourse  shall be had for the payment of the  principal  of or the
interest on this  Debenture,  or for any claim based  hereon,  or  otherwise  in
respect  hereof,  or  based  on or in  respect  of the  Indenture,  against  any
incorporator,  stockholder,  officer or director,  past,  present or future,  as
such, of the Company or of any predecessor or successor corporation,  whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise,  all such liability being, by the acceptance
hereof  and as part of the  consideration  for the  issuance  hereof,  expressly
waived and released.

         The  Holder of any  Debenture  has the right,  exercisable  at any time
through the close of business  (New York time) on September 30, 2012 (or, in the
case of a Debenture called for redemption, prior to the close of business on the
Business  Day  prior to the  corresponding  redemption  date),  to  convert  the
principal amount thereof (or any portion thereof that is an integral multiple of
$50) into shares of Common Stock at the initial conversion rate of 0.8914 shares
of Common Stock



                                       45
<PAGE>

for each  Debenture  (equivalent  to a  Conversion  Price of $56.09 per share of
Common Stock), subject to adjustment under certain circumstances.

         To  convert  a  Debenture,  a  Holder  must  (a)  complete  and  sign a
conversion notice  substantially in the form attached hereto,  (b) surrender the
Debenture  to a  Conversion  Agent,  (c)  furnish  appropriate  endorsements  or
transfer  documents if required by the Conversion Agent and (d) pay any transfer
or similar tax, if required.  If a Debenture is surrendered for conversion after
the close of business on any regular  record date for payment of a  Distribution
and before the  opening of business on the  corresponding  Distribution  payment
date, then,  notwithstanding  such conversion,  the Distribution payable on such
Distribution  payment  date will be paid in cash to the person in whose name the
Debenture is registered at the close of business on such record date, and (other
than a  Debenture  or a  portion  of a  Debenture  called  for  redemption  on a
redemption  date  occurring  after  such  record  date  and on or  prior to such
Distribution  payment date) when so surrendered  for  conversion,  the Debenture
must be accompanied by payment of an amount equal to the Distribution payable on
such Distribution payment date. The number of shares issuable upon conversion of
a Debenture is  determined  by dividing the  principal  amount of the  Debenture
converted  by the  Conversion  Price  in  effect  on  the  Conversion  Date.  No
fractional  shares will be issued upon  conversion but a cash adjustment will be
made for any  fractional  interest.  The  outstanding  principal  amount  of any
Debenture  shall be  reduced  by the  portion of the  principal  amount  thereof
converted into shares of Common Stock.

                   , 199



The First National Bank of
 Chicago
One First National Plaza
Chicago, Illinois 60670-0126

Dear Sirs:

         In connection with our proposed  transfer of 5.50% Junior  Subordinated
Debentures due 2012 described  below (the  "Debentures")  of The AES Corporation
(the "Issuer"), we confirm that:

         1.   We have received a copy of the Offering  Memorandum (the "Offering
              Memorandum"),  dated October 24, 1997,  relating to the Debentures
              and the  undersigned  agrees  to be bound by,  and not to  resell,
              pledge or otherwise  transfer the Debentures  except in compliance
              with, such  restrictions  and conditions and the Securities Act of
              1933, as amended (the "Securities Act").

         2.   We understand  that any  subsequent  transfer of the Debentures is
              subject to certain  restrictions  and  conditions set forth in the
              Indenture as amended by the second supplemental indenture relating
              to the Debentures and the  undersigned  agrees to be bound by, and
              not to resell,  pledge or otherwise transfer the Debentures except
              in compliance  with,  such  restrictions  and  conditions  and the
              Securities Act of 1933, as amended (the "Securities Act").

         3.   We understand  that the offer and the sale of the  Debentures  has
              not  been  registered  under  the  Securities  Act,  and  that the
              Debentures  may not be offered or sold except as  permitted in the
              following  sentence.  We agree, on our own behalf and on behalf of
              any accounts for which we are acting as hereinafter  stated,  that
              if we should sell any  Debentures or Common Stock  (together,  the
              "Securities")  prior  to  the  expiration  of the  holding  period
              applicable  to sales of the security  evidenced  hereby under Rule
              144(k) under the Securities Act (or any successor  provision),  we
              will do so only (A) to The AES Corporation  (the "Company") or any
              subsidiary  thereof,  (B) inside the United  States in  accordance
              with Rule 144A under the Securities Act to a



                                       51
<PAGE>


              "qualified  institutional buyer" (as defined therein),  (C) inside
              the United States to an  institutional  "accredited  investor" (as
              defined  below)  that,  prior to such  transfer,  furnishes to the
              Trustee a signed letter  containing  certain  representations  and
              agreements  relating  to  the  restrictions  on  transfer  of  the
              Debenture  (the  form of which  letter  can be  obtained  from the
              Trustee) and, if such transfer is in respect of Debenture  with an
              aggregate liquidation preference of less than $250,000, an opinion
              of counsel  acceptable  to the  Company  that such  transfer is in
              compliance  with the Securities Act, (D) outside the United States
              in  accordance  with the Rule 904  under  the  Securities  Act (E)
              pursuant to the exemption from  registration  provided by Rule 144
              under the  Securities  Act (if  available)  or (F)  pursuant to an
              effective  registration statement under the Securities Act, and we
              further  agree to  provide  to any  person  purchasing  any of the
              Debenture from us a notice advising such purchaser that resales of
              the Debenture are restricted as stated herein.

         4.   We understand  that, on any proposed resale of any Securities,  we
              will be  required  to furnish to the Issuer and the  Trustee  such
              certifications, legal opinions and other information as the Issuer
              and the  Trustee  may  reasonably  require  to  confirm  that  the
              proposed sale complies with the foregoing restrictions. We further
              understand that the Securities  purchased by us will bear a legend
              to the foregoing effect.

         5.   We are a institutional  "accredited  investor" (as defined in rule
              501(a)(1),  (2), (3) or (7) of  Regulation D under the  Securities
              Act) and have such  knowledge  and  experience  in  financial  and
              business  matters as to be capable  of  evaluating  the merits and
              risks of our  investment in the Preferred  Securities,  and we and
              any  accounts  for which we are  acting  are each able to bear the
              economic risks of our or their investment.

         6.   We are acquiring the Debenture purchased by us for our own account
              for  one or more  accounts  (each  of  which  is an  institutional
              "accredited  investor")  as to  each of  which  we  exercise  sole
              investment discretion.

         The Issuer and the  Trustee  are  entitled to rely upon this letter and
are  irrevocably  authorized  to  produce  this  letter or a copy  hereof to any
interested party in any  administrative or legal proceedings or official inquiry
with respect to the matters covered hereby.

         prepare and file with the SEC a Registration



<PAGE>

                                      -5-


         Statement for an offering to be made on a continuous  basis pursuant to
         Rule 415 covering all of the Registrable Securities (the "Initial Shelf
         Registration"). The Registrants shall use their reasonable best efforts
         to file with the SEC the Initial Shelf  Registration on or prior to the
         Filing Date.  The Initial  Shelf  Registration  shall be on Form S-3 or
         another  appropriate  form permitting  registration of such Registrable
         Securities  for  resale  by  such  holders  in the  manner  or  manners
         designated  by  them  (including,   without  limitation,  one  or  more
         underwritten   offerings).   The  Registrants   shall  not  permit  any
         securities other than the Registrable  Securities to be included in the
         Initial Shelf  Registration or any Subsequent  Shelf  Registration  (as
         defined below). The Registrants shall use their reasonable best efforts
         to cause the Initial Shelf  Registration to be declared effective under
         the  Securities  Act on or prior to the  180th  day  after  the  filing
         thereof  with  the SEC  and to  keep  the  Initial  Shelf  Registration
         continuously effective under the Securities Act until the date which is
         24 months  from the Issue Date  (subject to  extension  pursuant to the
         last paragraph of Section 4 hereof) (the  "Effectiveness  Period"),  or
         such shorter period ending when (i) none of the  Securities  constitute
         Registrable Securities or (ii) a Subsequent Shelf Registration covering
         all of the Registrable Securities has been declared effective under the
         Securities Act.

              (b)  Subsequent  Shelf  Registrations.   If  the   Initial   Shelf
         Registration  or  any  Subsequent  Shelf  Registration   ceases  to  be
         effective for any reason at any time during the  Effectiveness  Period,
         the Registrants  shall use their  reasonable best efforts to obtain the
         prompt  withdrawal of any order suspending the  effectiveness  thereof,
         and  in  any  event  shall   within  45  days  of  such   cessation  of
         effectiveness  amend  the  Shelf  Registration  in a manner  reasonably
         expected  to  obtain  the  withdrawal  of  the  order   suspending  the
         effectiveness  thereof,  or file  an  additional  "shelf"  Registration
         Statement  pursuant  to  Rule  415  covering  all  of  the  Registrable
         Securities (a "Subsequent Shelf  Registration").  If a Subsequent Shelf
         Registration is filed, the Registrants  shall use their reasonable best
         efforts  to cause the  Subsequent  Shelf  Registration  to be  declared
         effective  as soon as  practicable  after such  filing and to keep such
         Registration Statement continuously effective for a period equal to the
         number of days in the Effectiveness Period less the aggregate number of
         days during  which the Initial  Shelf  Registration  or any  Subsequent
         Shelf Registration was previously continuously effective. As

                                      -6-


         used  herein the term  "Shelf  Registration"  means the  Initial  Shelf
         Registration and any Subsequent Shelf Registration.

              (c)  Supplements and Amendments.  The  Registrants  shall promptly
         supplement and amend the Shelf  Registration  if required by the rules,
         regulations or instructions  applicable to the  registration  form used
         for such Shelf  Registration,  if required by the Securities Act, or if
         reasonably  requested by the Holders of a majority of the shares of the
         Registrable Securities covered by such Registration Statement or by any
         underwriter of such Registrable Securities.

3.  Liquidated Damages

              (a)  The Registrants and the  Initial  Purchasers  agree  that the
         Holders  of   Registrable   Securities   will  suffer  damages  if  the
         Registrants  fail to fulfill their  obligations  under Section 2 hereof
         and that it would  not be  feasible  to  ascertain  the  extent of such
         damages with precision.  Accordingly,  the Registrants agree to pay, as
         liquidated  damages,  additional  cumulative cash  distributions on the
         Registrable Securities  ("Liquidated Damages") (i) if the Initial Shelf
         Registration  Statement is not declared  effective by the Commission on
         or prior to the Effectiveness Date and (ii) if the effectiveness of the
         Initial  Shelf   Registration   Statement  for  resales  thereunder  is
         suspended at any time during the  Effectiveness  Period in excess of 30
         days  in  any  consecutive  three  month  period  or  60  days  in  any
         consecutive  12-month  period (the "Black Out  Period"),  then, in each
         case,  Liquidated  Damages shall accrue on the  Registrable  Securities
         included  or that  should  have  been  included  in  such  Registration
         Statement  over and above the  stated  dividend  at a rate of $0.25 per
         TECON per annum for the first 90 days and increasing to $0.50 per TECON
         per annum  thereafter,  commencing on (x) the 181st day after the Issue
         Date in the case of clause (i) above and (y) the day such Initial Shelf
         Registration  Statement  ceases to be  effective in excess of the Black
         Out Period in the case of clause (ii) above;

provided,  however, that (1) upon the effectiveness of the Shelf Registration as
required  hereunder (in the case of clause (a)(i) of this Section 3) or (2) upon
the effectiveness of the Shelf Registration which had ceased to remain effective
(in  the  case  of  (a)(ii)  of  this  Section  3),  Liquidated  Damages  on the



<PAGE>

                                       -7-


Registrable Securities as a result of such clause, shall cease to accrue.

              (b)  The Registrants shall notify the Trustees within one business
         day after  each and every  date on which an event  occurs in respect of
         which Liquidated  Damages is required to be paid (an "Event Date"). The
         Registrants  shall pay the  Liquidated  Damages due on the  Registrable
         Securities  by paying an  increased  cash  dividend  on the  applicable
         quarterly  dividend  payment date,  or, if cash dividends are not being
         paid on the TECONS in accordance with the Declaration,  by accumulating
         dividends  at the higher  rate.  The  Liquidated  Damages  due shall be
         payable  on  each  dividend  payment  date  to  the  record  Holder  of
         Registrable  Securities  entitled to receive the dividend payment to be
         made on such  date as set  forth  in the  Declaration.  The  amount  of
         Liquidated  Damages will be determined by  multiplying  the  applicable
         Liquidated Damages by the number of shares of the affected  Registrable
         Securities of such Holders,  multiplied by a fraction, the numerator of
         which is the number of days such  Liquidated  Damages  were  applicable
         during such period (determined on the basis of a 360-day year comprised
         of twelve 30-day months and, in the case of a partial month, the actual
         number of days  elapsed),  and the  denominator  of which is 360.  Each
         obligation  to  pay  Liquidated  Damages  shall  be  deemed  to  accrue
         immediately  following the occurrence of the applicable Event Date. The
         parties hereto agree that the Liquidated  Damages  provided for in this
         Section 3 constitutes a reasonable  estimate of the damages that may be
         incurred by Holders of Registrable  Securities by reason of the failure
         of  a  Shelf  Registration  to  be  declared  effective  or  to  remain
         effective, as the case may be, in accordance with this Section 3.

4.  Registration Procedures

         In  connection  with the  registration  of any  Registrable  Securities
pursuant to Section 2 hereof, the Registrants shall effect such registrations to
permit the sale of such  Registrable  Securities in accordance with the intended
method or methods of disposition  thereof,  and pursuant thereto the Registrants
shall:

              (a)  Use their  reasonable  best  efforts to prepare and file with
         the SEC, as soon as practicable  after the date hereof but in any event
         prior to the Filing Date, a  Registration  Statement as  prescribed  by
         Section 2, and to use

                                      -8-


         their reasonable best efforts to cause such  Registration  Statement to
         become  effective  and remain  effective as provided  herein,  provided
         that,  before  filing any  Registration  Statement or Prospectus or any
         amendments or supplements  thereto,  the Registrants shall upon written
         request furnish to and afford the Holders of the Registrable Securities
         (which  in the case of  Registrable  Securities  in the form of  global
         certificates  shall be The Depository Trust Company ("DTC")) covered by
         such Registration  Statement, a reasonable opportunity to review copies
         of  all  such  documents  (including  copies  of  any  documents  to be
         incorporated by reference therein and all exhibits thereto) proposed to
         be filed.

              (b)  Prepare  and  file   with  the  SEC   such   amendments   and
         post-effective  amendments to each Shelf Registration Statement, as the
         case may be, as may be  necessary to keep such  Registration  Statement
         continuously  effective for the Effectiveness Period; cause the related
         Prospectus to be  supplemented by any required  Prospectus  supplement,
         and as so supplemented to be filed pursuant to Rule 424 (or any similar
         provisions then in force) under the Securities Act; and comply with the
         provisions  of the  Securities  Act, the Exchange Act and the rules and
         regulations  of the SEC  promulgated  thereunder  applicable to it with
         respect  to  the   disposition  of  all  securities   covered  by  such
         Registration  Statement  as so  amended  or in  such  Prospectus  as so
         supplemented.

              (c)  Notify the selling Holders of Registrable Securities who have
         provided the Registrants  with their names and addresses  promptly (but
         in any event  within two  business  days),  and confirm  such notice in
         writing,  (i)  when  a  Prospectus  or  any  Prospectus  supplement  or
         post-effective  amendment  has  been  filed,  and,  with  respect  to a
         Registration Statement or any post-effective  amendment,  when the same
         has become effective under the Securities Act (including in such notice
         a written statement that any Holder may, upon request,  obtain, without
         charge,   one  conformed  copy  of  such   Registration   Statement  or
         post-effective  amendment including financial statements and schedules,
         documents  incorporated  or deemed to be  incorporated by reference and
         exhibits), (ii) of the issuance by the SEC of any stop order suspending
         the  effectiveness  of  a  Registration   Statement  or  of  any  order
         preventing or suspending the use of any  preliminary  prospectus or the
         initiation of any proceedings for that purpose, (iii) of the receipt by
         the Registrants of any  notificat-



<PAGE>

                                      -9-


         ion with respect to the  suspension of the  qualification  or exemption
         from   qualification  of  a  Registration   Statement  or  any  of  the
         Registrable  Securities for offer or sale in any  jurisdiction,  or the
         initiation or threatening  of any proceeding for such purpose,  (iv) of
         the happening of any event or any information becoming known that makes
         any statement made in such Registration Statement or related Prospectus
         or any document  incorporated or deemed to be  incorporated  therein by
         reference untrue in any material respect or that requires the making of
         any changes in such Registration Statement,  Prospectus or documents so
         that, in the case of the  Registration  Statement,  it will not contain
         any untrue  statement of a material  fact or omit to state any material
         fact required to be stated  therein or necessary to make the statements
         therein not misleading, and that in the case of the Prospectus, it will
         not contain any untrue  statement  of a material  fact or omit to state
         any material  fact  required to be stated  therein or necessary to make
         the statements  therein,  in the light of the circumstances under which
         they were made, not misleading,  and (v) of the Registrants' reasonable
         determination  that  a  post-effective   amendment  to  a  Registration
         Statement would be appropriate.

              (d)  Use their reasonable  best efforts to prevent the issuance of
         any order suspending the  effectiveness of a Registration  Statement or
         of any  order  preventing  or  suspending  the use of a  Prospectus  or
         suspending the qualification  (or exemption from  qualification) of any
         of the Registrable Securities for sale in any jurisdiction, and, if any
         such order is issued,  to use their  reasonable  best efforts to obtain
         the withdrawal of any such order at the earliest possible moment.

              (e)  If  requested  by the  Holders of a majority of the shares of
         the   Registrable   Securities   being  sold  in  connection   with  an
         underwritten   offering,  (i)  promptly  incorporate  in  a  prospectus
         supplement or post-effective amendment such information as such Holders
         reasonably  request to be included  therein,  or (ii) make all required
         filings of such prospectus supplement or such post-effective  amendment
         as soon as practicable after the Registrants have received notification
         of the matters to be  incorporated  in such  prospectus  supplement  or
         post-effective amendment.

              (f)  Furnish to each selling Holder of Registrable Securities,  if
         any, without charge, one conformed copy of



<PAGE>

                                      -10-


         the  Registration  Statement  or  Statements  and  each  post-effective
         amendment thereto, including financial statements and schedules, and if
         requested,  all  documents  incorporated  or deemed to be  incorporated
         therein by reference and all exhibits.

              (g)  Deliver to each selling  Holder  of  Registrable  Securities,
         without  charge,  as many  copies  of the  Prospectus  or  Prospectuses
         (including  each form of preliminary  prospectus) and each amendment or
         supplement thereto and any documents  incorporated by reference therein
         as such  Persons  may  reasonably  request;  and,  subject  to the last
         paragraph of this Section 4, the Registrants  hereby consent to the use
         of such Prospectus and each amendment or supplement  thereto by each of
         the selling holders of Registrable  Securities and the  underwriters or
         agents,  if any, and dealers (if any), in connection  with the offering
         and sale of the Registrable  Securities  covered by such Prospectus and
         any amendment or supplement thereto.

              (h)  Prior to any public  offering of Registrable  Securities,  to
         use their  reasonable  best  efforts to  register  or  qualify,  and to
         cooperate  with  the  selling  Holders  of  Registrable  Securities  in
         connection with the  registration or  qualification  (or exemption from
         such registration or qualification) of such Registrable  Securities for
         offer  and  sale  under  the  securities  or  Blue  Sky  laws  of  such
         jurisdictions within the United States as any selling Holder reasonably
         requests in writing,  provided that where  Registrable  Securities  are
         offered other than through an  underwritten  offering,  the Registrants
         agree to cause their  counsel to perform  Blue Sky  investigations  and
         file registrations and qualifications  required to be filed pursuant to
         this Section 4(h);  keep each such  registration or  qualification  (or
         exemption  therefrom)  effective  during the period  such  Registration
         Statement  is  required to be kept  effective  and do any and all other
         reasonable  acts  or  things  necessary  or  advisable  to  enable  the
         disposition in such jurisdictions of the Registrable Securities covered
         by the  applicable  Registration  Statement,  provided that neither the
         Company nor the Trust shall be required to (A) qualify  generally to do
         business in any  jurisdiction  where it is then so qualified,  (B) take
         any action that would  subject it to general  service of process in any

              (i)  Reasonably cooperate with the selling  Holders of Registrable
         Securities  and the managing  underwriters,  if any, to facilitate  the
         timely   preparation   and   delivery  of   certificates   representing
         Registrable  Securities to be sold, which  certificates  shall not bear
         any  restrictive  legends and shall be in a form  eligible  for deposit
         with DTC; and enable such  Registrable  Securities  to be registered in
         such names as the  managing  underwriter  or  underwriters,  if any, or
         Holders may request.

              (j)  Use their reasonable  best  efforts to cause the  Registrable
         Securities covered by the Registration  Statement to be registered with
         or  approved  by such other  United  States  governmental  agencies  or
         authorities  of the  United  States as may be  necessary  to enable the
         seller or sellers  thereof or the  underwriters,  if any, to consummate
         the  disposition  of  such  Registrable  Securities,  except  as may be
         required solely as a consequence of the nature of such selling Holder's
         business,   in  which  case  the  Registrants  will  cooperate  in  all
         reasonable respects with the filing of such Registration  Statement and
         the granting of such approvals.

              (k)  Upon the occurrence of any event  contemplated  by  paragraph
         4(c)(iv)  or 4(c)(v)  above,  as promptly  as  practicable  prepare and
         (subject  to  Section  4(a)  above)  file  with the SEC,  solely at the
         expense of the Registrants, a supplement or post-effective amendment to
         the Registration Statement or a supplement to the related Prospectus or
         any  document  incorporated  or deemed to be  incorporated  therein  by
         reference,  or file any other required  document so that, as thereafter
         delivered to the purchasers of the  Registrable  Securities  being sold
         thereunder, any such Prospectus will not contain an untrue statement of
         a material  fact or omit to state a material fact required to be stated
         therein or necessary to make the  statements  therein,  in the light of
         the circumstances under which they were made, not misleading.

              (l)  Use their reasonable  best  efforts to cause the  Registrable
         Securities  covered by a  Registration  Statement  to be rated with the
         appropriate  rating  agencies,  if so  requested  by the  Holders  of a
         majority  of the  shares  of  Registrable  Securities  covered  by such
         Registration Statement or the managing underwriters, if any.

              (m)  Prior  to  the  effective  date  of  the  first  Registration
         Statement  relating  to the  Registrable  Securities,



<PAGE>

                                      -12-


         (i) provide the Trustees with printed  certificates for the Registrable
         Securities  in a form  eligible for deposit with DTC and (ii) provide a
         CUSIP number for the Registrable Securities.

              (n)  Provide an indenture  trustee  for  the  Junior  Subordinated
         Debentures  and cause the Indenture  and the Guarantee  Agreement to be
         qualified  under the TIA not later than the effective date of the first
         Registration Statement relating to the Registrable  Securities;  and in
         connection  therewith,  cooperate  with the trustee under the Indenture
         and the holders of the Registrable  Securities,  to effect such changes
         to the Indenture and the Guarantee Agreement as may be required for the
         Indenture and the Guarantee  Agreement to be so qualified in accordance
         with the terms of the TIA; and  execute,  and use its  reasonable  best
         efforts  to cause such  trustee to  execute,  all  documents  as may be
         required to effect  such  changes,  and all other  forms and  documents
         required  to be filed  with the SEC to  enable  the  Indenture  and the
         Guarantee Agreement to be so qualified in a timely manner.

              (o)  Comply in all material respects with all applicable rules and
         regulations   of  the  SEC  and  make   generally   available   to  its
         securityholders earning statements satisfying the provisions of Section
         11(a) of the  Securities  Act and Rule 158  thereunder  (or any similar
         rule promulgated  under the Securities Act) no later than 90 days after
         the end of any 12-month  period (i) commencing at the end of any fiscal
         quarter in which  Registrable  Securities are sold to underwriters in a
         firm commitment or best efforts  underwritten  offering and (ii) if not
         sold to underwriters  in such an offering,  commencing on the first day
         of the first fiscal  quarter of the Company after the effective date of
         a Shelf  Registration  Statement,  which  statements  shall  cover said
         12-month periods.

              (p)  Reasonably   cooperate   with  each  seller  of   Registrable
         Securities covered by any Registration  Statement  participating in the
         disposition of such Registrable Securities and their respective counsel
         in  connection  with any filings  required to be made with the National
         Association of Securities Dealers, Inc. (the "NASD").

              (q)  Use their reasonable  best  efforts  to take all other  steps
         necessary  to effect the  registration  of the  Registrable  Securities
         covered by a Registration Statement contemplated hereby.


<PAGE>

                                      -13-


         The  Registrants  may require each seller of Registrable  Securities to
furnish  to the  Registrants  such  information  regarding  such  seller and the
distribution of such Registrable Securities as the Registrants may, from time to
time, reasonably request. The Registrants may exclude from such registration the
Registrable  Securities  of any seller who  unreasonably  fails to furnish  such
information  within a reasonable time after receiving such request.  Each seller
as to which  any  Shelf  Registration  is being  effected  is deemed to agree to
furnish promptly to the Registrants all information  required to be disclosed in
order to make the  information  previously  furnished to the Registrants by such
seller not materially misleading.

         Each Holder of  Registrable  Securities  agrees by  acquisition of such
Registrable  Securities that, upon receipt of any notice from the Registrants of
the happening of any event of the kind described in Section 4(c)(ii), 4(c)(iii),
4(c)(iv), or 4(c)(v), such Holder will forthwith discontinue disposition of such
Registrable  Securities  covered by such  Registration  Statement or  Prospectus
until  such  holder's  receipt  of the  copies of the  supplemented  or  amended
Prospectus  contemplated by Section 4(k), or until it is advised in writing (the
"Advice") by the  Registrants  that the use of the applicable  Prospectus may be
resumed,  and has received copies of any amendments or supplements  thereto.  In
the event the Registrants shall give any such notice,  the Effectiveness  Period
shall be extended  by the number of days  during such period from and  including
the date of the giving of such notice to and including the date when each seller
of Registrable  Securities  covered by such  Registration  Statement  shall have
received (x) the copies of the supplemented or amended  Prospectus  contemplated
by Section 4(k) or (y) the Advice.

5.  Registration Expenses

         All fees and expenses incident to the performance of or compliance with
this Agreement by the Registrants  shall be borne by the Registrants  whether or
not a Shelf  Registration  is filed or  becomes  effective,  including,  without
limitation, (i) all registration and filing fees (including, without limitation,
(A) fees with respect to filings required to be made with the NASD in connection
with an underwritten offering and (B) fees and expenses of compliance with state
securities or Blue Sky laws (including, without limitation,  reasonable fees and
disbursements  of  counsel in  connection  with Blue Sky  qualifications  of the
Registrable  Securities and  determination of the eligibility of the Registrable
Securities for  investment  under the laws of such  jurisdictions  in the United
States as

                                      -14-


provided  in  Section  4(h)),   (ii)  printing  expenses   (including,   without
limitation,  expenses of printing  certificates for Registrable  Securities in a
form eligible for deposit with DTC and of printing  prospectuses if the printing
of  prospectuses  is  requested  by the  managing  underwriters,  if any, or, in
respect of Registrable Securities, by the Holders of a majority of shares of the
Registrable Securities included in any Registration Statement), (iii) messenger,
telephone and delivery expenses,  (iv) fees and disbursements of counsel for the
Registrants,  (v) fees and  disbursements  of all independent  certified  public
accountants for the  Registrants,  (vi) rating agency fees, (vii) Securities Act
liability insurance,  if the Registrants desire such insurance,  (viii) fees and
expenses  of all  other  Persons  retained  by the  Registrants,  (ix)  internal
expenses of the Registrants  (including,  without  limitation,  all salaries and
expenses  of officers  and  employees  of the  Registrants  performing  legal or
accounting  duties),  (x) the  expense  of any annual  audit,  (xi) the fees and
expenses  incurred  in  connection  with the  listing  of the  securities  to be

relating  to  printing,   word  processing  and  distributing  all  Registration
Statements, underwriting agreements, securities sales agreements, indentures and
any other documents  necessary in order to comply with this Agreement and (xiii)
fees and expenses of the Trustees and the trustee under the Indenture (including
reasonable fees and expenses of counsel to such trustees).

6.  Indemnification

         The  Registrants  agree,  jointly and severally,  to indemnify and hold
harmless each Holder of  Registrable  Securities,  the officers and directors of
each such person,  and each person,  if any, who controls any such person within
the meaning of Section 15 of the  Securities  Act or Section 20 of the  Exchange
Act (each,  a  "Participant"),  from and  against  any and all  losses,  claims,
damages,  liabilities  and judgments  caused by any untrue  statement or alleged
untrue statement of a material fact contained in any  Registration  Statement or
Prospectus (as amended or supplemented  if the Registrants  shall have furnished
any amendments or supplements thereto) or any preliminary prospectus,  or caused
by any omission or alleged omission to state therein a material fact required to
be stated  therein or necessary to make the statements  therein not  misleading,
except  insofar as such losses,  claims,  damages,  liabilities or judgments are
caused by any such untrue  statement or omission or alleged untrue  statement or
omission based upon information relating to any Participant furnished in writing
to the  Registrants  by or on  behalf  of  such  Participant  expressly  for use


<PAGE>

                                     -15-


therein; provided,  however, that the foregoing indemnity agreement with respect
to any preliminary  prospectus shall not inure to the benefit of any Participant
(or to the benefit of any person  controlling  such  Participant)  from whom the
person  asserting any such losses,  claims,  damages,  liabilities  or judgments
purchased Registrable Securities if a copy of the Prospectus (as then amended or
supplemented  if  the  Registrants   shall  have  furnished  any  amendments  or
supplements  thereto) was not sent or given by or on behalf of such  Participant
to such person, if required by law so to have been delivered, at or prior to the
written confirmation of the sale of such Registrable  Securities to such person,
and if the  Prospectus  (as so  amended  or  supplemented)  would have cured the
defect giving rise to such losses, claims, damages, liabilities or judgments.

         Each Participant will be required to agree,  severally and not jointly,
to indemnify and hold harmless each of the Company and the Trust, its respective
directors,  officers  and each  person,  if any, who controls the Company or the
Trust  within the meaning of Section 15 of the  Securities  Act or Section 20 of
the  Exchange  Act to the  same  extent  as the  foregoing  indemnity  from  the
Registrants to each Participant, but only with reference to information relating
to such  Participant  furnished in writing to the Registrants by or on behalf of
such Participant expressly for use in any Registration  Statement or Prospectus,
any  amendment  or  supplement  thereto,  or  any  preliminary  prospectus.  The
liability of any  Participant  under this paragraph shall in no event exceed the
proceeds  received  by such  Participant  from sales of  Registrable  Securities
giving rise to such obligations.

         In case any action  shall be brought  against  any person in respect of
which  indemnity  may  be  sought  pursuant  to  either  of  the  two  preceding
paragraphs,  such person (the  "Indemnified  Person") shall promptly  notify the
person against whom such indemnity may be sought (the "Indemnifying  Person") in
writing and the Indemnifying Person shall assume the defense thereof,  including
the employment of counsel reasonably  satisfactory to the Indemnified Person and
payment of all fees and expenses. Any Indemnified Person shall have the right to
employ  separate  counsel in any such  action  and  participate  in the  defense
thereof,  but the fees and expenses of such  counsel  shall be at the expense of
such  Indemnified  Person  unless (i) the  employment  of such  counsel has been
specifically  authorized  in  writing  by  the  Indemnifying  Person,  (ii)  the
Indemnifying Person has failed to assume the defense and employ counsel or (iii)
the named parties to any such action  (including any impleaded  parties) include
both the Indemnifying


<PAGE>

                                      -16-


Person and the  Indemnified  Person and such  Indemnified  Party shall have been
advised by such counsel that there may be one or more legal  defenses  available
to it  which  are  different  from  or  additional  to  those  available  to the
Indemnifying  Person (in which case the  Indemnifying  Person shall not have the
right to assume the defense of such action on behalf of such Indemnified Person,
it being  understood,  however,  that the  Indemnifying  Person  shall  not,  in
connection  with any one such action or separate  but  substantially  similar or
related  actions  in the  same  jurisdiction  arising  out of the  same  general
allegations or circumstances,  be liable for the reasonable fees and expenses of
more than one separate firm of attorneys (in addition to any local  counsel) for
all Indemnified Persons, and that all such fees and expenses shall be reimbursed
as they are  incurred).  Any such  separate firm for the  Participants  and such
control persons of  Participants  shall be designated in writing by Participants
who sold a majority  in  interest  of  Registrable  Securities  sold by all such
Participants  and any such separate firm for the  Registrants,  their respective
directors,  officers  and  such  control  persons  of the  Registrants  shall be
designated in writing by the Registrants.  The Indemnifying  Person shall not be
liable for any  settlement  of any such  action  effected  without  its  written
consent, but if settled with the written consent, the Indemnifying Person agrees
to indemnify and hold harmless any Indemnified  Person from and against any loss
or  liability  by  reason  of such  settlement.  Notwithstanding  the  foregoing
sentence,  if at  any  time  an  Indemnified  Person  shall  have  requested  an
Indemnifying Person to reimburse the Indemnified Person for fees and expenses of
counsel  as  contemplated   by  the  third  sentence  of  this  paragraph,   the
Indemnifying  Person  agrees that it shall be liable for any  settlement  of any
proceeding  effected  without  its  written  consent if (i) such  settlement  is
entered  into more than 10  business  days after  receipt  by such  Indemnifying
Person of the aforesaid request and (ii) such Indemnifying Person shall not have
reimbursed the  Indemnified  Person in accordance with such request prior to the
date of such settlement. No Indemnifying Person shall, without the prior written
consent of the  Indemnified  Person,  effect any  settlement  of any  pending or
threatened  proceeding  in respect of which any  Indemnified  Person is or could
have  been a party  and  indemnity  could  have been  sought  hereunder  by such
Indemnified Person,  unless such settlement includes an unconditional release of
such Indemnified Person from all liability on claims that are the subject matter
of such proceeding.

         If the Indemnification  provided for in the first and second paragraphs
of this  Section 6 is  unavailable  to an  Indemnified  Person in respect of any
losses, claims, damages, lia-



<PAGE>

                                      -17-


bilities or judgments referred to therein,  then each Indemnifying  Person under
such paragraph,  in lieu of indemnifying  such  Indemnified  Person  thereunder,
shall contribute to the amount paid or payable by such  Indemnified  Person as a
result  of such  losses,  claims,  damages,  liabilities  or  judgments  in such
proportion as is appropriate to reflect the relative fault of the Registrants on
the one hand and the  Participants  on the  other  hand in  connection  with the
statements  or  omissions  that  resulted  in  such  losses,  claims,   damages,
liabilities,   or   judgments   as  well  as  any   other   relevant   equitable
considerations.  The relative  fault of the  Registrants on the one hand and the
Participants  on the other hand shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged  omission to state a material  fact  relates to  information
supplied by the  Registrants or by the  Participants  and the parties'  relative
intent,  knowledge,  access to information and opportunity to correct or prevent
such statement or omission.

         The  parties  shall  agree that it would not be just and  equitable  if
contribution  pursuant  to the  prior  paragraph  were  determined  by pro  rata
allocation  (even  if the  Participants  were  treated  as one  entity  for such
purpose) or by any other method of allocation  that does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount  paid or  payable  by an  Indemnified  Person as a result of the  losses,
claims,  damages,  liabilities  or  judgments  referred  to in  the  immediately
preceding  paragraph shall be deemed to include,  subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such Indemnified
Person in connection with  investigating  or defending any such action or claim.
Notwithstanding  the  provisions  of this  Section  6, no  Participant  shall be
required  to  contribute  any amount in excess of the  amount by which  proceeds
received by such  Participant from sales of Registrable  Securities  exceeds the
amount of any damages that such  Participant  has otherwise been required to pay
by reason of such  untrue or alleged  untrue  statement  or  omission or alleged
omission. No person guilty of fraudulent  misrepresentation  (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to  contribution  from
any person who was not guilty of such fraudulent misrepresentation.

         The indemnity and contribution  agreements  contained in this Section 6
will  be in  addition  to any  liability  which  the  Indemnifying  Persons  may
otherwise have to the Indemnified Persons referred to above.

7.  Rule 144 and Rule 144A

         The Registrants covenant that they will file the reports required to be
filed by them under the  Securities  Act and the  Exchange Act and the rules and
regulations adopted by the SEC thereunder in a timely manner and, if at any time
the  Registrants  are not  required to file such  reports,  they will,  upon the
request of any Holder of Registrable  Securities,  make publicly available other
information  so long as necessary to permit sales  pursuant to Rule 144 and Rule
144A under the Securities Act. The Registrants  further  covenant that they will
take such further action as any Holder of Registrable  Securities may reasonably
request,  all to the extent  required from time to time to enable such holder to
sell Registrable Securities without registration under the Securities Act within
the  limitation of the  exemptions  provided by (a) Rule 144 and Rule 144A under
the  Securities  Act, as such rules may be amended from time to time, or (b) any
similar rule or regulation hereafter adopted by the SEC.

8.  Underwritten Registrations

         If any of the Registrable  Securities covered by any Shelf Registration
are to be sold in an underwritten  offering, the investment banker or investment
bankers and manager or managers  that will manage the offering  will be selected
by the  Holders  of a  majority  of the  shares of such  Registrable  Securities
included in such offering and be reasonably acceptable to the Registrants.

         No Holder of Registrable Securities may participate in any underwritten
registration  hereunder  unless  such  Holder (a)  agrees to sell such  Holder's
Registrable  Securities on the basis provided in any  underwriting  arrangements
approved by the Persons entitled  hereunder to approve such arrangements and (b)
completes  and executes  all  questionnaires,  powers of attorney,  indemnities,
underwriting  agreements  and other  documents  required under the terms of such
underwriting arrangements.

9.  Miscellaneous

              (a)  Remedies.  In the event of a breach by the Registrants of any
         of their respective  obligations  under this Agreement,  each Holder of
         Registrable  Securities,  in addition to being entitled to exercise all
         rights  provided  herein,  in  the  Declaration,   the  Indenture,  the
         Guarantee Agreement or, in the case of the Initial  Purchasers,  in the
         Purchase  Agreement or granted by law,  including  recov-



<PAGE>

                                      -19-


         ery of damages,  will be entitled to specific performance of its rights
         under this Agreement. The Registrants agree that monetary damages would
         not be  adequate  compensation  for any loss  incurred  by  reason of a
         breach by it of any of the  provisions  of this  Agreement  and  hereby
         further agree that, in the event of any action for specific performance
         in respect of such breach, the Registrants shall waive the defense that
         a remedy at law would be adequate.

              (b)  No Inconsistent  Agreements.  The Registrants have not, as of
         the  date  hereof,  entered  and  shall  not,  after  the  date of this
         Agreement,  enter  into  any  agreement  with  respect  to  any  of its
         respective  securities that is inconsistent  with the rights granted to
         the Holders of  Registrable  Securities in this  Agreement or otherwise
         conflicts with the provisions  hereof. The Registrants have not entered
         and will  not  enter  into any  agreement  with  respect  to any of its
         respective  securities which will grant to any Person piggy-back rights
         with respect to a Registration Statement.

              (c)  Adjustments Affecting Registrable Securities. The Registrants
         shall not, directly or indirectly,  take any action with respect to the
         Registrable  Securities  as a class  that  would  adversely  affect the
         ability  of the  Holders of  Registrable  Securities  to  include  such
         Registrable  Securities in a registration  undertaken  pursuant to this
         Agreement.

              (d)  Amendments and Waivers.  The  provisions  of this  Agreement,
         including the provisions of this sentence, may not be amended, modified
         or  supplemented,  and  waivers  or  consents  to  departures  from the
         provisions  hereof  may  not be  given,  unless  the  Registrants  have
         obtained  the written  consent of Holders of at least a majority of the
         Registrable  Securities.  Notwithstanding  the  foregoing,  a waiver or
         consent to depart from the  provisions  hereof with respect to a matter
         that  relates  exclusively  to the  rights of  Holders  of  Registrable
         Securities  whose  securities are being sold pursuant to a Registration
         Statement  and that does not  directly or  indirectly  affect,  impair,
         limit  or  compromise  the  rights  of  other  Holders  of  Registrable
         Securities  may be  given by  Holders  of at  least a  majority  of the
         Registrable  Securities  being sold by such  Holders  pursuant  to such
         Registration  Statement,  provided that the provisions of this sentence
         may not be amended,  modified or supplemented except in accordance with
         the provisions of the immediately preceding sentence.

         held by the  Registrants  or any of their  affiliates  (as such term is
         defined in Rule 405 under the  Securities  Act) shall not be counted in

waived  any Event of Default  with  respect  to the  Common  Securities  and its
consequences  until  all  Events  of  Default  with  respect  to  the  Preferred
Securities  have been cured,  waived by the Holders of Preferred  Securities  as
provided in this  Declaration  or otherwise  eliminated  and until all Events of
Default with respect to the Preferred  Securities have been so cured,  waived or
otherwise eliminated, the Property Trustee will be deemed to be acting solely on
behalf of the Holders of the  Preferred  Securities  and only the Holders of the
Preferred  Securities  will have the right to direct  the  Property  Trustee  in
accordance with the terms of this  Declaration or the  Securities.  In the event
that any Event of Default with respect to the Preferred  Securities is waived by
the Holders of Preferred Securities as provided in this Declaration, the Holders
of Common  Securities agree that such waiver shall also constitute the waiver of
such Event of Default  with  respect to the Common  Securities  for all purposes
under this  Declaration  without any further act, vote or consent of the Holders
of the Common  Securities.  Subject to the foregoing  provisions of this Section
2.06(b),  upon such waiver,  any such default shall cease to exist and any Event
of Default  with respect to the Common  Securities  arising  therefrom  shall be
deemed to have been  cured for every  purpose of this  Declaration,  but no such
waiver shall extend to any  subsequent or other default or Event of Default with
respect to the Common Securities or impair any right consequent thereon.

          (c) The right of any  Holder  of  Securities  to  receive  payment  of
Distributions  on the  Securities in accordance  with this  Declaration  and the
terms of the Securities set forth in Exhibits B and C on or after the respective
payment dates  therefor,  or to institute  suit for the  enforcement of any such
payment  on or after such  payment  dates,  shall not be  impaired  without  the
consent of such Holder.

          (d) As provided in the terms of the Securities set forth in Exhibits B
and C hereto,  a waiver of an Indenture Event of Default by the Property Trustee
at the written direction of the Holders of the Preferred Securities  constitutes
a waiver of the corresponding Event of Default under this Declaration in respect
of the Securities.

Regular Trustee;

         (k) to incur expenses which are necessary or incidental to carrying out
any of the purposes of the Trust;

         (l) to act as,  or  appoint  another  Person to act as,  registrar  and
transfer  agent  for the  Securities,  the  Regular  Trustees  hereby  initially

         (p) to take all action,  not inconsistent with this Declaration or with
applicable law, which the Regular  Trustees  determine in their discretion to be
reasonable  and  necessary or desirable  in carrying out the  activities  of the
Trust as set out in this Section 3.08, in order that:

         income tax purposes as an  association  taxable as a  corporation  or a
         partnership  and will be treated as a grantor  trust for United  States
         federal income tax purposes; and

              (iii) the Trust will comply with any  requirements  imposed by any
         taxing authority on holders of instruments  treated as indebtedness for

provided that such action does not adversely affect the interests of Holders;

         (q) to take all action  necessary to cause all  applicable  tax returns

Trust  Indenture  Act, to appoint  one or more Paying  Agents in addition to the

         The Regular Trustees must exercise the powers set forth in this Section
3.08 in a manner which is  consistent  with the  purposes  and  functions of the

         (a)  invest  any  proceeds  received  by the  Trust  from  holding  the
Debentures  but shall  promptly  distribute  all such  proceeds  to  Holders  of
Securities pursuant to the terms of this Declaration and of the Securities;

         (b) acquire any assets other than as expressly provided herein;

waive any past default  that is waivable  under  Section 6.06 of the  Indenture,

Property  Trustee  shall have  received  an  unqualified  opinion of  nationally
recognized  independent tax counsel  recognized as expert in such matters to the
effect  that such action  will not cause the Trust to be  classified  for United
States federal income tax purposes as an association taxable as a corporation or
partnership and that the Trust will continue to be classified as a grantor trust
for United States federal income tax purposes.

         SECTION 3.10. Powers and Duties of the Property Trustee.  (a) The legal
title to the Debentures  shall be owned by and held of record in the name of the
Property  Trustee in trust for the  benefit of the Trust and the  Holders of the
Securities.  The  right,  title and  interest  of the  Property  Trustee  to the
Debentures  shall  vest  automatically  in  each  Person  who may  hereafter  be
appointed  as Property  Trustee in  accordance  with Article 5. Such vesting and
cessation of title shall be effective whether or not conveyancing documents have
been executed and delivered.

         (b) The  Property  Trustee  shall not  transfer  its  right,  title and
interest in the Debentures to the Regular  Trustees or, if the Property  Trustee
does not also act as the Delaware Trustee, the Delaware Trustee.

         (c) The Property Trustee shall:

              (i) establish and maintain a segregated  non-interest bearing bank
         account (the "Property Account") in the name of and under the exclusive
         control  of the  Property  Trustee  on  behalf  of the  Holders  of the
         Securities  and on the  receipt of payments of funds made in respect of
         the Debentures  held by the Property  Trustee,  deposit such funds into
         the  Property  Account  and,  without any further  acts of the Property
         Trustee or the Regular Trustees,  promptly make payments to the Holders
         of the Preferred  Securities  and Common  Securities  from the Property
         Account in accordance with Section 6.01.  Funds in the Property Account
         shall be held uninvested,  and without  liability for interest thereon,
         until  disbursed  in  accordance  with this  Declaration.  The Property
         Account  shall  be an  account  which  is  maintained  with  a  banking
         institution  whose  long  term  unsecured  indebtedness  is  rated by a
         "nationally recognized  statistical rating organization",  as such term
         is defined for purposes of Rule




                                       20
<PAGE>



         436(g)(2) under the Securities Act, at least equal to (but in no  event
         less than "A" or the  equivalent) the rating assigned to the  Preferred
         Securities by a nationally recognized statistical rating  organization;

              (ii) engage in such  ministerial  activities as shall be necessary
         or  appropriate  to effect  promptly the  redemption  of the  Preferred
         Securities  and the Common  Securities to the extent the Debentures are
         redeemed or mature;

              (iii) upon notice of distribution  issued by the Regular  Trustees
         in accordance with the terms of the Preferred Securities and the Common
         Securities, engage in such ministerial activities as shall be necessary
         or appropriate to effect promptly the distribution pursuant to terms of
         the  Securities  of  Debentures  to  Holders  of  Securities  upon  the
         occurrence of a Special Event; and

              (iv) have the legal  power to exercise  all of the rights,  powers
         and privileges of a holder of the  Debentures  under the Indenture and,
         if an Event of Default occurs and is continuing,  the Property Trustee,
         subject to Section 2.06(b), shall for the benefit of the Holders of the
         Securities,  enforce its rights as holder of the  Debentures  under the
         Indenture,  subject  to the  rights  of the  Holders  of the  Preferred
         Securities  pursuant  to the terms of this  Declaration,  the  Business
         Trust Act and the Trust Indenture Act.

         (d) The Property Trustee shall take all actions and perform such duties
as may be specifically required of the Property Trustee pursuant to the terms of
the Securities set forth in Exhibits B and C hereto.

         (e) The Property  Trustee  shall take any Legal Action which arises out
of or in connection  with an Event of Default or the Property  Trustee's  duties
and  obligations  under this  Declaration,  the Business  Trust Act or the Trust
Indenture Act; provided  however,  that the holders of a Majority in liquidation
amount of the  Preferred  Securities  will  have the  right to direct  the time,
method and place of conducting any  proceeding  for any remedy  available to the
Property  Trustee or to direct the exercise of any trust or power conferred upon
the Property  Trustee under the  Declaration,  including the right to direct the
Property  Trustee to exercise  the  remedies  available to it as a holder of the
Debentures.  If the  Property  Trustee  fails to enforce  its  rights  under the
Debentures,  a Holder of Preferred  Securities,  to the extent permitted by law,
may institute a legal  proceeding  directly  against AES to enforce the Property
Trustee's  rights  under the  Debentures  without  first  instituting  any legal
proceeding  against the Property Trustee or any other Person;  provided further,
that, if an Event of Default has occurred and is continuing and




                                       21
<PAGE>


such event is  attributed  to the  failure of the  Sponsor  to pay  interest  or
principal on the  Debentures on the date such interest or principal is otherwise
payable (or in the case of redemption, on the redemption date), then a Holder of
Preferred  Securities  may directly  institute a proceeding  for  enforcement of
payment to such Holder of the principal of or interest on the Debentures  having
a principal  amount equal to the aggregate  liquidation  amount of the Preferred
Securities of such Holder (a "Holder Direct  Action") on or after the respective
due date  specified in the  Debentures.  In  connection  with such Holder Direct
Action, the rights of the Holders of the Common Securities will be subrogated to
the rights of such Holder of Preferred  Securities  to the extent of any payment
made by the  Sponsor to such  Holders of  Preferred  Securities  in such  Holder
Direct  Action.  Except as provided in the preceding  sentences,  the Holders of
Preferred  Securities will not be able to exercise directly any remedy available
to the Holders of the Debentures.

         (f) All moneys  deposited in the Property  Account,  and all Debentures
held by the  Property  Trustee for the benefit of the Holders of the  Securities
will not be subject to any right,  charge,  security interest,  lien or claim of
any kind in favor of, or for the benefit of the  Property  Trustee or its agents
or their creditors.

         (g) The Property Trustee shall,  within 90 days after the occurrence of
a default with respect to the Securities known to the Property Trustee, transmit
by mail, first class postage prepaid, to the holders of the Securities, as their
names and addresses  appear upon the register,  notice of all such defaults with
respect to the Securities, unless such defaults shall have been cured before the
giving of such  notice (the term  "defaults"  for the  purposes of this  Section
3.10(g) being hereby defined to be an Indenture Event of Default,  not including
any periods of grace  provided  for in the  Indenture  and  irrespective  of the
giving of any notice provided  therein);  provided,  that, except in the case of
default in the payment of the  principal of (or premium,  if any) or interest on
any of the  Debentures,  the Property  Trustee shall be protected in withholding
such notice if and so long as the board of directors, the executive committee or
a trust  committee of directors  and/or  Responsible  Officers,  of the Property
Trustee in good faith  determines  that the withholding of such notice is in the
interests of the Holders of the  Securities.  The Property  Trustee shall not be
deemed to have knowledge of any default,  except (i) a default in the payment of
principal, premium or interest on the Debentures or (ii) any default as to which
the Property Trustee shall have received written notice or a Responsible Officer
charged with the  administration of this Declaration shall have obtained written
notice.

         thereof  distributed to the Holders of Securities pursuant to the terms
         of the Securities; or

              (ii) a Successor  Property Trustee has been appointed and accepted
         that appointment in accordance with Article 5.

         (i) The  Property  Trustee  shall act as paying agent in respect of the

may authorize one or more Persons (each, a "Paying Agent") to pay Distributions,

to the Preferred Securities.  Any such Paying Agent shall comply with ss. 317(b)
of the Trust  Indenture  Act.  Any Paying  Agent may be removed by the  Property
Trustee,  after  consultation  with  the  Regular  Trustees,  at any  time and a
successor Paying Agent or additional  Paying Agents may be appointed at any time
by the Property Trustee, subject to Section 3.08(r).

         (j) The  Property  Trustee  shall  give  prompt  written  notice to the
Holders of the Securities of any notice  received by it from AES of its election
to defer  payments of interest  on the  Debentures  by  extending  the  interest
payment period with respect thereto.

         (k) Subject to this Section 3.10, the Property  Trustee shall have none
of the powers or the  authority  of the  Regular  Trustees  set forth in Section
3.08.

         (l) The Property  Trustee shall exercise the powers,  duties and rights
set forth in this Section 3.10 and Section 3.12 in a manner which is  consistent
with the purposes and  functions of the Trust set out in Section  3.05,  and the
Property  Trustee  shall  not take any  action  which is  inconsistent  with the
purposes and functions of the Trust set forth in Section 3.05.

         SECTION 3.11. Delaware Trustee.  Notwithstanding any other provision of
this Declaration other than Section  5.01(a)(3),  the Delaware Trustee shall not
be entitled to exercise any powers,  nor shall the Delaware  Trustee have any of
the  duties  and  responsibilities  described  in this  Declaration  (except  as
required  under  the  Business  Trust  Act) .  Except  as set  forth in  Section
5.01(a)(3),  the  Delaware  Trustee  shall be a Trustee for the sole and limited
purpose of fulfilling the requirements of ss. 3807 of the Business Trust Act. No
implied covenants or obligations shall be read into this Declaration against the
Delaware Trustee.

         SECTION 3.12.  Certain Rights and Duties of the Property  Trustee.  (a)
The Property Trustee, before the occurrence of an Event of Default and after the
curing of all Events of  Default  that may have  occurred,  shall  undertake  to
perform only




                                       23
<PAGE>


such duties as are  specifically set forth in this  Declaration,  and no implied
covenants shall be read into this Declaration  against the Property Trustee.  In
case an Event of  Default  has  occurred  (that  has not  been  cured or  waived
pursuant to Section  2.06),  the Property  Trustee  shall  exercise  such of the
rights and powers vested in it by this  Declaration,  and use the same degree of
care and skill in their  exercise,  as a prudent  person  would  exercise or use
under the circumstances in the conduct of his or her own affairs.

         (b) No provision of this Declaration  shall be construed to relieve the
Property Trustee from liability for its own negligent action,  its own negligent
failure to act or its own willful misconduct, except that:

              (i) prior to the  occurrence  of an Event of Default and after the
         curing or waiving of all such Events of Default that may have occurred:

                   (A) the duties and obligations of the Property  Trustee shall
              be   determined   solely  by  the  express   provisions   of  this
              Declaration,  and the Property  Trustee shall not be liable except
              for  the  performance  of  such  duties  and  obligations  as  are
              specifically  set  forth  in  this  Declaration,  and  no  implied
              covenants  or  obligations  shall be read  into  this  Declaration
              against the Property Trustee; and

                   (B) in the  absence of bad faith on the part of the  Property
              Trustee,  the Property  Trustee may  conclusively  rely, as to the
              truth  of the  statements  and  the  correctness  of the  opinions
              expressed therein,  upon any certificates or opinions furnished to
              the Property  Trustee and conforming to the  requirements  of this
              Declaration;  but in the case of any such certificates or opinions
              that by any  provision  hereof  are  specifically  required  to be
              furnished to the Property  Trustee,  the Property Trustee shall be
              under a duty to examine the same to determine  whether or not they
              conform to the requirements of this Declaration;

              (ii) the  Property  Trustee  shall not be liable  for any error of
         judgment  made in good faith by a  Responsible  Officer of the Property
         Trustee,  unless  it shall be  proved  that the  Property  Trustee  was
         negligent in ascertaining the pertinent facts;

              (iii) the Property Trustee shall not be liable with respect to any
         action  taken or omitted to be taken by it in good faith in  accordance
         with the  direction of the Holders as provided  herein  relating to the
         time,  method and place of  conducting  any  proceeding  for any remedy
         available to the




                                       24
<PAGE>


         Property Trustee  hereunder or under the Indenture,  or exercising  any
         trust  or  power  conferred  upon  the  Property  Trustee  under   this
         Declaration; and

              (iv) no provision of this  Declaration  shall require the Property
         Trustee  to expend or risk its own funds or  otherwise  incur  personal
         financial  liability in the  performance of any of its duties or in the
         exercise  of any of its rights or powers,  if it shall have  reasonable
         ground for  believing  that the repayment of such funds or liability is
         not  reasonably  assured to it under the terms of this  Declaration  or
         adequate  indemnity  against such risk or  liability is not  reasonably
         assured to it.

         (c) Subject to the provisions of Section 3.12(a) and (b):

              (i)  whenever  in the  administration  of  this  Declaration,  the
         Property  Trustee  shall deem it  desirable  that a matter be proved or
         established   prior  to  taking,   suffering  or  omitting  any  action
         hereunder,  the  Property  Trustee  (unless  other  evidence  is herein
         specifically  prescribed)  may, in the absence of bad faith on its part
         and, if the Trust is excluded from the definition of Investment Company
         solely by means of Rule 3a-7, subject to the requirements of Rule 3a-7,
         request  and rely  upon a  certificate,  which  shall  comply  with the
         provisions of ss. 314(e) of the Trust  Indenture Act, signed by any two
         of the Regular Trustees or by an authorized officer of the Sponsor,  as
         the case may be;

              (ii) The Property  Trustee (A) may consult with counsel (which may
         be counsel to the Sponsor or any of its  Affiliates and may include any
         of its  employees)  selected  by it in good faith and with due care and
         the written  advice or opinion of such  counsel  with  respect to legal
         matters  shall be full and complete  authorization  and  protection  in
         respect of any action  taken,  suffered or omitted by it  hereunder  in
         good faith and in reliance  thereon and in accordance  with such advice
         and  opinion  and  (B)  shall  have  the  right  at any  time  to  seek
         instructions concerning the administration of this Declaration from any
         court of competent jurisdiction;

              (iii) The Property Trustee may execute any of the trusts or powers
         hereunder  or perform  any duties  hereunder  either  directly or by or
         through  agents or  attorneys  and the  Property  Trustee  shall not be
         responsible  for any  misconduct or negligence on the part of any agent
         or attorney appointed by it in good faith and with due care;

              (iv) The Property Trustee shall be under no obligation to exercise
         any of the  rights or powers  vested in it by this  Declaration  at the
         request or




                                       25

         direction  of any Holders,  unless such Holders  shall have offered  to
         the Property  Trustee  reasonable  security and indemnity  against  the
         costs,   expenses   (including   attorneys'  fees  and  expenses)   and
         liabilities  that  might be  incurred  by it in  complying  with   such
         request or direction;  provided that nothing  contained in this  clause
         (iv) shall relieve the Property  Trustee of the  obligation,  upon  the
         occurrence of an Event of Default (which has not been cured or  waived)
         to  exercise  such  of the  rights  and  powers  vested  in it by  this
         Declaration,  and to use the same  degree  of care  and  skill in  this
         exercise,  as a  prudent  person  would  exercise  or  use  under   the
         circumstances in the conduct of his or her own affairs; and

              (v)  Any  action  taken  by the  Property  Trustee  or its  agents
         hereunder shall bind the Holders of the Securities and the signature of
         the  Property  Trustee  or its agents  alone  shall be  sufficient  and
         effective  to perform  any such  action;  and no third  party  shall be
         required to inquire as to the  authority of the Property  Trustee to so
         act, or as to its  compliance  with any of the terms and  provisions of
         this Declaration,  both of which shall be conclusively evidenced by the
         Property Trustee's or its agent's taking such action.

         SECTION  3.13.  Filing of  Amendments  to  Certificate  of  Trust.  The
Restated  Certificate of Trust as filed with the Secretary of State of the State
of  Delaware  on  November  1, 1996 and  restated  on March 27, 1997 is attached

otherwise determined by the Regular Trustees and except as otherwise required by

majority  of,  or if there are only  two,  both of,  the  Regular  Trustees  are
authorized to execute and deliver on behalf of the Trust any documents which the

this Declaration.

         SECTION  3.15.  Trustees  Not  Responsible  for Recitals or Issuance of

issuance of the  Securities the number of Trustees may be increased or decreased
solely by, and Trustees may be appointed, removed or replaced solely by, vote of
Holders of Common  Securities  representing a Majority in liquidation  amount of
the Common Securities voting as a class; provided that in any case:

              (i) the number of  Trustees  shall be at least five (5) unless the

         has its  principal  place of  business  in the  State of  Delaware  and
         otherwise is permitted to act as a Trustee  hereunder under the laws of

         principal  place of business in the State of Delaware and  otherwise is
         permitted to act as a Trustee  hereunder under the laws of the State of
         Delaware,  then the Property Trustee shall also be the Delaware Trustee
         and Section 3.11 shall have no application; and

              (iv)  there  shall at all times be a  Property  Trustee  hereunder

              (ii) be a corporation or national  banking  association  organized
         and doing  business  under the laws of the United  States of America or

         corporation,  national  banking  association or Person permitted by the
         Commission to act as an institutional trustee under the Trust Indenture
         Act,  authorized  under such laws to exercise  corporate  trust powers,
         having a combined  capital  and  surplus of at least  $50,000,000,  and
         subject to supervision or examination by Federal, State, Territorial or
         District of Columbia authority. If such corporation or national banking
         association publishes reports of condition at least annually,  pursuant
         to law or to the requirements of the supervising or examining authority
         referred to above,  then for the purposes of this Section  5.01(c)(ii),
         the combined capital and surplus of such corporation shall be deemed to
         be its  combined  capital  and  surplus as set forth in its most recent
         report of condition so published; and

              (iii)  if  the  Trust  is  excluded  from  the  definition  of  an

requirements of clauses  (i)-(iii) above, the Property Trustee shall immediately
resign in the manner and with the  effect  set out in  Section  5.02(d).  If the
Property  Trustee has or shall  acquire any  "conflicting  interest"  within the
meaning of ss. 310(b) of the Trust  Indenture Act, the Property  Trustee and the
Holders of the Common  Securities (as if such Holders were the obligor  referred
to in ss. 310(b) of the Trust  Indenture Act) shall in all respects  comply with
the provisions of ss. 310(b) of the Trust Indenture Act. The Preferred Guarantee
shall be deemed to be specifically

         (e) Any action taken by Holders of Common  Securities  pursuant to this
Article 5 shall be taken at a meeting of Holders of Common  Securities  convened
for such purpose or by written consent as provided in Section 12.02.

         (f) No  amendment  may be made to this  Section 5.01 which would change
any rights with respect to the number,  existence or appointment  and removal of
Trustees, except with the consent of each Holder of Common Securities.

         a class.

         (b) (i) The Trustee that acts as Property  Trustee shall not be removed

appointed and has accepted such  appointment by written  instrument  executed by
such  Successor  Property  Trustee and  delivered to the Regular  Trustees,  the
Sponsor and the Property Trustee being removed; and

              (ii) the  Trustee  that  acts as  Delaware  Trustee  shall  not be
         removed in accordance  with Section  5.02(a) until a successor  Trustee
         possessing the  qualifications to act as Delaware Trustee under Section
         5.1(a)(3) (a "Successor  Delaware  Trustee") has been appointed and has
         accepted such appointment by written instrument executed by such

         Successor Delaware Trustee and delivered to the Regular  Trustees,  the
         Sponsor and the Delaware Trustee being removed.

         (c) A Trustee appointed to office shall hold office until his successor
shall have been appointed or until his death, removal or resignation.

         (d) Any  Trustee  may resign  from  office  (without  need for prior or
subsequent  accounting)  by an instrument (a  "Resignation  Request") in writing
signed  by the  Trustee  and  delivered  to the  Sponsor  and the  Trust,  which
resignation  shall take effect upon such  delivery or upon such later date as is
specified therein; provided, however, that:

              (i) no such  resignation  of the Trustee that acts as the Property
         Trustee shall be effective until:

                   (A)   a   Successor    Property   Trustee    possessing   the
              qualifications  to act as Property  Trustee under Section  5.01(c)
              has been appointed and has accepted such appointment by instrument
              executed by such Successor  Property  Trustee and delivered to the
              Trust, the Sponsor and the resigning Property Trustee; or

                   (B) if the  Trust  is  excluded  from  the  definition  of an
              Investment Company solely by reason of Rule 3a-7, until the assets
              of the Trust  have been  completely  liquidated  and the  proceeds
              thereof distributed to the Holders of the Securities; and

              (ii) no such  resignation of the Trustee that acts as the Delaware
         Trustee shall be effective until a Successor  Delaware Trustee has been
         appointed and has accepted such  appointment by instrument  executed by
         such Successor Delaware Trustee and delivered to the Trust, the Sponsor
         and the resigning Delaware Trustee.

         (e) If no  Successor  Property  Trustee or Successor  Delaware  Trustee
shall have been  appointed and accepted  appointment as provided in this Section
5.02 within 60 days after delivery to the Sponsor and the Trust of a Resignation
Request,  the resigning  Property  Trustee or Delaware  Trustee may petition any
court of competent  jurisdiction for appointment of a Successor Property Trustee
or Successor  Delaware  Trustee.  Such court may thereupon after such notice, if
any, as it may deem proper and prescribe,  appoint a Successor  Property Trustee
or Successor Delaware Trustee, as the case may be.

         SECTION 5.03.  Vacancies  among  Trustees.  If a Trustee ceases to hold
office for any reason and the number of  Trustees  is not  reduced  pursuant  to
Section 5.01 or if the number of Trustees is increased pursuant to Section 5.01,
a vacancy shall occur. A resolution  certifying the existence of such vacancy by
a majority of the Regular Trustees shall be conclusive evidence of the existence
of such  vacancy.  The  vacancy  shall be  filled  with a Trustee  appointed  in
accordance with the requirements of this Article 5.

         SECTION 5.04. Effect of Vacancies. The death, resignation,  retirement,
removal,  bankruptcy,  dissolution,  liquidation,  incompetence or incapacity to
perform the duties of a Trustee,  or any one of them, shall not operate to annul
the Trust.  Whenever a vacancy in the  number of Regular  Trustees  shall  occur
until such vacancy is filled as provided in this Article 5, the Regular Trustees
in office,  regardless of their number, shall have all the powers granted to the
Regular  Trustees and shall  discharge  all the duties  imposed upon the Regular
Trustees by this Declaration.

         SECTION 5.05. Meetings.  Meetings of the Regular Trustees shall be held
from time to time upon the call of any Trustee.  Regular meetings of the Regular
Trustees  may be held at a time and place  fixed by  resolution  of the  Regular
Trustees.  Notice of any in-person meeting of the Regular Trustees shall be hand
delivered or otherwise delivered in writing (including by facsimile, with a hard
copy by overnight courier) not less than 48 hours before such meeting. Notice of
any telephonic meeting of the Regular Trustees or any committee thereof shall be
hand delivered or otherwise delivered in writing (including by facsimile, with a
hard copy by  overnight  courier)  not less than 24 hours  before such  meeting.
Notices  shall  contain a brief  statement  of the time,  place and  anticipated
purposes of the meeting.  The presence  (whether in person or by telephone) of a
Regular Trustee at a meeting shall constitute a waiver of notice of such meeting
except  where a Regular  Trustee  attends a meeting for the  express  purpose of
objecting to the  transaction of any activity on the ground that the meeting has
not  been  lawfully  called  or  convened.  Unless  provided  otherwise  in this
Declaration,  any action of the  Regular  Trustees  may be taken at a meeting by
vote of a majority  of the  Regular  Trustees  present  (whether in person or by
telephone)  and eligible to vote with respect to such  matter;  provided  that a
Quorum is present,  or without a meeting by the unanimous written consent of the
Regular Trustees.

         SECTION  5.06.  Delegation  of Power.  (a) Any Regular  Trustee may, by
power of attorney  consistent with applicable law, delegate to any other natural
person  over the age of 21 his or her power for the  purpose  of  executing  any
registration  statement or amendment thereto or other document or schedule filed
with the Commission or making any other governmental filing.

         (b) The Regular Trustees shall have power to delegate from time to time
to such of their number or to officers of the Trust the doing of such things and
the execution of such  instruments  either in the name of the Trust or the names
of the Regular Trustees or otherwise as the Regular Trustees may deem expedient,
to the extent such delegation is not prohibited by applicable law or contrary to
the provisions of the Trust, as set forth herein.

                                  DISTRIBUTIONS

         SECTION   6.01.   Distributions.   Holders   shall   receive   periodic
distributions,  redemption payments and liquidation  distributions in accordance
with the applicable terms of the relevant Holder's Securities ("Distributions").
Distributions  shall be made to the Holders of Preferred  Securities  and Common
Securities  in  accordance  with the  terms of the  Securities  as set  forth in
Exhibits  B and C hereto.  If and to the  extent  that AES  makes a  payment  of
interest (including Compounded Interest (as defined in the Indenture)),  premium
and principal on the Debentures held by the Property  Trustee (the amount of any
such  payment  being a "Payment  Amount"),  the  Property  Trustee  shall and is
directed to promptly  make a  Distribution  of the Payment  Amount to Holders in
accordance  with the terms of the  Securities  as set forth in  Exhibits B and C
hereto.


                                    ARTICLE 7
                             ISSUANCE OF SECURITIES

         SECTION 7.01. General Provisions Regarding Securities.  (a) The Regular
Trustees shall issue on behalf of the Trust  securities  representing  undivided
beneficial  interests  in the  assets of the Trust in  accordance  with  Section
7.01(b) and for the consideration specified in Section 3.03.

         (b) The Regular  Trustees  shall issue on behalf of the Trust one class
of  preferred  securities  representing  undivided  beneficial  interests in the
assets  of the  Trust  having  such  terms as are set  forth in  Exhibit  B (the
"Preferred Securities") which terms are incorporated by reference in, and made a
part of, this Declaration as if specifically set forth herein,  and one class of
common securities  representing  undivided beneficial interests in the assets of
the  Trust  having  such  terms  as are set  forth  in  Exhibit  C (the  "Common
Securities")  which terms are  incorporated by reference in, and made a part of,
this Declaration as if specifically set forth herein.

The Trust shall have no securities or other interests in the assets of the Trust
other than the Preferred Securities and the Common Securities.

         (c) The  Certificates  shall be  signed  on  behalf of the Trust by the
Regular  Trustees (or if there are more than two Regular  Trustees by any two of
the Regular Trustees). Such signatures may be the manual or facsimile signatures
of the  present or any future  Regular  Trustee.  Typographical  and other minor
errors or  defects  in any such  reproduction  of any such  signature  shall not
affect the validity of any Certificate. In case any Regular Trustee of the Trust
who shall have signed any of the  Certificates  shall  cease to be such  Regular
Trustee before the  Certificate so signed shall be delivered by the Trust,  such
Certificate  nevertheless  may be delivered as though the person who signed such
Certificate had not ceased to be such Regular  Trustee;  and any Certificate may
be signed on behalf of the Trust by such  persons  as, at the actual date of the
execution  of such  Certificate,  shall be the  Regular  Trustees  of the Trust,
although at the date of the execution and delivery of the  Declaration  any such
person  was  not  such  a  Regular  Trustee.   Certificates  shall  be  printed,
lithographed or engraved or may be produced in any other manner as is reasonably
acceptable to the Regular Trustees, as evidenced by their execution thereof, and
may have such letters,  numbers or other marks of  identification or designation
and such legends or endorsements as the Regular  Trustees may deem  appropriate,
or as may be required to comply with any law or with any rule or regulation made
pursuant  thereto or with any rule or regulation of any stock  exchange on which
Securities  may be listed,  or to conform to usage.  Pending the  preparation of
definitive Certificates, the Regular Trustees on behalf of the Trust may execute
temporary Certificates (printed,  lithographed or typewritten), in substantially
the form of the definitive  Certificates  in lieu of which they are issued,  but
with  such  omissions,  insertions  and  variations  as may be  appropriate  for
temporary  Certificates,  all as may be determined by the Regular Trustees. Each
temporary Certificate shall be executed by the Regular Trustees on behalf of the
Trust upon the same conditions and in  substantially  the same manner,  and with
like effect, as definitive Certificates.  Without unnecessary delay, the Regular
Trustees on behalf of the Trust will execute and furnish definitive Certificates
and  thereupon  any or all  temporary  Certificates  may be  surrendered  to the
transfer  agent  and  registrar  in  exchange  therefor  (without  charge to the
Holders).  Each  Certificate  whether in temporary or  definitive  form shall be
countersigned by the manual or facsimile signature of an authorized signatory of
the Person  acting as registrar  and transfer  agent for the  Securities,  which
shall initially be the Property Trustee.

         (d) The  consideration  received  by the Trust for the  issuance of the
Securities shall constitute a contribution to the capital of the Trust and shall
not constitute a loan to the Trust.

         (e) Upon issuance of the  Securities  as provided in this  Declaration,
the  Securities so issued shall be deemed to be validly  issued,  fully paid and
non-assessable.

         (f) Every  Person,  by virtue of having  become a Holder or a Preferred
Security  Beneficial  Owner in  accordance  with the terms of this  Declaration,
shall be deemed to have expressly assented and agreed to the terms of, and shall
be bound by this Declaration.

         (g) Upon issuance of the  Securities  as provided in this  Declaration,
the  Regular  Trustees  on  behalf  of the  Trust  shall  return  to AES the $10
constituting initial trust assets as set forth in the Original Declaration.

         SECTION 7.02.  Conversion  Agent. The Trust shall maintain an office or
agency where Preferred  Securities may be presented for conversion  ("Conversion
Agent").  The Trust may appoint the Conversion Agent and may appoint one or more
additional  Conversion  Agents in such other locations as it may determine.  The
term "Conversion Agent" includes any additional  Conversion Agent. The Trust may
change any  Conversion  Agent without prior notice to any Holders.  If the Trust
fails to appoint or maintain  another entity as Conversion  Agent,  the Property
Trustee  will  act as  such.  The  Trust  or any of its  Affiliates  may  act as
Conversion  Agent.  The Trust  shall  act as  Conversion  Agent  for the  Common
Securities. The Conversion Agent shall be entitled to the rights and protections
extended to the Property Trustee when acting in such capacity.

         The Property Trustee is hereby initially  appointed as Conversion Agent
for the Preferred Securities.

                              TERMINATION OF TRUST

         SECTION 8.01.  Termination  of Trust.  This  Declaration  and the Trust
shall terminate and be of no further force or effect when:

         (a) all of the Securities shall have been called for redemption and the
amounts necessary for redemption  thereof shall have been paid to the Holders of
Securities in accordance with the terms of the Securities; or

         (b) all of the Debentures shall have been distributed to the Holders of
Securities in exchange for all of the Securities in accordance with the terms of
the Securities; or



                                       35
<PAGE>


         (c)  upon the  expiration  of the  term of the  Trust  as set  forth in
Section 3.16; or,

         (d)  upon  the  distribution  of  the  Sponsor's  common  stock  to all
Securities Holders upon conversion of all outstanding Preferred Securities,

and a certificate of cancellation is filed by the Trustees with the Secretary of
State of the State of Delaware. The Trustees shall so file such a certificate as
soon as practicable after the occurrence of an event referred to in this Section
8.01.

         The  provisions  of Sections 3.12 and 4.02 and Article 10 shall survive
the termination of the Trust.


                                    ARTICLE 9

                              TRANSFER OF INTERESTS

         SECTION  9.01.  Transfer  of  Securities.  (a)  Securities  may only be
transferred,  in whole or in part, in accordance  with the terms and  conditions
set  forth in this  Declaration.  Any  transfer  or  purported  transfer  of any
Security not made in accordance with this Declaration shall be null and void.

          (b) Subject to this Article 9,  Preferred  Securities  shall be freely
transferable.

          (c)  Subject  to this  Article 9, AES and any  Related  Party may only
transfer  Common  Securities to AES or a Related  Party;  provided that any such
transfer  shall be  subject  to the  condition  that the  transferor  shall have
obtained (1) either a ruling from the Internal Revenue Service or an unqualified
written  opinion  addressed  to the  Trust  and  delivered  to the  Trustees  of
nationally recognized independent tax counsel experienced in such matters to the
effect that such  transfer will not (i) cause the Trust to be treated as issuing
a class  of  interests  in the  Trust  differing  from the  class  of  interests
represented by the Common  Securities  originally  issued to AES, (ii) result in
the Trust  acquiring  or  disposing  of, or being  deemed  to have  acquired  or
disposed  of, an asset,  or (iii)  result in or cause the Trust to be treated as
anything  other  than a grantor  trust for  United  States  federal  income  tax
purposes  and (2) an  unqualified  written  opinion  addressed  to the Trust and
delivered  to  the  Trustees  of a  nationally  recognized  independent  counsel
experienced in such matters that such transfer will not cause the Trust to be an
Investment Company or controlled by an Investment Company.

         (d) Each  Security  that  bears or is  required  to bear the legend set
forth in this Section 9.01(d) (a "Restricted  Security") shall be subject to the
restrictions  on  transfer  provided  in the  legend  set forth in this  Section
9.01(d),  unless such  restrictions  on transfer  shall be waived by the written
consent of the Regular Trustees,  and the Holder of each Restricted Security, by
such   securityholder's   acceptance  thereof,   agrees  to  be  bound  by  such
restrictions on transfer.  As used in this Section 9.01(d),  the term "transfer"
encompasses any sale,  pledge,  transfer or other  disposition of any Restricted
Security.

         Prior to the Transfer  Restriction  Termination  Date,  the 144A Global
Security,  Temporary  Regulation S Global  Security,  each Definitive  Preferred
Security and any  certificate  evidencing  Common  Stock issued upon  conversion
thereof  shall  bear a  legend  in  substantially  the  following  form,  unless
otherwise  agreed by the Regular  Trustees  (with written  notice thereof to the
Indenture Trustee):

              THIS SECURITY HAS NOT BEEN  REGISTERED  UNDER THE U.S.  SECURITIES
              ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,  ACCORDINGLY,
              MAY NOT BE  OFFERED OR SOLD  EXCEPT AS SET FORTH IN THE  FOLLOWING
              SENTENCE.  BY ITS  ACQUISITION  HEREOF,  THE HOLDER (1) REPRESENTS
              THAT (A) IT IS A  "QUALIFIED  INSTITUTIONAL  BUYER" (AS DEFINED IN
              RULE 144A UNDER THE SECURITIES  ACT),  (B) IT IS AN  INSTITUTIONAL
              "ACCREDITED INVESTOR" IN RULE 501(a)(1), (2), (3) OR (7) UNDER THE
              SECURITIES ACT (AN "INSTITUTIONAL  ACCREDITED INVESTOR")),  OR (C)
              IT IS NOT A U.S.  PERSON  AND IS  ACQUIRING  THIS  SECURITY  IN AN
              OFFSHORE  TRANSACTION,  (2)  AGREES  THAT IT WILL NOT PRIOR TO THE
              EXPIRATION  OF THE  HOLDING  PERIOD  APPLICABLE  TO  SALES  OF THE
              SECURITY  EVIDENCED  HEREBY UNDER RULE 144(k) UNDER THE SECURITIES
              ACT (OR ANY  SUCCESSOR  PROVISION),  RESELL OR OTHERWISE  TRANSFER
              THIS SECURITY  EXCEPT (A) TO AES OR ANY  SUBSIDIARY  THEREOF,  (B)
              INSIDE THE UNITED  STATES TO A  QUALIFIED  INSTITUTIONAL  BUYER IN
              COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) INSIDE THE
              UNITED STATES TO AN INSTITUTIONAL ACCREDITED INVESTOR THAT, BEFORE
              SUCH TRANSFER

              REPRESENTATIONS  AND AGREEMENTS  RELATING TO THE  RESTRICTIONS  ON
              TRANSFER  OF THIS  SECURITY  (THE  FORM  OF  WHICH  LETTER  CAN BE
              OBTAINED  FROM THE TRUSTEE) AND IF SUCH  TRANSFER IS IN RESPECT OF
              AN AGGREGATE PRINCIPAL AMOUNT OF SECURITIES LESS THAN $250,000, AN
              OPINION OF COUNSEL  ACCEPTABLE  TO THE TRUST THAT SUCH TRANSFER IS
              IN  COMPLIANCE  WITH THE  SECURITIES  ACT,  (D) OUTSIDE THE UNITED
              STATES IN AN  OFFSHORE  TRANSACTION  IN  COMPLIANCE  WITH RULE 904
              UNDER THE  SECURITIES  ACT,  (E)  PURSUANT TO THE  EXEMPTION  FROM
              REGISTRATION  PROVIDED  BY RULE 144 UNDER THE  SECURITIES  ACT (IF
              AVAILABLE) OR (F) PURSUANT TO AN EFFECTIVE  REGISTRATION STATEMENT
              UNDER THE  SECURITIES  ACT AND (3) AGREES THAT IT WILL  DELIVER TO
              EACH  PERSON  TO  WHOM  THIS  SECURITY  IS  TRANSFERRED  A  NOTICE
              SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY
              TRANSFER  OF THIS  SECURITY  PRIOR TO THE  EXPIRATION  DATE OF THE
              HOLDING  PERIOD  APPLICABLE  TO  SALES OF THE  SECURITY  EVIDENCED
              HEREBY  UNDER  RULE  144(k)  UNDER  THE  SECURITIES  ACT  (OR  ANY
              SUCCESSOR  PROVISION),  THE TRANSFEROR  MUST CHECK THE APPROPRIATE
              BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH
              TRANSFER AND SUBMIT THIS CERTIFICATE TO THE PROPERTY  TRUSTEE.  IF
              THE PROPOSED TRANSFEREE IS AN INSTITUTIONAL  ACCREDITED  INVESTOR,
              THE TRANSFEROR MUST,  BEFORE SUCH TRANSFER,  FURNISH TO THE ISSUER
              SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS IT MAY
              REASONABLY  REQUIRE TO CONFIRM  THAT SUCH  TRANSFER  IS BEING MADE
              PURSUANT TO AN EXEMPTION FROM OR IN A TRANSACTION  NOT SUBJECT TO,
              THE  REGISTRATION  REQUIREMENTS  OF THE  SECURITIES  ACT.  AS USED
              HEREIN,  THE TERMS



                                       38
<PAGE>


              "OFFSHORE TRANSACTION", "UNITED STATES" AND "U.S. PERSON" HAVE THE
              MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

         Following the Transfer  Restriction  Termination  Date or the sale of a
Security or Common Stock for which a Security has been exchanged  pursuant to an
effective registration statement or Rule 144, any Security or security issued in
exchange or  substitution  therefor  (other than (i) Securities  acquired by the
Sponsor or any  Affiliate  and (ii) Common Stock issued upon the  conversion  or
exchange of any Security  described  in clause (i) above) may upon  surrender of
such  Security  for  exchange to any  Regular  Trustee on behalf of the Trust in
accordance with the provisions of this Section  9.01(d),  be exchanged for a new
Security or Securities,  of like tenor and aggregate  liquidation amount,  which
shall not bear the restrictive legend required by this Section 9.01(d).

         SECTION 9.02.  Transfer of  Certificates.  The Regular  Trustees  shall
provide for the  registration of Certificates  and of transfers of Certificates,
which will be effected without charge but only upon payment (with such indemnity
as the Regular  Trustees may require) in respect of any tax or other  government
charges which may be imposed in relation to it. Upon surrender for  registration
of transfer of any Certificate, the Regular Trustees shall cause one or more new
Certificates  to  be  issued  in  the  name  of  the  designated  transferee  or
transferees. Every Certificate surrendered for registration of transfer shall be
accompanied  by a written  instrument  of transfer in form  satisfactory  to the
Regular  Trustees  duly  executed by the Holder or such  Holder's  attorney duly
authorized in writing. Each Certificate surrendered for registration of transfer
shall be canceled by the Regular  Trustees.  A transferee of a Certificate shall
be entitled to the rights and subject to the  obligations of a Holder  hereunder
upon the  receipt  by such  transferee  of a  Certificate.  By  acceptance  of a
Certificate,  each transferee shall be deemed to have agreed to be bound by this
Declaration.

         SECTION  9.03.  Deemed  Security  Holders.  The  Trustees may treat the
Person  in whose  name any  Certificate  shall be  registered  on the  books and
records  of  the  Trust  as the  sole  holder  of  such  Certificate  and of the
Securities   represented   by  such   Certificate   for  purposes  of  receiving
Distributions and for all other purposes whatsoever and, accordingly,  shall not
be bound to  recognize  any  equitable  or other  claim to or  interest  in such
Certificate or in the Securities  represented by such Certificate on the part of
any  Person,  whether  or not the  Trustees  shall have  actual or other  notice
thereof.

         SECTION 9.04. Book Entry  Interests.  (a) Except as provided in Section
9.07 and unless  otherwise  specified in the terms of the Preferred  Securities,
the Preferred Securities Certificates, on original issuance (including Preferred
Securities,  if any,  issued on the Option Closing Date pursuant to the exercise
of the overallotment option set forth in the Purchase Agreement), will be issued
in  the  form  of one or  more,  fully  registered,  global  Preferred  Security
Certificates (each a "Global Certificate"),  to be delivered to DTC, the initial
Clearing Agency, by, or on behalf of, the Trust. Such Global  Certificates shall
initially  be  registered  on the books and  records of the Trust in the name of
Cede & Co., the nominee of DTC, and no Preferred Security  Beneficial Owner will
receive a definitive Preferred Security Certificate  representing such Preferred
Security  Beneficial  Owner's interests in such Global  Certificates,  except as
provided in Section 9.07.

         (b) Preferred  Securities that upon initial  issuance are  beneficially
owned by QIBs may,  at the option of the Trust,  be  represented  by one or more
Global  Certificates (a "144A Global Security"),  and Preferred  Securities that
upon initial  issuance are  beneficially  owned by Non-U.S.  Persons may, at the
option of the  Trust,  be  represented  by one or more  Global  Certificates  (a
"Temporary  Regulation S Global Security").  At any time on or after December 9,
1997 (the "Regulation S Securities Exchange Date"), one or more permanent Global
Certificates  without the legend set forth in Section  9.01(d)  (the  "Permanent
Regulation S Global  Security",  and together  with the  Temporary  Regulation S
Global Security,  the "Regulation S Global  Securities") shall be deposited with
the Clearing Agency, and the Property Trustee shall make endorsements reflecting
a decrease in the principal amount of the Temporary Regulation S Global Security
in an amount equal to the  principal  amount of the  beneficial  interest in the
Temporary  Regulation S Global Security  transferred.  Transfers of interests in
the Preferred  Securities  between any 144A Global Security and any Regulation S
Global  Security will be made in accordance with the standing  instructions  and
procedures of the Clearing  Agency and its  participants.  The Property  Trustee
shall make  appropriate  endorsements  to reflect  increases or decreases in the
amount  of such  Preferred  Securities  in  global  form  to  reflect  any  such
transfers.

         Except as provided below,  beneficial owners of a Preferred Security in
global  form shall not be  entitled  to have  certificates  registered  in their
names,  will  not  receive  or be  entitled  to  receive  physical  delivery  of
certificates  in  definitive  form and will not be  considered  Holders  of such
Preferred Security in global form.

         Any transfer of a beneficial interest in a Preferred Security in global
form which cannot be effected through book-entry  settlement must be effected by
the  delivery  to the  transferee  (or its  nominee) of a  Definitive  Preferred
Security Certificate or Definitive Preferred Security Certificates registered in
the name of




                                       40
<PAGE>


the transferee (or its nominee) on the books maintained by the Property Trustee.
With  respect  to any  such  transfer,  the  Property  Trustee  will  cause,  in
accordance with the standing instructions and procedures of the Clearing Agency,
the aggregate  principal amount at maturity of the Preferred  Security in global
form to be reduced and,  following such reduction,  the Sponsor will execute and
the Property  Trustee will  authenticate  and make available for delivery to the
transferee  (or such  transferee's  nominee,  as the case may be),  a  Preferred
Security or Securities in the appropriate aggregate principal amount at maturity
in the name of such  transferee  (or its nominee)  and bearing such  restrictive
legends as may be required by this Declaration of Trust.

         (c) So long as the  Preferred  Securities  are eligible for  book-entry
settlement  and to the  extent  Preferred  Securities  held by QIBs or  Non-U.S.
Persons,  as the case may be,  are held in a global  form,  or unless  otherwise
required by law, upon any transfer of a Definitive  Preferred  Security to a QIB
in  accordance  with  Rule  144A or to a  Non-U.S.  Person  in  accordance  with
Regulation S, unless otherwise requested by the transferor,  and upon receipt of
the Definitive  Preferred  Security  Certificate being so transferred,  together
with a  certification  from the  transferor  that the  transfer is being made in
compliance with Rule 144A or Regulation S, as the case may be (or other evidence
satisfactory  to the  Property  Trustee on behalf of the  Trust),  the  Property
Trustee on behalf of the Trust  shall  make an  endorsement  on any 144A  Global
Security or any Regulation S Global Security,  as the case may be, to reflect an
increase  in the  number of  Preferred  Securities  represented  by such  Global
Certificate,  and the Property  Trustee on behalf of the Trust shall cancel such
Definitive  Preferred Security in accordance with the standing  instructions and
procedures  of  the  Clearing  Agency,   the  number  of  Preferred   Securities
represented  by  such  Preferred   Security  in  global  form  to  be  increased
accordingly; provided that no Definitive Preferred Security, or portion thereof,
in respect of which the Trust or an Affiliate  of the Trust held any  beneficial
interest shall be included in such Preferred  Security in global form until such
Definitive Preferred Security is freely tradable in accordance with Rule 144(k);
provided  further that the Trust shall issue Preferred  Securities in definitive
form upon any transfer of a  beneficial  interest in the  Preferred  Security in
global form to the Sponsor or any Affiliate of the Sponsor.

         (d) Any Global Certificate may be endorsed with or have incorporated in
the text thereof such legends or recitals or changes not  inconsistent  with the
provisions of this Declaration as may be required by the Clearing Agency, by any
national  securities  exchange  or by the  National  Association  of  Securities
Dealers,  Inc. in order for the  Preferred  Securities  to be  tradeable  on the
PORTAL Market or as may be required for the Preferred Securities to be tradeable
on any other market developed for trading of securities pursuant to Rule 144A or
required to comply with any applicable law or any regulation  thereunder or with
the rules and





                                       41

regulations of any securities  exchange upon which the Preferred  Securities may
be listed or traded or to conform  with any usage with  respect  thereto,  or to
indicate  any  special  limitations  or  restrictions  to which  any  particular
Preferred Securities are subject. Unless and until definitive,  fully registered
Preferred   Security    Certificates   (the   "Definitive   Preferred   Security
Certificates")  have been issued to the  Preferred  Security  Beneficial  Owners
pursuant to Section 9.07:

              (i) the provisions of this Section 9.04 shall be in full force and
         effect;

              (ii) the Trust and the Trustees shall be entitled to deal with the
         Clearing  Agency for all purposes of this  Declaration  (including  the
         payment of  Distributions  on the  Global  Certificates  and  receiving
         approvals,  votes or consents hereunder) as the Holder of the Preferred
         Securities and the sole holder of the Global  Certificates  and, except
         as set  forth  herein  or in Rule 3a-7  with  respect  to the  Property
         Trustee,  shall have no obligation to the Preferred Security Beneficial
         Owners;  provided,  that solely for the purposes of determining whether
         the Holders of the requisite amount of Preferred  Securities have voted
         on any matter provided for in this  Declaration,  so long as definitive
         Preferred  Security  Certificates  have not been  issued  (pursuant  to
         Section 9.07 hereof),  the Trustees may conclusively rely on, and shall
         be protected in relying on, any written instrument  (including a proxy)
         delivered  to the  Trustees by the Clearing  Agency  setting  forth the
         Preferred  Security  Beneficial Owners' votes or assigning the right to
         vote on any matter to any other Persons either in whole or in part;

              (iii) to the  extent  that the  provisions  of this  Section  9.04
         conflict with any other provisions of this Declaration,  the provisions
         of this Section 9.04 shall control; and

              (iv) the rights of the Preferred Security  Beneficial Owners shall
         be exercised  only through the Clearing  Agency and shall be limited to
         those established by law and agreements between such Preferred Security
         Beneficial  Owners and the Clearing  Agency and/or the Clearing  Agency
         Participants.  DTC will make book entry  transfers  among the  Clearing
         Agency  Participants and receive and transmit payments of Distributions
         on the Global Certificates to such Clearing Agency Participants.

         SECTION 9.05. Notices to Holders of Certificates.  Whenever a notice or
other  communication  to  the  Holders  is  required  to  be  given  under  this
Declaration,  unless and until Definitive Preferred Security  Certificates shall
have been issued pursuant to Section 9.07, the relevant  Trustees shall give all
such  notices  and




                                       42
<PAGE>


communications, specified herein to be given to Preferred Securities Holders, to
the Clearing  Agency and,  with respect to any  Preferred  Security  Certificate
registered in the name of a Clearing Agency or the nominee of a Clearing Agency,
the Trustees  shall,  except as set forth herein or in Rule 3a-7 with respect to
the Property  Trustee,  have no notice  obligations  to the  Preferred  Security
Beneficial Owners.

         SECTION 9.06. Appointment of Successor Clearing Agency. If any Clearing
Agency elects to discontinue its services as securities  depository with respect
to the Preferred Securities, the Regular Trustees may, in their sole discretion,
appoint a successor Clearing Agency with respect to the Preferred Securities.

         SECTION 9.07. Definitive Preferred Securities Certificates.  (a) If (i)
a Clearing  Agency elects to discontinue  its services as securities  depository
with respect to the Preferred  Securities and a successor Clearing Agency is not
appointed within 90 days after such  discontinuance  pursuant to Section 9.06 or
(ii) the Regular Trustees elect after consultation with the Sponsor to terminate
the book entry system through the Clearing  Agency with respect to the Preferred
Securities,  then  (x)  Definitive  Preferred  Security  Certificates  shall  be
prepared  by the Regular  Trustees  on behalf of the Trust with  respect to such
Preferred  Securities and (y) upon surrender of the Global  Certificates  by the
Clearing Agency, accompanied by registration instructions,  the Regular Trustees
shall cause  definitive  Preferred  Security  Certificates  to be  delivered  to
Preferred Security  Beneficial Owners in accordance with the instructions of the
Clearing  Agency.  Neither  the  Trustees  nor the Trust shall be liable for any
delay indelivery of such  instructions and each of them may conclusively rely on
and shall be protected in relying on, such instructions.

         (b) Restricted  Securities that upon initial  issuance are beneficially
owned by, or are subsequently transferred to, Institutional Accredited Investors
that  are  neither  QIBs nor  Non-U.S.  Persons  will be  issued  as  Definitive
Preferred  Security  Certificates  and  may  not  be  represented  by  a  Global
Certificate.  Preferred  Securities that upon initial  issuance are beneficially
owned by Persons that are Non-U.S.  Persons may, at the option of the Trust,  be
issued as  Definitive  Preferred  Security  Certificates.  Definitive  Preferred
Security  Certificates  issued  in  exchange  for all or a part  of a  Preferred
Security in global form shall be registered in such names and in such authorized
denominations as the Clearing Agency,  pursuant to instructions  from its direct
or indirect participants or otherwise, shall instruct the Property Trustee. Upon
execution and  authentication,  the Property  Trustee  shall make  available for
delivery such Definitive Preferred Security  Certificates to the person in whose
name such Definitive Preferred Security  Certificates are so registered.  In the
case of transfers to Institutional




                                       43
<PAGE>


Accredited Investors,  the Property Trustee shall make appropriate  endorsements
to reflect decreases in the amount of the applicable Global Certificate.

         SECTION 9.08. Mutilated, Destroyed, Lost or Stolen Certificates. If (a)
any mutilated  Certificates should be surrendered to the Regular Trustees, or if
the  Regular  Trustees  shall  receive  evidence  to their  satisfaction  of the
destruction,  loss or theft of any Certificate; and (b) there shall be delivered
to the Regular Trustees such security or indemnity as may be required by them to
keep each of them harmless,  then in the absence of notice that such Certificate
shall have been acquired by a bona fide purchaser,  any two Regular  Trustees on
behalf of the Trust shall execute and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
denomination.  In connection with the issuance of any new Certificate under this
Section 9.08,  the Regular  Trustees may require the payment of a sum sufficient
to cover any tax or other governmental  charge that may be imposed in connection
therewith.  Any  duplicate  Certificate  issued  pursuant to this section  shall
constitute  conclusive  evidence  of  an  ownership  interest  in  the  relevant
Securities,  as if  originally  issued,  whether  or not  the  lost,  stolen  or
destroyed Certificate shall be found at any time.


                                   ARTICLE 10

Trust and in a manner such Indemnified  Person reasonably  believed to be within
the  scope  of the  authority  conferred  on  such  Indemnified  Person  by this
Declaration or by law, except that an Indemnified Person shall be liable for any
such loss, damage or claim incurred by reason of such Indemnified Person's gross
negligence  (but,  in the case of the  Property  Trustee,  subject  to the Trust
Indenture Act) or willful misconduct with respect to such acts or omissions.

          (b) An Indemnified  Person shall be fully protected in relying in good
faith upon the records of the Trust and upon such information, opinions, reports
or statements presented to the Trust by any Person as to matters the Indemnified
Person reasonably believes are within such other Person's professional or expert
competence and who has been selected with reasonable care by or on behalf of the
Trust,  including information,  opinions,  reports or statements as to the value
and  amount of the  assets,  liabilities,  profits,  losses  or any other  facts
pertinent  to the



                                       44
<PAGE>

existence and amount of assets from which Distributions to Holders of Securities
might properly be paid.

         (c) Pursuant to ss.  3803(a) of the Business  Trust Act, the Holders of
Securities,  in their  capacities  as  Holders,  shall be  entitled  to the same
limitation of liability that is extended to stockholders of private corporations
for profit organized under the General Corporation Law of the State of Delaware.

         SECTION 10.02. Indemnification.  (a) To the fullest extent permitted by
applicable law, the Sponsor shall  indemnify and hold harmless each  Indemnified

by such  Indemnified  Person by reason of gross  negligence (but, in the case of
the Property Trustee,  subject to the Trust Indenture Act) or willful misconduct
with respect to such acts or omissions.

         (b) To  the  fullest  extent  permitted  by  applicable  law,  expenses
(including legal fees) incurred by an Indemnified Person in defending any claim,
demand,  action, suit or proceeding shall, from time to time, be advanced by the
Sponsor prior to the final disposition of such claim,  demand,  action,  suit or
proceeding  upon receipt by the Sponsor of an undertaking by or on behalf of the
Indemnified  Person  to repay  such  amount if it shall be  determined  that the
Indemnified  Person is not entitled to be  indemnified  as authorized in Section
10.02(a).

         (c) The provisions of this Section 10.02 shall survive the  termination
of this Declaration or the resignation or removal of any Trustee.

         SECTION 10.03. Outside Business. The Sponsor and any Trustee may engage
in or  possess  an  interest  in  other  business  ventures  of  any  nature  or
description, independently or with others, similar or dissimilar to the business
of the Trust,  and the Trust and the Holders of Securities  shall have no rights
by virtue of this Declaration in and to such independent  ventures or the income
or profits  derived  therefrom,  and the  pursuit of any such  venture,  even if
competitive  with the  business  of the Trust,  shall not be deemed  wrongful or
improper.  Neither the Sponsor nor any Trustee shall be obligated to present any
particular investment or other opportunity to the Trust even if such opportunity
is of a character that, if presented to the Trust,  could be taken by the Trust,
and the Sponsor or any Trustee  shall have the right to take for its own account





                                       45

(individually  or as a partner or  fiduciary) or to recommend to others any such
particular  investment  or other  opportunity.  Any  Trustee  may  engage  or be
interested  in any  financial  or  other  transaction  with the  Sponsor  or any
Affiliate of the Sponsor or may act as depository for,  trustee or agent for, or
act on any committee or body of holders of,  securities or other  obligations of
the Sponsor or its Affiliates.

         SECTION  11.01.  Fiscal Year.  The fiscal year  ("Fiscal  Year") of the
Trust shall be the calendar year, or such other year as is required by the Code.

         SECTION 11.02.  Certain Accounting Matters. (a) At all times during the
existence of the Trust,  the Regular  Trustees  shall keep, or cause to be kept,
full books of account, records and supporting documents,  which shall reflect in
reasonable detail,  each transaction of the Trust. The books of account shall be
maintained on the accrual  method of  accounting,  in accordance  with generally
accepted accounting  principles,  consistently  applied. The Trust shall use the
accrual method of accounting for United States federal income tax purposes.  The
books and records of the Trust,  together with a copy of this  Declaration and a
certified copy of the Certificate of Trust, or any amendment  thereto,  shall at
all times be maintained  at the principal  office of the Trust and shall be open
for  inspection  for  any  examination  by any  Holder  or its  duly  authorized

Holder of Securities,  an annual United States  federal  income tax  information
statement,  on such form as is required by the Code, containing such information
with regard to the Securities held by each Holder as is required by the Code and
the Treasury  Regulations.  Notwithstanding  any right under the Code to deliver
any such  statement  at a later date,  the Regular  Trustees  shall  endeavor to
deliver all such statements  within 30 days after the end of each Fiscal Year of
the Trust.

          (c) The Regular Trustees shall cause to be prepared and filed with the
appropriate taxing authority, an annual United States federal income tax return,

         SECTION  11.03.  Banking.  The Trust  shall  maintain  one or more bank
accounts in the name and for the sole benefit of the Trust;  provided,  however,
that all  payments of funds in respect of the  Debentures  held by the  Property
Trustee shall be made  directly to the Property  Account and no other funds from
the Trust shall be deposited in the Property  Account.  The sole signatories for
such accounts shall be designated by the Regular  Trustees;  provided,  however,
that the Property  Trustee shall designate the sole signatories for the Property
Account.

         SECTION  11.04.  Withholding.  The Trust and the Trustees  shall comply
with all withholding  requirements under United States federal,  state and local
law. The Trust shall request,  and the Holders shall provide to the Trust,  such
forms  or   certificates  as  are  necessary  to  establish  an  exemption  from
withholding with respect to each Holder,  and any  representations  and forms as
shall  reasonably  be  requested  by the Trust to assist it in  determining  the
extent of, and in fulfilling, its withholding obligations.  The Trust shall file
required  forms with  applicable  jurisdictions  and,  unless an exemption  from
withholding is properly  established by a Holder,  shall remit amounts  withheld
with respect to the Holder to applicable  jurisdictions.  To the extent that the
Trust is  required to withhold  and pay over any amounts to any  authority  with
respect to distributions or allocations to any Holder, the amount withheld shall
be deemed to be a distribution  in the amount of the  withholding to the Holder.
In the event of any  claimed  overwithholding,  Holders  shall be  limited to an
action against the applicable jurisdiction. If the amount to be withheld was not
withheld from a Distribution,  the Trust may reduce subsequent  Distributions by
the amount of such withholding.

                             AMENDMENTS AND MEETINGS

         SECTION  12.01.  Amendments.  (a) Except as otherwise  provided in this
Declaration or by any applicable  terms of the Securities,  this Declaration may
be amended by, and only by, a written  instrument  executed by a majority of the
Regular Trustees;  provided,  however, that (i) no amendment to this Declaration
shall be made  unless the  Regular  Trustees  shall have  obtained  (A) either a
ruling from the Internal  Revenue  Service or a written  unqualified  opinion of
nationally recognized independent tax counsel experienced in such matters





                                       47
<PAGE>


to the effect that such  amendment will not cause the Trust to be classified for
United  States  federal  income  tax  purposes  as an  association  taxable as a
corporation  or a partnership  and to the effect that the Trust will continue to
be treated as a grantor  trust for  purposes  of United  States  federal  income
taxation  and  (B)  a  written  unqualified  opinion  of  nationally  recognized
independent  counsel  experienced  in  such  matters  to the  effect  that  such
amendment will not cause the Trust to be an Investment Company which is required
to be registered  under the Investment  Company Act, (ii) at such time after the
Trust has issued any Securities  which remain  outstanding,  any amendment which
would  adversely  affect the rights,  privileges or preferences of any Holder of
Securities may be effected only with such additional  requirements as may be set
forth in the terms of such Securities,  (iii) Section 4.02,  Section 9.01(c) and
this  Section  12.01  shall not be  amended  without  the  consent of all of the
Holders of the Securities, (iv) no amendment which adversely affects the rights,
powers and privileges of the Property  Trustee shall be made without the consent
of the Property Trustee,  (v) Article 4 shall not be amended without the consent
of the  Sponsor,  and (vi) the  rights of  Holders  of Common  Securities  under
Article 5 to  increase or  decrease  the number of, and to  appoint,  replace or
remove,  Trustees  shall not be amended  without  the  consent of each Holder of
Common Securities.

         (b)  Notwithstanding  Section  12.02(a)(ii),  this  Declaration  may be
amended  without the consent of the  Holders of the  Securities  to (i) cure any
ambiguity, (ii) correct or supplement any provision in this Declaration that may
be defective or inconsistent with any other provision of this Declaration, (iii)
to add to the covenants, restrictions or obligations of the Sponsor, and (iv) to
conform  to any  changes  in  Rule  3a-7  or any  change  in  interpretation  or
application of Rule 3a-7 by the  Commission,  which amendment does not adversely
affect the rights, preferences or privileges of the Holders.

         SECTION 12.02. Meetings of the Holders of Securities; Action by Written
Consent.  (a)  Meetings of the Holders of  Preferred  Securities  and/or  Common
Securities may be called at any time by the Regular  Trustees (or as provided in
the terms of the  Securities) to consider and act on any matter on which Holders
of such  class  of  Securities  are  entitled  to act  under  the  terms of this
Declaration,  the terms of the  Securities or the rules of any stock exchange on
which the Preferred  Securities are listed or admitted for trading.  The Regular
Trustees  shall  call a meeting of Holders  of  Preferred  Securities  or Common
Securities,  if  directed  to do so by  Holders  of at least 10% in  liquidation
amount of such class of Securities.  Such direction shall be given by delivering
to the Regular  Trustees one or more calls in a writing stating that the signing
Holders of  Securities  wish to call a meeting  and  indicating  the  general or
specific  purpose  for  which  the  meeting  is to be  called.  Any  Holders  of
Securities  calling a meeting shall specify in writing the Certificates  held by
the Holders of Securities  exercising the right to call a meeting and only those
specified  Certificates shall be counted for purposes of determining whether the
required  percentage set forth in the second sentence of this paragraph has been
met.




                                       48

         (b)  Except  to the  extent  otherwise  provided  in the  terms  of the
Securities,  the  following  provision  shall  apply to  meetings  of Holders of
Securities:

              (i) Notice of any such  meeting  shall be given by mail to all the
         Holders of  Securities  having a right to vote  thereat not less than 7
         days nor more than 60 days prior to the date of such meeting.  Whenever
         a vote,  consent or approval of the Holders of  Securities is permitted
         or required  under this  Declaration or the rules of any stock exchange
         on which the Preferred  Securities  are listed or admitted for trading,
         such vote, consent or approval may be given at a meeting of the Holders
         of Securities. Any action that may be taken at a meeting of the Holders
         of  Securities  may be taken  without a meeting if a consent in writing
         setting  forth the action so taken is signed by  Holders of  Securities
         owning  not less  than the  minimum  aggregate  liquidation  amount  of
         Securities  that would be necessary to authorize or take such action at
         a meeting  at which all  Holders of  Securities  having a right to vote
         thereon were present and voting.  Prompt notice of the taking of action
         without a meeting shall be given to the Holders of Securities  entitled
         to vote who have not  consented  in writing.  The Regular  Trustees may
         specify that any written ballot  submitted to the Holders of Securities
         for the  purpose  of taking  any  action  without  a  meeting  shall be
         returned  to the  Trust  within  the  time  specified  by  the  Regular
         Trustees.

              (ii) Each Holder of a Security may authorize any Person to act for
         it by proxy on all  matters in which a Holder of a Security is entitled
         to participate,  including waiving notice of any meeting,  or voting or
         participating  at  a  meeting.  No  proxy  shall  be  valid  after  the
         expiration of 11 months from the date thereof unless otherwise provided
         in the proxy.  Every proxy shall be  revocable  at the  pleasure of the
         Holder of the  Security  executing  it.  Except as  otherwise  provided
         herein or in the terms of the Securities,  all matters  relating to the
         giving,  voting or validity of proxies shall be governed by the General
         Corporation  Law of the State of  Delaware  relating  to  proxies,  and
         judicial  interpretations  thereunder,  as if the Trust were a Delaware
         corporation  and the Holders of the Securities  were  stockholders of a
         Delaware corporation.

              (iii) Each  meeting  of the  Holders  of the  Securities  shall be
         conducted  by the  Regular  Trustees  or by such other  Person that the
         Regular Trustees may designate.

              (iv) Unless  otherwise  provided in the Business  Trust Act,  this
         Declaration  or the rules of any stock  exchange on which the Preferred




                                       49
<PAGE>


         Securities  are then  listed  or  admitted  for  trading,  the  Regular
         Trustees,   in  their  sole  discretion,   shall  establish  all  other
         provisions  relating to meetings  of Holders of  Securities,  including
         notice of the time, place or purpose of any meeting at which any matter
         is to be voted on by any  Holders  of  Securities,  waiver  of any such
         notice,  action by consent without a meeting,  the  establishment  of a
         record date, quorum  requirements,  voting in person or by proxy or any
         other matter with respect to the exercise of any such right to vote.

time of the  Successor  Property  Trustee's  acceptance  of its  appointment  as
Property Trustee that:

              (i) The Property  Trustee is a national  banking  association or a
         banking corporation with trust powers, duly organized, validly existing
         and in good standing under the laws of the United States or the laws of
         the state of its  incorporation,  with  trust  power and  authority  to
         execute and deliver, and to carry out and perform its obligations under

         Trustee of this  Declaration  has been duly authorized by all necessary
         corporate action on the part of the Property  Trustee.  The Declaration
         has been duly  executed  and  delivered by the  Property  Trustee,  and

         other similar laws affecting creditors' rights generally and to general
         principles  of equity and the  discretion of the court  (regardless  of
         whether the  enforcement of such remedies is considered in a proceeding
         in equity or at law).

              (iii) The execution,  delivery and performance of this Declaration
         by the Property  Trustee does not conflict  with or constitute a breach
         of the Charter or By-laws of the Property Trustee.

                                    TERMS OF
                              PREFERRED SECURITIES

         Pursuant to Section  7.01 of the Amended and  Restated  Declaration  of
Trust of AES Trust II dated as of  October  29,  1997 (as  amended  from time to
time, the "Declaration"),  the designations,  rights, privileges,  restrictions,
preferences  and other terms and provisions of the Preferred  Securities are set
forth  below  (each  capitalized  term used but not  defined  herein  having the
meaning set forth in the Declaration):

         1. DESIGNATION AND NUMBER.  Preferred  Securities of the Trust with  an
aggregate liquidation amount in the assets of the Trust of Three Hundred Million
Dollars  ($300,000,000)  (plus up to an additional  Forty-Five  Million  Dollars
($45,000,000)  issuable upon exercise of the  overallotment  option set forth in
the Purchase  Agreement) and a liquidation  amount in the assets of the Trust of
$50 per Preferred  Security,  are hereby  designated as "$2.75 Term  Convertible
Securities,  Series B".  The  Preferred  Security  Certificates  evidencing  the
Preferred Securities shall be substantially in the form attached hereto as Annex
I, with such  changes and  additions  thereto or  deletions  therefrom as may be
required by ordinary usage, custom or practice or to conform to the rules of any
stock exchange on which the Preferred  Securities are listed. In connection with
the issuance and sale of the Preferred Securities and the Common Securities, the
Trust will  purchase  as trust  assets  Debentures  of AES  having an  aggregate
principal  amount equal to the  aggregate  liquidation  amount of the  Preferred
Securities  and Common  Securities  so issued and bearing  interest at an annual
rate equal to the  annual  Distribution  rate on the  Preferred  Securities  and
Common Securities and having payment and redemption  provisions which correspond
to the payment and redemption  provisions of the Preferred Securities and Common
Securities.

         2. DISTRIBUTIONS.  (a) Distributions payable on each Preferred Security
will be fixed  at a rate per  annum of $2.75  (the  "Coupon  Rate")  subject  to
increase in certain limited  circumstances  pursuant to the Registration  Rights
Agreement per  Preferred  Security.  Distributions  in arrears for more than one
calendar  quarter will bear  interest at the rate per annum of 5.50% thereof (to
the extent permitted by law), compounded quarterly.  The term "Distributions" as
used herein means such periodic cash distributions and any such interest payable
unless  otherwise  stated.  A Distribution  will be made by the Property Trustee
only to the extent that interest  payments are made in respect of the Debentures
held by the Property Trustee. The amount of Distributions payable for any period
will be computed for any quarterly Distribution period on the basis of a 360-day
year of twelve 30-day months.





<PAGE>


         (b) Distributions on the Preferred Securities will be cumulative,  will
accrue from October 29, 1997 and will be payable  quarterly  in arrears,  on the
last day of each quarter  commencing  on December 31, 1997,  except as otherwise
described below,  but only if and to the extent that interest  payments are made
in respect of the Debentures held by the Property Trustee.  So long as AES shall
not be in default in the  payment of  interest  on the  Debentures,  AES has the
right under the  Indenture for the  Debentures to defer  payments of interest by
extending the interest  payment period from time to time on the Debentures for a
period not  exceeding  20  consecutive  quarterly  interest  periods  (each,  an
"Extension Period") and, as a consequence, quarterly Distributions will continue
to accrue with interest  thereon (to the extent  permitted by applicable law) at
the rate of 5.50% per annum,  compounded  quarterly  during  any such  Extension
Period.  Prior to the termination of any such Extension Period,  AES may further
extend such Extension Period;  provided that such Extension Period together with
all such previous and further  extensions  thereof may not exceed 20 consecutive
quarterly  interest  periods;  and provided that no Extension  Period shall last
beyond the date of maturity or any redemption date of the Debentures..  Upon the
termination of any Extension Period and the payment of all amounts then due, AES
may commence a new Extension Period, subject to the above requirements. Payments
of accrued  Distributions will be payable to Holders of Preferred  Securities as
they appear on the books and records of the Trust on the first record date after
the end of the Extension Period.

         (c) Distributions on the Preferred  Securities will be payable promptly
by the  Property  Trustee (or other Paying  Agent) upon  receipt of  immediately
available  funds to the Holders  thereof as they appear on the books and records
of the Trust on the relevant record dates. While the Preferred Securities remain
in  book-entry  only form,  the relevant  record dates shall be one business day
prior to the relevant  Distribution date, and if the Preferred Securities are no
longer in book-entry  only form,  the Regular  Trustees  shall have the right to
select  relevant record dates which shall be more than one business day prior to
the relevant payment dates.  Distributions  payable on any Preferred  Securities
that are not punctually paid on any Distribution payment date as a result of AES
having failed to make the corresponding  interest payment on the Debentures will
forthwith  cease to be  payable  to the  person  in whose  name  such  Preferred
Security  is  registered  on  the  relevant  record  date,  and  such  defaulted
Distribution  will instead be payable to the person in whose name such Preferred
Security is registered  on the special  record date  established  by the Regular
Trustees, which record date shall correspond to the special record date or other
specified date determined in accordance with the Indenture;  provided,  however,
that Distributions  shall not be considered payable on any Distribution  payment
date falling within an Extension Period unless AES has elected to make a full or
partial  payment of  interest  accrued on the  Debentures  on such  Distribution
payment date.  Subject to any applicable laws and regulations and the provisions
of the Declaration,  each payment in respect of the Preferred Securities will be
made as described in paragraph 10




                                       2
<PAGE>


hereof.  If any  date  on  which  Distributions  are  payable  on the  Preferred
Securities is not a Business Day,  then payment of the  Distribution  payable on
such date will be made on the next  succeeding  day that is a Business  Day (and
without any interest or other payment in respect of any such delay) except that,
if such Business Day is in the next succeeding calendar year, such payment shall
be made on the  immediately  preceding  Business Day, in each case with the same
force and effect as if made on such date.

         (d) All Distributions paid with respect to the Preferred Securities and
the Common  Securities  will be paid Pro Rata to the  Holders  thereof  entitled
thereto.  If an Event of Default has occurred and is  continuing,  the Preferred
Securities  shall have a priority  over the Common  Securities  with  respect to
Distributions.

         (e) In the event of an election by the Holder to convert its Securities
through  the  Conversion  Agent into Common  Stock  pursuant to the terms of the
Securities  as set  forth in this  Exhibit  B to the  Declaration,  no  payment,
allowance or  adjustment  shall be made with respect to  accumulated  and unpaid
Distributions on such Securities, or be required to be made; provided,  however,
that if a Security is surrendered for conversion  after the close of business on
any regular record date for payment of a Distribution  and before the opening of
business on the  corresponding  Distribution  date, then,  notwithstanding  such
conversion,  the Distribution  payable on such Distribution date will be paid in
cash to the  person in whose name the  Security  is  registered  at the close of
business  on such  record  date,  and (other  than a Security  or a portion of a
Security  called for redemption on a redemption date occurring after such record
date  and on or  prior  to  such  Distribution  date)  when so  surrendered  for
conversion,  the Security must be  accompanied  by payment of an amount equal to
the Distribution payable on such Distribution date.

         (f) In the event that there is any money or other  property  held by or
for the Trust that is not  accounted  for under the  Declaration,  such money or
property  shall be  distributed  Pro Rata  among the  Holders  of the  Preferred
Securities and Common Securities.

         3.  LIQUIDATION  DISTRIBUTION  UPON  DISSOLUTION.  In the  event of any
voluntary or  involuntary  dissolution,  winding-up or termination of the Trust,
the Holders of the Preferred Securities and Common Securities at the date of the
dissolution,  winding-up or termination, as the case may be, will be entitled to
receive  Pro  Rata  solely  out  of  the  assets  of  the  Trust  available  for
distribution  to Holders of Preferred  Securities  and Common  Securities  after
satisfaction  of liabilities  to creditors,  an amount equal to the aggregate of
the stated  liquidation amount of $50 per Preferred Security and Common Security
plus  accrued  and unpaid  Distributions  thereon  to the date of payment  (such
amount being the "Liquidation  Distribution"),  unless,  in connection with such
dissolution, winding-up or termination, and after




                                       3
<PAGE>


satisfaction of liabilities to creditors,  Debentures in an aggregate  principal
amount  equal to the  aggregate  stated  liquidation  amount  of such  Preferred
Securities and Common  Securities and bearing  accrued and unpaid interest in an
amount  equal  to the  accrued  and  unpaid  Distributions  on,  such  Preferred
Securities and Common  Securities,  shall be distributed Pro Rata to the Holders
of  the  Preferred  Securities  and  Common  Securities  in  exchange  for  such
Securities.

         If, upon any such dissolution, the Liquidation Distribution can be paid
only in part because the Trust has insufficient  assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the Preferred  Securities and Common Securities shall be paid,  subject
to the next paragraph, on a Pro Rata basis.

         Holders of Common  Securities  will be entitled to receive  Liquidation
Distributions  upon any such  dissolution  Pro Rata with  Holders  of  Preferred
Securities,  except that if an Event of Default has occurred and is  continuing,
the Preferred  Securities shall have a priority over the Common  Securities with
respect to such Liquidation Distribution.

         4. REDEMPTION AND DISTRIBUTION OF DEBENTURES.  The Preferred Securities
and Common  Securities  may only be redeemed if  Debentures  having an aggregate
principal  amount equal to the  aggregate  liquidation  amount of the  Preferred
Securities  and Common  Securities  are repaid,  redeemed or  distributed as set
forth below:

         (a) Upon the repayment of the Debentures,  in whole or in part, whether
at  maturity,  upon  redemption  at any  time or from  time to time on or  after
September 30, 2000, or at any time in certain  circumstances upon the occurrence
of a Tax Event,  the  proceeds of such  repayment  will be  promptly  applied to
redeem Pro Rata Preferred  Securities and Common  Securities having an aggregate
liquidation amount equal to the aggregate  principal amount of the Debentures so
repaid or redeemed,  upon not less than 30 nor more than 60 days'  notice,  at a
redemption price per Preferred and Common Security equal to the redemption price
of the  Debentures,  together  with  accrued  and unpaid  Distributions  thereon
through the date of redemption,  payable in cash (the "Redemption  Price").  The
date of any such  repayment or  redemption  of Preferred  Securities  and Common
Securities  shall be  established  to coincide  with the repayment or redemption
date of the Debentures.

         (b) If fewer than all the outstanding  Preferred  Securities and Common
Securities  are to be so  redeemed,  the  Preferred  Securities  and the  Common
Securities will be redeemed Pro Rata and the Preferred Securities to be redeemed
will be  redeemed  as  described  in  paragraph  4(f)(ii)  below.  If a  partial
redemption  would result in the  delisting of the  Preferred  Securities  by any
national  securities  exchange  or other  organization  on which  the  Preferred
Securities are then listed, AES pursuant




                                       4
<PAGE>


to the  Indenture  will only redeem  Debentures  in whole and, as a result,  the
Trust may only redeem the Preferred Securities in whole.

         (c) If, at any time, a Tax Event or an  Investment  Company Event (each
as  hereinafter  defined,  and  each  a  "Special  Event")  shall  occur  and be
continuing,  the Regular  Trustees shall,  unless the Debentures are redeemed in
the  limited  circumstances  described  below,  dissolve  the Trust  and,  after
satisfaction of creditors,  cause Debentures held by the Property Trustee having
an aggregate  principal amount equal to the aggregate stated  liquidation amount
of and accrued and unpaid interest equal to accrued and unpaid Distributions on,
and having the same  record  date for payment as the  Preferred  Securities  and
Common Securities,  to be distributed to the Holders of the Preferred Securities
and  Common  Securities  on a Pro Rata  basis in  liquidation  of such  Holders'
interests in the Trust,  within 90 days following the occurrence of such Special
Event  (the  "90  Day  Period"),  provided,  however,  that  in the  case of the
occurrence of a Tax Event, as a condition of such dissolution and  distribution,
the Regular  Trustees shall have received an opinion of a nationally  recognized
independent  tax  counsel   experienced  in  such  matters  (a  "No  Recognition
Opinion"),  which  opinion  may rely on any then  applicable  published  revenue
ruling of the Internal  Revenue  Service,  to the effect that the Holders of the
Preferred  Securities  will not  recognize  any gain or loss for  United  States
federal  income tax  purposes  as a result of the  dissolution  of the Trust and
distribution of Debentures;  and provided,  further,  that, if and as long as at
the time there is available to the Trust the  opportunity  to eliminate,  within
the 90 Day Period, the Special Event by taking some ministerial  action, such as
filing a form or making an election,  or pursuing some other similar  reasonable
measure  that has no  adverse  effect on the  Trust,  AES or the  Holders of the
Preferred Securities  ("Ministerial Action"), the Trust will pursue such measure
in lieu of dissolution.

         If in the  case of the  occurrence  of a Tax  Event,  (i)  the  Regular
Trustees  have  received an opinion (a  "Redemption  Tax Opinion") of nationally
recognized independent tax counsel experienced in such matters that, as a result
of a Tax  Event,  there is more  than an  insubstantial  risk  that AES would be
precluded  from  deducting  the  interest on the  Debentures  for United  States
federal  income tax purposes  even if the  Debentures  were  distributed  to the
Holders of Preferred  Securities  and Common  Securities in  liquidation of such
Holder's  interest in the Trust as described in this  paragraph 4(c) or (ii) the
Regular  Trustees  shall  have  been  informed  by such  tax  counsel  that a No
Recognition  Opinion cannot be delivered to the Trust,  AES shall have the right
at any time, upon not less than 30 nor more than 60 days' notice,  to redeem the
Debentures in whole or in part for cash at the  Redemption  Price within 90 days
following  the  occurrence  of such  Tax  Event,  and  promptly  following  such
redemption   Preferred  Securities  and  Common  Securities  with  an  aggregate
liquidation amount equal to the aggregate  principal amount of the Debentures so
redeemed  will be  redeemed by the Trust at the  Redemption  Price on a Pro Rata
basis; provided,




                                       5
<PAGE>


however,  that, if at the time there is available to AES or the Regular Trustees
on behalf of the Trust the opportunity to eliminate,  within such 90 day period,
the Tax Event by taking some Ministerial  Action, AES or the Regular Trustees on
behalf  of the  Trust  will  pursue  such  measure  in lieu of  redemption  and;
provided,  further,  that AES shall have no right to redeem the Debentures while
the  Regular  Trustees  on behalf of the Trust  are  pursuing  such  Ministerial
Action.  The Common  Securities  will be  redeemed  Pro Rata with the  Preferred
Securities,  except that if an Event of Default under the Indenture has occurred
and is continuing, the Preferred Securities will have a priority over the Common
Securities with respect to payment of the Redemption Price.

         "Tax Event"  means that the  Regular  Trustees  shall have  obtained an
opinion of nationally  recognized  independent  tax counsel  experienced in such
matters (a "Dissolution Tax Opinion") to the effect that on or after October 23,
1997 as a result of (a) any  amendment  to, or change  (including  any announced
prospective  change) in, the laws (or any regulations  thereunder) of the United
States or any political  subdivision or taxing authority thereof or therein, (b)
any amendment to, or change in, an  interpretation  or  application  of any such
laws or regulations  by any  legislative  body,  court,  governmental  agency or
regulatory  authority  (including  the  enactment  of any  legislation  and  the
publication  of any  judicial  decision or  regulatory  determination),  (c) any
interpretation  or  pronouncement  that  provides for a position with respect to
such laws or regulations  that differs from the theretofore  generally  accepted
position  or (d) any  action  taken by any  governmental  agency  or  regulatory
authority,  which  amendment  or  change  is  enacted,  promulgated,  issued  or
announced or which  interpretation  or  pronouncement  is issued or announced or
which action is taken, in each case on or after October 23, 1997,  there is more
than an  insubstantial  risk that (i) the Trust is, or will be within 90 days of
the date thereof,  subject to United States  federal  income tax with respect to
income  accrued or  received  on the  Debentures,  (ii) the Trust is, or will be
within 90 days of the date thereof,  subject to more than a de minimis amount of
other taxes,  duties or other governmental  charges or (iii) interest payable by
AES to the Trust on the Debentures is not, or within 90 days of the date thereof
will not be, deductible by AES for United States federal income tax purposes.

         "Investment  Company Event" means that the Regular  Trustees shall have
received an opinion of nationally recognized  independent counsel experienced in
practice under the Investment Company Act that, as a result of the occurrence of
a change in law or regulation or a change in  interpretation  or  application of
law or  regulation  by any  legislative  body,  court,  governmental  agency  or
regulatory  authority  (a  "Change  in 1940 Act  Law"),  there  is more  than an
insubstantial risk that the Trust is or will be considered an Investment Company
which is required to be  registered  under the  Investment  Company  Act,  which
Change in 1940 Act Law becomes effective on or after October 23, 1997.




                                       6

         On the date fixed for any distribution of Debentures,  upon dissolution
of the  Trust,  (i) the  Preferred  Securities  will no  longer  be deemed to be
outstanding  and (ii)  certificates  representing  Preferred  Securities will be
deemed to represent  beneficial  interests in the Debentures having an aggregate
principal amount equal to the stated  liquidation amount of, and bearing accrued
and unpaid interest equal to accrued and unpaid Distributions on, such Preferred
Securities  until  such  certificates  are  presented  to AES or its  agent  for
transfer or reissuance.

         (d) The Trust  may not  redeem  any  outstanding  Preferred  Securities
unless all  accrued  and unpaid  Distributions  have been paid on all  Preferred
Securities for all quarterly Distribution periods terminating on or prior to the
date of redemption.

         (e)  If  Debentures  are   distributed  to  Holders  of  the  Preferred
Securities,  AES,  pursuant  to the  terms of the  Indenture,  will use its best
efforts to have the Debentures  listed on the New York Stock Exchange or on such
other exchange as the Preferred  Securities were listed immediately prior to the
distribution of the Debentures.

         (f) (i)  Notice of any  redemption  of, or  notice of  distribution  of
Debentures in exchange for, the Preferred  Securities  and Common  Securities (a
"Redemption/  Distribution  Notice")  will be given by the  Regular  Trustees on
behalf of the Trust by mail to each Holder of  Preferred  Securities  and Common
Securities  to be redeemed or  exchanged  not less than 30 nor more than 60 days
prior to the date fixed for redemption or exchange thereof.  For purposes of the
calculation of the date of redemption or exchange and the dates on which notices
are given pursuant to this paragraph  (f)(i), a  Redemption/Distribution  Notice
shall  be  deemed  to be  given  on the day  such  notice  is  first  mailed  by
first-class mail, postage prepaid, to Holders of Preferred Securities and Common
Securities.  Each  Redemption/Distribution  Notice  shall  be  addressed  to the
Holders of Preferred  Securities  and Common  Securities  at the address of each
such Holder  appearing  in the books and records of the Trust.  No defect in the
Redemption/Distribution  Notice or in the mailing of either thereof with respect
to  any  Holder  shall  affect  the  validity  of  the  redemption  or  exchange
proceedings with respect to any other Holder.

         (ii)  In the  event  that  fewer  than  all the  outstanding  Preferred
Securities are to be redeemed,  the Preferred  Securities to be redeemed will be
redeemed Pro Rata from each Holder of Preferred Securities,  it being understood
that, in respect of Preferred  Securities  registered in the name of and held of
record by DTC (or successor Clearing Agency) or any other nominee, the Preferred
Securities  will be redeemed from, and the  distribution of the proceeds of such
redemption will be made to, each Clearing Agency Participant (or person on whose
behalf such nominee holds such  securities)  in accordance  with the  procedures
applied by such agency or nominee.





                                       7

         (iii) Subject to paragraph 10 hereof,  if the Trust gives a Redemption/
Distribution  Notice in respect  of a  redemption  of  Preferred  Securities  as
provided in this paragraph 4 (which notice will be  irrevocable)  then (A) while
the  Preferred  Securities  are in  book-entry  only form,  with  respect to the
Preferred Securities, by 12:00 noon, New York City time, on the redemption date,
provided that AES has paid the Property Trustee, in immediately available funds,
a  sufficient  amount  of cash in  connection  with the  related  redemption  or
maturity of the Debentures,  the Property Trustee will deposit  irrevocably with
DTC (or  successor  Clearing  Agency)  funds  sufficient  to pay the  applicable
Redemption Price with respect to the Preferred  Securities and will give DTC (or
successor  Clearing  Agency)  irrevocable  instructions and authority to pay the
Redemption  Price to the  Holders  of the  Preferred  Securities  and (B) if the
Preferred  Securities  are  issued  in  definitive  form,  with  respect  to the
Preferred  Securities  and provided that AES has paid the Property  Trustee,  in
immediately  available funds, a sufficient amount of cash in connection with the
related redemption or maturity of the Debentures,  the Property Trustee will pay
the relevant  Redemption  Price to the Holders of such  Preferred  Securities by
check  mailed to the address of the relevant  Holder  appearing on the books and
records of the Trust on the redemption date. If a Redemption/Distribution Notice
shall have been given and funds  deposited  as  required,  if  applicable,  then
immediately  prior  to the  close  of  business  on the  date of  such  deposit,
Distributions  will  cease to  accrue on the  Preferred  Securities  called  for
redemption, such Preferred Securities will no longer be deemed to be outstanding
and all rights of Holders of such Preferred  Securities so called for redemption
will cease,  except the right of the  Holders of such  Preferred  Securities  to
receive the Redemption  Price,  but without  interest on such Redemption  Price.
Neither the  Trustees nor the Trust shall be required to register or cause to be
registered  the transfer of any Preferred  Securities  which have been so called
for redemption.  If any date fixed for redemption of Preferred Securities is not
a Business Day, then payment of the  Redemption  Price payable on such date will
be made on the next  succeeding  day that is a  Business  Day (and  without  any
interest or other  payment in respect of any such delay)  except  that,  if such
Business Day falls in the next calendar  year,  such payment will be made on the
immediately  preceding Business Day, in each case with the same force and effect
as if made on such date fixed for redemption.  If AES fails to repay  Debentures
on  maturity  or on the date  fixed for this  redemption  or if  payment  of the
Redemption  Price in respect of Preferred  Securities is improperly  withheld or
refused and not paid either by the  Property  Trustee or by AES  pursuant to the
Preferred Securities Guarantee,  Distributions on such Preferred Securities will
continue to accrue, from the original redemption date to the date of payment, in
which  case the  actual  payment  date  will be  considered  the date  fixed for
redemption for purposes of calculating the Redemption Price.

         (iv)  Redemption/Distribution  Notices  shall  be sent  by the  Regular
Trustees on behalf of the Trust to DTC or its nominee (or any successor Clearing
Agency or its




                                       8
<PAGE>


nominee) if the Global Certificates have been issued or, if Definitive Preferred
Security  Certificates  have  been  issued,  to the  Holders  of  the  Preferred
Securities.

         (v) Upon the date of  dissolution  of the  Trust  and  distribution  of
Debentures as a result of the occurrence of a Special Event,  Preferred Security
Certificates shall be deemed to represent beneficial interests in the Debentures
so  distributed,   and  the  Preferred  Securities  will  no  longer  be  deemed
outstanding  and may be canceled  by the Regular  Trustees.  The  Debentures  so
distributed  shall have an aggregate  principal  amount  equal to the  aggregate
liquidation amount of the Preferred Securities so distributed.

         (vi) Subject to the foregoing and  applicable law  (including,  without
limitation,   United  States  federal  securities  laws),  AES  or  any  of  its
subsidiaries  may at any  time  and  from  time  to  time  purchase  outstanding
Preferred Securities by tender, in the open market or by private agreement.

         5. CONVERSION RIGHTS. The Holders of Securities shall have the right at
any time prior to the close of business on  September  30, 2012 (or, in the case
of  Securities  called for  redemption,  prior to the close of  business  on the
Business  Day  prior to the  redemption  date),  at their  option,  to cause the
Conversion  Agent to convert  Securities,  on behalf of the converting  Holders,
into shares of Common Stock in the manner described herein on and subject to the
following terms and conditions:

         The  Securities  will be  convertible  at the office of the  Conversion
Agent into fully paid and  nonassessable  shares of Common Stock pursuant to the
Holder's  direction to the  Conversion  Agent to exchange such  Securities for a
portion  of the  Debentures  theretofore  held by the  Trust on the basis of one
Security per $50 principal  amount of Debentures,  and immediately  convert such
amount of Debentures into fully paid and nonassessable shares of Common Stock at
an initial  rate of 0.8914  shares of Common Stock per $50  principal  amount of
Debentures  (which is  equivalent  to a conversion  price of $56.09 per share of
Common Stock, subject to certain adjustments set forth in Sections 5.03 and 5.04
of the Supplemental Indenture (as so adjusted, the "Conversion Price")).

         (a) In order to convert  Securities  into Common Stock the Holder shall
submit to the  Conversion  Agent at the office  referred to above an irrevocable
request  to  convert  Securities  on  behalf  of such  Holder  (the  "Conversion
Request"),  together,  if the Securities  are in  certificated  form,  with such
certificates.  The  Conversion  Request  shall  (i)  set  forth  the  number  of
Securities to be converted and the name or names,  if other than the Holder,  in
which the shares of Common Stock should be issued and (ii) direct the Conversion
Agent (a) to exchange such  Securities for a portion of the  Debentures  held by
the Trust (at the rate of exchange specified in the preceding paragraph) and (b)
to immediately convert such Debentures on behalf of





                                       9
<PAGE>


such  Holder,  into  Common  Stock  (at the  conversion  rate  specified  in the
preceding paragraph).  The Conversion Agent shall notify the Property Trustee of
the Holder's  election to exchange  Securities  for a portion of the  Debentures
held by the Trust and the Property  Trustee shall,  upon receipt of such notice,
deliver to the Conversion  Agent the appropriate  principal amount of Debentures
for  exchange  in  accordance  with this  Section.  The  Conversion  Agent shall
thereupon notify the Property  Trustee of the Holder's  election to convert such
Debentures  into  shares of Common  Stock.  If a  Security  is  surrendered  for
conversion after the close of business on any regular record date for payment of
a  Distribution  and  before  the  opening  of  business  on  the  corresponding
Distribution   payment  date,  then,   notwithstanding   such  conversion,   the
Distribution  payable on such Distribution  payment date will be paid in cash to
the person in whose name the Security is  registered at the close of business on
such record date,  and (other than a Security or a portion of a Security  called
for redemption on a redemption  date occurring  after such record date and on or
prior to such Distribution payment date) when so surrendered for conversion, the
Security must be accompanied  by payment of an amount equal to the  Distribution
payable on such Distribution payment date. Except as provided above, neither the
Trust nor the Sponsor will make, or be required to make, any payment,  allowance
or  adjustment  upon any  conversion  on account of any  accumulated  and unpaid
Distributions  accumulated on the Securities  surrendered for conversion,  or on
account of any  accumulated  and unpaid  dividends on the shares of Common Stock
issued upon such  conversion.  Securities shall be deemed to have been converted
immediately  prior to the close of business  on the day on which the  Conversion
Request  relating to such Securities is received by the Trust in accordance with
the foregoing  provision (the "Conversion Date"). The Person or Persons entitled
to receive  Common Stock  issuable upon  conversion of the  Debentures  shall be
treated for all purposes as the record holder or holders of such Common Stock at
such time.  As promptly as  practicable  on or after the  Conversion  Date,  the
Sponsor  shall  issue  and  deliver  at the  office  of the  Conversion  Agent a
certificate  or  certificates  for the  number of full  shares  of Common  Stock
issuable upon such conversion,  together with the cash payment,  if any, in lieu
of any  fraction  of any share to the Person or Persons  entitled to receive the
same, unless otherwise  directed by the Holder in the Conversion Request and the
Conversion Agent shall  distribute such  certificate or  certificates,  together
with the applicable cash payment, if any, to such Person or Persons.

         (b) Each Holder of a Security by his  acceptance  thereof  appoints The
First National Bank of Chicago  "Conversion  Agent" for the purpose of effecting
the conversion of Securities in accordance  with this Section.  In effecting the
conversion and  transactions  described in this Section,  the  Conversion  Agent
shall be acting as agent of the  Holders of  Securities  directing  it to effect
such conversion  transactions.  The Conversion Agent is hereby authorized (i) to
exchange  Securities  from  time to time  for  Debentures  held by the  Trust in
connection  with the  conversion  of such  Securities  in  accordance  with this
section and (ii) to convert all or a portion of the





                                       10
<PAGE>


Debentures  into Common  Stock and  thereupon  to deliver  such shares of Common
Stock in  accordance  with the  provisions of this section and to deliver to the
Trust a new Debenture or  Debentures  for any  resulting  unconverted  principal
amount.

         (c) No fractional  shares of Common Stock will be issued as a result of
conversion,  but in lieu thereof,  such fractional interest will be paid in cash
by the Sponsor to the Conversion Agent,  which in turn will make such payment to
the Holder or Holders of Securities so converted.

         (d) The Sponsor  shall at all times  reserve and keep  available out of
its  authorized  and  unissued  Common  Stock,  solely  for  issuance  upon  the
conversion of the Debentures,  free from any preemptive or other similar rights,
such  number of shares of Common  Stock as shall  from time to time be  issuable
upon the conversion of all the Debentures then outstanding.  Notwithstanding the
foregoing,  the  Sponsor  shall  be  entitled  to  deliver  upon  conversion  of
Debentures,  shares of Common Stock  reacquired  and held in the treasury of the
Sponsor (in lieu of the issuance of  authorized  and  unissued  shares of Common
Stock),  so long as any such  treasury  shares  are free and clear of all liens,
charges,  security interests or encumbrances.  Any shares of Common Stock issued
upon conversion of the Debentures shall be duly  authorized,  validly issued and
fully paid and nonassessable. The Trust shall deliver the shares of Common Stock
received upon  conversion of the  Debentures to the  converting  Holder free and
clear of all liens,  charges,  security  interests and encumbrances,  except for
United States withholding taxes. Each of the Sponsor and the Trust shall prepare
and shall use its best efforts to obtain and keep in force such  governmental or
regulatory permits or other  authorizations as may be required by law, and shall
comply with all applicable  requirements as to registration or  qualification of
Common Stock (and all requirements to list Common Stock issuable upon conversion
of Debentures that are at the time  applicable),  in order to enable the Sponsor
to lawfully  issue Common Stock to the Trust upon  conversion of the  Debentures
and the Trust to lawfully deliver Common Stock to each Holder upon conversion of
the Securities.

         (e) The  Sponsor  will pay any and all  taxes  that may be  payable  in
respect of the issue or  delivery  of shares of Common  Stock on  conversion  of
Debentures  and the  delivery  of the  shares of Common  Stock by the Trust upon
conversion of the Securities. The Sponsor shall not, however, be required to pay
any tax which may be payable in respect of any  transfer  involved  in the issue
and  delivery  of shares of Common  Stock in a name other than that in which the
Securities so converted were registered,  and no such issue or delivery shall be
made unless and until the person requesting such issue has paid to the Trust the
amount of any such tax, or has established to the satisfaction of the Trust that
such tax has been paid.



                                       11
<PAGE>


         (f) Nothing in the preceding  Paragraph (e) shall limit the requirement
of the Trust to withhold  taxes  pursuant to the terms of the  Securities as set
forth in this  Exhibit  B to the  Declaration  or to the  Declaration  itself or
otherwise  require  the  Property  Trustee  or the Trust to pay any  amounts  on
account of such withholdings.

         6. VOTING RIGHTS. (a) Except as provided under paragraph 6(b) below and
as otherwise  required by law and the Declaration,  the Holders of the Preferred
Securities will have no voting rights.

         (b) If any proposed  amendment to the Declaration  provides for, or the
Regular  Trustees  otherwise  propose  to  effect,  (i) any  action  that  would
adversely  affect the powers,  preferences or special rights of the  Securities,
whether  by way of  amendment  to the  Declaration  or  otherwise,  or (ii)  the
dissolution,  winding-up or termination  of the Trust,  other than in connection
with the  distribution  of  Debentures  held by the Property  Trustee,  upon the
occurrence of a Special Event or in connection  with the redemption of Preferred
Securities as a consequence of a redemption of  Debentures,  then the Holders of
outstanding Securities will be entitled to vote on such amendment or proposal as
a class and such  amendment or proposal  shall not be effective  except with the
approval of the Holders of  Securities  representing  a Majority in  liquidation
amount of such  Securities;  provided,  however,  that (A) if any  amendment  or
proposal  referred  to in  clause  (i) above  would  adversely  affect  only the
Preferred Securities or the Common Securities, then only the affected class will
be entitled to vote on such amendment or proposal and such amendment or proposal
shall not be  effective  except with the  approval of a Majority in  liquidation
amount of such class of Securities and (B) amendments to the  Declaration  shall
be subject to such further  requirements  as are set forth in Sections 12.01 and
12.02 of the Declaration.

         In the event the consent of the Property Trustee,  as the holder of the
Debentures,  is required  under the  Indenture  with  respect to any  amendment,
modification  or  termination of the Indenture or the  Debentures,  the Property
Trustee  shall  request the written  direction of the Holders of the  Securities
with  respect to such  amendment,  modification  or  termination.  The  Property
Trustee shall vote with respect to such  amendment,  modification or termination
as  directed  by a  Majority  in  liquidation  amount of the  Securities  voting
together as a single class; provided that where such amendment,  modification or
termination  of the  Indenture  requires  the  consent or vote of (1) holders of
Debentures  representing  a  specified  percentage  greater  than a majority  in
principal  amount  of the  Debentures  or (2) each  holder  of  Debentures,  the
Property  Trustee may only vote with respect to that amendment,  modification or
termination as directed by, in the case of clause (1) above, the vote of Holders
of  Securities   representing   such  specified   percentage  of  the  aggregate
liquidation amount of the Securities,  or, in the case of clause (2) above, each
Holder of Securities; and provided,  further, that the Property Trustee shall be
under no obligation to take any action in accordance  with the directions of the
Holders of




                                       12
<PAGE>


Securities  unless the Property  Trustee shall have received,  at the expense of
the  Sponsor,  an opinion  of  nationally  recognized  independent  tax  counsel
recognized  as expert in such  matters to the effect  that the Trust will not be
classified  for United  States  federal  income tax  purposes as an  association
taxable as a corporation  or a partnership on account of such action and will be
treated  as a grantor  trust for  United  States  federal  income  tax  purposes
following such action.

         Subject to Section 2.06 of the Declaration,  and the provisions of this
and the next  succeeding  paragraph,  the Holders of a Majority  in  liquidation
amount of the Preferred Securities,  voting separately as a class shall have the
right to (A) on behalf of all Holders of  Preferred  Securities,  waive any past
default that is waivable  under the  Declaration  (subject to, and in accordance
with the  Declaration)  and (B) direct the time,  method and place of conducting
any proceeding for any remedy available to the Property  Trustee,  or exercising
any trust or power  conferred upon the Property  Trustee under the  Declaration,
including  the  right to  direct  the  Property  Trustee,  as the  holder of the
Debentures,  to (i)  direct  the  time,  method  and  place  of  conducting  any
proceeding for any remedy available to the Debenture Trustee,  or exercising any
trust  or  power  conferred  on  the  Debenture  Trustee  with  respect  to  the
Debentures,  (ii) waive any past default that is waivable  under Section 6.06 of
the  Indenture,  or (iii)  exercise any right to rescind or annul a  declaration
that the principal of all the Debentures shall be due and payable; provided that
where the taking of any action under the Indenture  requires the consent or vote
of (1) holders of Debentures  representing a specified percentage greater than a
majority in principal amount of the Debentures or (2) each holder of Debentures,
the  Property  Trustee may only take such action if directed  by, in the case of
clause (1) above, the vote of Holders of Preferred Securities  representing such
specified  percentage  of the  aggregate  liquidation  amount  of the  Preferred
Securities,  or, in the case of  clause  (2)  above,  each  Holder of  Preferred
Securities.  The  Property  Trustee  shall  not  revoke  any  action  previously
authorized  or approved by a vote of the  Holders of the  Preferred  Securities.
Other than with respect to directing  the time,  method and place of  conducting
any proceeding for any remedy available to the Property Trustee or the Debenture
Trustee as set forth above, the Property Trustee shall be under no obligation to
take any of the  foregoing  actions at the direction of the Holders of Preferred
Securities  unless the Property  Trustee shall have received,  at the expense of
the  Sponsor,  an opinion  of  nationally  recognized  independent  tax  counsel
recognized  as expert in such  matters to the effect  that the Trust will not be
classified  for United  States  federal  income tax  purposes as an  association
taxable as a corporation  or a partnership on account of such action and will be
treated  as a grantor  trust for  United  States  federal  income  tax  purposes
following such action. If the Property Trustee fails to enforce its rights under
the  Declaration  (including,   without  limitation,   its  rights,  powers  and
privileges as a holder of the  Debentures  under the  Indenture),  any Holder of
Preferred  Securities may, to the extent  permitted by law, after a period of 30
days has elapsed from such Holder's  written request to the Property  Trustee to
enforce such rights, institute a




                                       13
<PAGE>

legal proceeding  directly against AES to enforce the Property  Trustee's rights
under the Declaration,  without first instituting a legal proceeding against the
Property Trustee or any other Person. Notwithstanding the foregoing, if an Event
of Default has occurred and is continuing and such event is  attributable to the
failure of the Sponsor to pay  interest or principal  on the  Debentures  on the
date  such  interest  or  principal  is  otherwise  payable  (or in the  case of
redemption, on the redemption date), then the registered holder of the Preferred
Securities  may directly  institute a proceeding  for  enforcement of payment to
such holder of the principal of or interest on the Debentures having a principal
amount equal to the aggregate  liquidation amount of the Preferred Securities of
such  Holder (a "Holder  Direct  Action")  on or after the  respective  due date
specified in the Debentures.  In connection with such Holder Direct Action,  the
Sponsor will be subrogated to the rights of such Holder of Preferred  Securities
under the  Declaration  to the extent of any payment made by the Sponsor to such
Holder of Preferred Securities in such Holder Direct Action.  Except as provided
in the preceding sentences, the holders of Preferred Securities will not be able
to exercise any other remedy available to the holders of the Debentures.

         A waiver of an Indenture  Event of Default by the  Property  Trustee at
the  direction  of the Holders of the  Preferred  Securities  will  constitute a
waiver of the corresponding Event of Default under the Declaration in respect of
the Securities.

         Any required  approval or direction of Holders of Preferred  Securities
may be given at a separate meeting of Holders of Preferred  Securities  convened
for such purpose,  at a meeting of all of the Holders of Securities of the Trust
or pursuant to written consent.  The Regular Trustees will cause a notice of any
meeting at which Holders of Preferred Securities are entitled to vote, or of any
matter upon which action by written  consent of such Holders is to be taken,  to
be mailed to each  Holder of record of  Preferred  Securities.  Each such notice
will include a statement  setting forth (i) the date of such meeting or the date
by which  such  action  is to be taken,  (ii) a  description  of any  resolution
proposed for adoption at such meeting on which such Holders are entitled to vote
or of such matter upon which  written  consent is sought and (iii)  instructions
for the delivery of proxies or consents.

         No vote or  consent  of the  Holders of  Preferred  Securities  will be
required for the Trust to redeem and cancel  Preferred  Securities or distribute
Debentures in accordance with the Declaration.

         Notwithstanding  that Holders of Preferred  Securities  are entitled to
vote or  consent  under any of the  circumstances  described  above,  any of the
Preferred  Securities  at such  time  that  are  owned  by AES or by any  entity
directly or indirectly  controlling or controlled by or under direct or indirect
common control with AES shall not be entitled to vote or consent and shall,  for
purposes of such vote or consent, be treated as if they were not outstanding.






                                       14
<PAGE>


         Except as  provided  in this  paragraph  6,  Holders  of the  Preferred
Securities will have no rights to increase or decrease the number of Trustees or
to appoint,  remove or replace a Trustee,  which voting rights are vested solely
in the Holders of the Common Securities.

         7. PRO RATA  TREATMENT.  A reference  in these  terms of the  Preferred
Securities to any payment,  distribution  or treatment as being "Pro Rata" shall
mean  pro  rata  to  each  Holder  of  Securities  according  to  the  aggregate
liquidation  amount of the Securities held by the relevant Holder in relation to
the  aggregate  liquidation  amount of all  Securities  outstanding  unless,  in
relation to a payment,  an Event of Default has occurred and is  continuing,  in
which case any funds  available to make such payment shall be paid first to each
Holder  of  the  Preferred  Securities  pro  rata  according  to  the  aggregate
liquidation amount of Preferred  Securities held by the relevant Holder relative
to the aggregate liquidation amount of all Preferred Securities outstanding, and
only after  satisfaction  of all amounts  owed to the  Holders of the  Preferred
Securities,  to each  Holder  of Common  Securities  pro rata  according  to the
aggregate  liquidation  amount of Common  Securities held by the relevant Holder
relative  to  the  aggregate   liquidation   amount  of  all  Common  Securities
outstanding.

         8.  RANKING.  The  Preferred  Securities  rank pari  passu and  payment
thereon  will be made Pro Rata with the Common  Securities  except that where an
Event of Default  occurs and is  continuing,  the rights of Holders of Preferred
Securities to payment in respect of Distributions and payments upon liquidation,
redemption or otherwise  rank in priority to the rights of Holders of the Common
Securities.

         9.  MERGERS,  CONSOLIDATIONS  OR  AMALGAMATIONS.   The  Trust  may  not
consolidate,  amalgamate,  merge  with or into,  or be  replaced  by, or convey,
transfer or lease its properties and assets to, any corporation or other entity.

         10. TRANSFER,  EXCHANGE,  METHOD OF PAYMENTS.  Payment of Distributions
and payments on  redemption  of the Preferred  Securities  will be payable,  the
transfer  of  the  Preferred  Securities  will  be  registrable,  and  Preferred
Securities will be exchangeable for Preferred  Securities of other denominations
of a like aggregate  liquidation amount, at the principal corporate trust office
of the  Property  Trustee  in The City of New York;  provided  that  payment  of
Distributions may be made at the option of the Regular Trustees on behalf of the
Trust by check  mailed to the address of the persons  entitled  thereto and that
the  payment on  redemption  of any  Preferred  Security  will be made only upon
surrender of such Preferred Security to the Property Trustee.

         11.  ACCEPTANCE OF INDENTURE AND  PREFERRED  GUARANTEE.  Each Holder of
Preferred Securities, by the acceptance thereof, agrees to the provisions of (i)
the Preferred Guarantee, including the subordination provisions therein and (ii)
the




                                       15
<PAGE>

Indenture  and the  Debentures,  including the  subordination  provisions of the
Indenture.

         12. NO PREEMPTIVE  RIGHTS.  The Holders of Preferred  Securities  shall
have no preemptive rights to subscribe to any additional Preferred Securities or
Common Securities.

         13.  MISCELLANEOUS.   These  terms  shall  constitute  a  part  of  the
Declaration.  The Trust will provide a copy of the Declaration and the Indenture
to a Holder  without  charge on written  request  to the Trust at its  principal
place of business.

9.01(d) of the Declaration.]

         AES Trust II, a statutory  business trust created under the laws of the
State of Delaware (the "Trust"),  hereby certifies that _________ (the "Holder")
is the registered  owner of  ___________  (______)  preferred  securities of the
Trust  representing  undivided  beneficial  interests in the assets of the Trust
designated the $2.75 Term Convertible  Securities,  Series B (liquidation amount
$50 per security) (the  "Preferred  Securities").  The Preferred  Securities are
transferable  on the  books and  records  of the  Trust,  in person or by a duly
authorized  attorney,  upon surrender of this  certificate  duly endorsed and in
proper form for transfer. The designations,  rights,  privileges,  restrictions,
preferences  and other terms and provisions of the Preferred  Securities are set
forth in, and this certificate and the Preferred  Securities  represented hereby
are issued and shall in all respects be subject to the terms and  provisions of,
the Amended and Restated  Declaration  of Trust of the Trust dated as of October
29,  1997,  as the same may be  amended  from time to time  (the  "Declaration")
including the  designation of the terms of Preferred  Securities as set forth in
Exhibit B thereto.  The Preferred Securities and the Common Securities issued by
the Trust pursuant to the Declaration  represent undivided  beneficial interests
in the  assets  of the  Trust,  including  the  Debentures  (as  defined  in the
Declaration) issued by The AES Corporation,  a Delaware  corporation ("AES"), to
the Trust pursuant to the Indenture  referred to in the Declaration.  The Holder
is  entitled  to the  benefits  of the  Guarantee  Agreement  of AES dated as of
October 29, 1997 (the  "Guarantee")  to the extent provided  therein.  The Trust
will furnish a copy of the  Declaration,  the Guarantee and the Indenture to the
Holder without charge upon written  request to the Trust at its principal  place
of business or registered office.

         The Holder of this  Certificate,  by  accepting  this  Certificate,  is
deemed  to have (i)  agreed to the terms of the  Indenture  and the  Debentures,
including that the Debentures are  subordinate and junior in right of payment to
all Senior and  Subordinated  Debt (as defined in the  Indenture)  as and to the
extent  provided in the Indenture and (ii) agreed to the terms of the Guarantee,
including  that the Guarantee is  subordinate  and junior in right of payment to
all other liabilities of AES, including the Debentures,  and ranks pari passu in
right payment with the most senior preferred stock issued, from time to time, by
AES.

         Upon  receipt  of  this  certificate,   the  Holder  is  bound  by  the
Declaration and is entitled to the benefits thereunder.

         Unless the Property Trustee's  Certificate of Authentication hereon has
been properly executed,  these Trust Preferred  Securities shall not be entitled
to any benefit under the Declaration or be valid or obligatory for any purpose.

                          [FORM OF REVERSE OF SECURITY]

         Distributions  payable on each  Preferred  Security  will be fixed at a
rate per  annum of $2.75 per  Preferred  Security,  such rate  being the rate of
interest  payable  on  the  Debentures  to be  held  by  the  Property  Trustee.
Distributions in arrears for more than one quarter will bear interest thereon at
the rate per annum of 5.50% thereof (to the extent  permitted by law) compounded
quarterly. The term "Distributions" as used herein means such cash distributions
and any such interest payable unless otherwise stated. A Distribution is payable
only to the extent that payments are made in respect of the  Debentures  held by
the Property Trustee. The amount of Distributions payable for any period will be
computed on the basis of a 360-day year of twelve 30-day months.

         Except as otherwise  described  below,  distributions  on the Preferred
Securities  will be  cumulative,  will accrue from  October 29, 1997 and will be
payable  quarterly in arrears,  on the last day of each  quarter,  commencing on
December 31, 1997, but only if and to the extent that interest payments are made
in respect of the Debentures held by the Property Trustee.  So long as AES shall
not be in default in the  payment of  interest  on the  Debentures,  AES has the
right under the  Indenture for the  Debentures to defer  payments of interest by
extending the interest  payment period from time to time on the Debentures for a
period not exceeding 20 consecutive  quarters (each an "Extension  Period") and,
as a consequence,  quarterly Distributions will continue to accrue with interest
thereon (to the extent  permitted  by  applicable  law) at the rate of 5.50% per
annum,  compounded  quarterly  during such  Extension  period;  provided that no
Extension  Period shall last beyond the date of maturity or any redemption  date
of the Debentures.  Prior to the termination of any such Extension  Period,  AES
may  commence  a new  Extension  Period;  provided  that such  Extension  Period
together with all such previous and further extensions thereof may not exceed 20
consecutive  quarterly interest periods.  Payments of accrued Distributions will
be payable to  Holders as they  appear on the books and  records of the Trust on
the  first  record  date  after  the  end  of the  Extension  Period.  Upon  the
termination of any Extension Period and the payment of all amounts then due, AES
may commence a new Extension Period, subject to the above requirements.

         The  Preferred  Securities  shall  be  redeemable  as  provided  in the
Declaration.

         The Preferred  Securities  shall be  convertible  into shares of Common
Stock,  through (i) the  exchange of Preferred  Securities  for a portion of the
Debentures  and (ii) the  immediate  conversion of such  Debentures  into Common
Stock, in the manner and according to the terms set forth in the Declaration.

forth as  Exhibit  B to the  Declaration)  and  (ii)  immediately  convert  such

                           ACCREDITED INVESTOR LETTER

                  , 199



The First National Bank of Chicago
One First National Plaza
Chicago, Illinois 60670-0126

Dear Sirs:

         In connection  with our proposed  purchase of the Preferred  Securities
described below (the "Preferred  Securities") of AES Trust II (the "Issuer"), we
confirm that:

         1.   We have received a copy of the Offering  Memorandum (the "Offering
              Memorandum"),  dated  October 24, 1997,  relating to the Preferred
              Securities and the  undersigned  agrees to be bound by, and not to
              resell,  pledge or  otherwise  transfer the  Preferred  Securities
              except in compliance  with, such  restrictions  and conditions and
              the Securities Act of 1933, as amended (the "Securities Act").

         2.   We  understand  that  any  subsequent  transfer  of the  Preferred
              Securities is subject to certain  restrictions  and conditions set
              forth in the Amended and Restated Declaration of Trust dated as of
              October 29,  1997 (the  "Declaration")  relating to the  Preferred
              Securities and the  undersigned  agrees to be bound by, and not to
              resell,  pledge or  otherwise  transfer the  Preferred  Securities
              except in compliance  with, such  restrictions  and conditions and
              the Securities Act of 1933, as amended (the "Securities Act").

         3.   We  understand  that  the  offer  and the  sale  of the  Preferred
              Securities has not been  registered  under the Securities Act, and
              that the Preferred Securities may not be offered or sold except as
              permitted in the following  sentence.  We agree, on our own behalf
              and  on  behalf  of any  accounts  for  which  we  are  acting  as
              hereinafter   stated,   that  if  we  should  sell  any  Preferred
              Securities or, if applicable,  the Junior Subordinated  Debentures
              or Common  Stock  (together,  the  "Securities")  within two years
              after the original issuance of the Preferred  Securities,  we will
              do so  only  (A) to The AES  Corporation  (the  "Company")  or any
              subsidiary  thereof,  (B) inside the United  States in  accordance
              with  Rule  144A  under  the   Securities   Act  to  a  "qualified
              institutional buyer" (as defined therein), (C) inside the



                                       14
<PAGE>


              United  States  to  an  institutional  "accredited  investor"  (as
              defined  below)  that,  prior to such  transfer,  furnishes to the
              Trustee a signed letter  containing  certain  representations  and
              agreements  relating  to  the  restrictions  on  transfer  of  the
              Preferred  Securities  (the form of which  letter can be  obtained
              from the Trustee) and, if such transfer is in respect of Preferred
              Securities with an aggregate  liquidation  preference of less than
              $250,000,  an opinion of counsel  acceptable  to the Company  that
              such  transfer  is in  compliance  with the  Securities  Act,  (D)
              outside the United  States in  accordance  with the Rule 904 under
              the Securities Act (E) pursuant to the exemption from registration
              provided by Rule 144 under the  Securities  Act (if  available) or
              (F)  pursuant to an  effective  registration  statement  under the
              Securities  Act,  and we  further  agree to  provide to any person
              purchasing  any of  the  Preferred  Securities  from  us a  notice
              advising such purchaser  that resales of the Preferred  Securities
              are restricted as stated herein.

         4.   We understand  that, on any proposed resale of any Securities,  we
              will be  required  to furnish to the Issuer and the  Trustee  such
              certifications, legal opinions and other information as the Issuer
              and the  Trustee  may  reasonably  require  to  confirm  that  the
              proposed sale complies with the foregoing restrictions. We further
              understand that the Securities  purchased by us will bear a legend
              to the foregoing effect.

         5.   We are a institutional  "accredited  investor" (as defined in rule
              501(a)(1),  (2), (3) or (7) of  Regulation D under the  Securities
              Act) and have such  knowledge  and  experience  in  financial  and
              business  matters as to be capable  of  evaluating  the merits and
              risks of our  investment in the Preferred  Securities,  and we and
              any  accounts  for which we are  acting  are each able to bear the
              economic risks of our or their investment.

         6.   We are acquiring the Preferred  Securities purchased by us for our
              own  account  for  one or  more  accounts  (each  of  which  is an
              institutional  "accredited  investor")  as to  each  of  which  we
              exercise sole investment discretion.

                                                                       EXHIBIT C


                                    TERMS OF
                                COMMON SECURITIES


         Pursuant to Section  7.01 of the Amended and  Restated  Declaration  of
Trust of AES Capital Trust II dated as of October 29, 1997 (as amended from time
to time, the "Declaration"), the designations, rights, privileges, restrictions,
preferences  and other terms and  provisions  of the Common  Securities  are set
forth  below  (each  capitalized  term used but not  defined  herein  having the
meaning set forth in the Declaration):

         1.  DESIGNATION  AND  NUMBER.  Common  Securities  of the Trust with an
aggregate  liquidation  amount in the  assets of the Trust of Nine  Million  Two
Hundred Seventy-Eight  Thousand Three Hundred Fifty Dollars ($9,278,400 (plus up
to an additional  One Million Three Hundred  Ninety-One  Thousand  Seven Hundred
Fifty Dollars  ($1,391,800)  issuable upon exercise of the overallotment  option
set forth in the Purchase  Agreement) and a liquidation  amount in the assets of
the Trust of $50 per Common  Security,  are hereby  designated  as "$2.75 Common
Trust  Securities".  The  Common  Security  Certificates  evidencing  the Common
Securities  shall be  substantially in the form attached hereto as Annex I, with
such changes and additions thereto or deletions  therefrom as may be required by
ordinary usage,  custom or practice.  The Common Securities are to be issued and
sold to The AES Corporation  ("AES") in  consideration of $9,278,400 in cash. In
connection with the issuance and sale of the Preferred Securities and the Common
Securities,  the Trust will purchase as trust assets Debentures of AES having an
aggregate  principal  amount equal to the  aggregate  liquidation  amount of the
Preferred Securities and Common Securities so issued, and bearing interest at an
annual rate equal to the annual  Distribution  rate on the Preferred  Securities
and Common  Securities  and  having  payment  and  redemption  provisions  which
correspond to the payment and redemption  provisions of the Preferred Securities
and Common Securities.

         2.  DISTRIBUTIONS.  (a)  Distributions  payable on each Common Security
will be fixed  at a rate per  annum of $2.75  (the  "Coupon  Rate")  per  Common
Security.  Distributions in arrears for more than one calendar quarter will bear
interest  at the rate per annum of 5.50%  thereof  (to the extent  permitted  by
applicable law), compounded quarterly. The term "Distributions" as used in these
terms means such  periodic  cash  distributions  and any such  interest  payable
unless  otherwise  stated.  A Distribution  will be made by the Property Trustee
only to the extent that interest  payments are made in respect of the Debentures
held by the Property Trustee. The amount of





                                       
<PAGE>


Distributions   payable  for  any  period  will  be  computed  for  any  monthly
Distribution period on the basis of a 360-day year of twelve 30 day months.

         (b)  Distributions  on the Common  Securities will be cumulative,  will
accrue from October 29, 1997 and will be payable  quarterly  in arrears,  on the
last day of each month  commencing  on December  31,  1997,  except as otherwise
described below,  but only if and to the extent that interest  payments are made
in respect of the Debentures held by the Property Trustee.  So long as AES shall
not be in default in the  payment of  interest  on the  Debentures,  AES has the
right under the  Indenture for the  Debentures to defer  payments of interest by
extending the interest  payment period from time to time on the Debentures for a
period not  exceeding  20  consecutive  quarterly  interest  periods  (each,  an
"Extension Period") and, as a consequence, quarterly Distributions will continue
to accrue with interest  thereon (to the extent  permitted by applicable law) at
the rate of 5.50% per annum,  compounded  quarterly  during  any such  Extension
Period; provided that no Extension Period shall last beyond the date of maturity
or any redemption date of the  Debentures.  Prior to the termination of any such
Extension Period,  AES may further extend such Extension  Period;  provided that
such  Extension  Period  together with all such previous and further  extensions
thereof  may not exceed 20  consecutive  quarterly  interest  periods.  Upon the
termination of any Extension Period and the payment of all amounts then due, AES
may commence a new Extension Period, subject to the above requirements. Payments
of accrued Distributions will be payable to Holders of Common Securities as they
appear on the books and records of the Trust on the first  record date after the
end of the Extension Period.

         (c)  Distributions on the Common Securities will be payable promptly by
the  Property  Trustee  (or other  Paying  Agent)  upon  receipt of  immediately
available  funds to the Holders  thereof as they appear on the books and records
of the Trust on the  relevant  record dates which will be one business day prior
to the relevant  Distribution date unless the Preferred Securities are no longer
in book-entry only form in which event the Regular Trustees shall have the right
to select  relevant record dates which shall be more than one business day prior
to the relevant payment dates.  Distributions  payable on any Common  Securities
that are not punctually paid on any Distribution  date as a result of AES having
failed  to make  the  corresponding  interest  payment  on the  Debentures  will
forthwith  cease to be payable to the person in whose name such Common  Security
is registered on the relevant record date, and such defaulted  Distribution will
instead  be  payable  to the  person  in whose  name  such  Common  Security  is
registered on the special record date established by the Regular Trustees, which
record date shall  correspond to the special record date or other specified date
determined  in  accordance   with  the  Indenture;   provided,   however,   that
Distributions  shall not be considered payable on any Distribution  payment date
falling  within an  Extension  Period  unless AES has  elected to make a full or
partial  payment of  interest  accrued on the  Debentures  on such  Distribution
payment date. Subject to any





                                       2
<PAGE>


applicable  laws and  regulations  and the provisions of the  Declaration,  each
payment  in  respect  of the  Common  Securities  will be made as  described  in
paragraph  10  hereof.  If any date on which  Distributions  are  payable on the
Common  Securities  is not a Business  Day,  then  payment  of the  Distribution
payable on such date will be made on the next  succeeding day that is a Business
Day (and  without any  interest  or other  payment in respect of any such delay)
except that, if such Business Day is in the next succeeding  calendar year, such
payment shall be made on the  immediately  preceding  Business Day, in each case
with the same force and effect as if made on such date.

         (d) All  Distributions  paid with respect to the Common  Securities and
the Preferred  Securities will be paid Pro Rata to the Holders thereof  entitled
thereto.  If an Event of Default has occurred and is  continuing,  the Preferred
Securities  shall have a priority  over the Common  Securities  with  respect to
Distributions.

         (e) In the event of an election by the Holder to convert its Securities
through  the  Conversion  Agent into Common  Stock  pursuant to the terms of the
Securities  as set  forth in this  Exhibit  C to the  Declaration,  no  payment,
allowance or  adjustment  shall be made with respect to  accumulated  and unpaid
Distributions on such Securities, or be required to be made; provided,  however,
that if a Security is surrendered for conversion  after the close of business on
any regular record date for payment of a Distribution  date will be paid in cash
to the person in whose name the Security is  registered at the close of business
on such  record  date,  and (other  than a  Security  or a portion of a Security
called for redemption on a redemption  date occurring after such record date and
on or prior to such Distribution  date) when so surrendered for conversion,  the
Security must be accompanied  by payment of an amount equal to the  Distribution
payable on such Distribution date.

         (f) In the event that there is any money or other  property  held by or
for the Trust that is not  accounted  for under the  Declaration,  such money or
property  shall be  distributed  Pro Rata  among the  Holders  of the  Preferred
Securities and Common Securities.

         3.  LIQUIDATION  DISTRIBUTION  UPON  DISSOLUTION.  In the  event of any
voluntary or  involuntary  dissolution,  winding-up or termination of the Trust,
the Holders of the Preferred Securities and Common Securities at the date of the
dissolution,  winding-up or termination, as the case may be, will be entitled to
receive  Pro  Rata  solely  out  of  the  assets  of  the  Trust  available  for
distribution  to Holders of Preferred  Securities and Common  Securities,  after
satisfaction  of liabilities  to creditors,  an amount equal to the aggregate of
the stated  liquidation amount of $50 per Preferred Security and Common Security
plus  accrued  and unpaid  Distributions  thereon  to the date of payment  (such
amount being the "Liquidation  Distribution"),  unless,  in connection with such
dissolution, winding-up or termination, and after




                                       3
<PAGE>


satisfaction of liabilities to creditors,  Debentures in an aggregate  principal
amount  equal to the  aggregate  stated  liquidation  amount  of such  Preferred
Securities  and Common  Securities  bearing  accrued  and unpaid  interest in an
amount  equal  to the  accrued  and  unpaid  Distributions  on,  such  Preferred
Securities and Common  Securities,  shall be distributed Pro Rata to the Holders
of  the  Preferred  Securities  and  Common  Securities  in  exchange  for  such
Securities.

         If, upon any such dissolution, the Liquidation Distribution can be paid
only in part because the Trust has insufficient  assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the Preferred  Securities and Common Securities shall be paid,  subject
to the next paragraph, on a Pro Rata basis.

         Holders of Common  Securities  will be entitled to receive  Liquidation
Distributions  upon any such  dissolution  Pro Rata with  Holders  of  Preferred
Securities,  except that if an Event of Default has occurred and is  continuing,
the Preferred  Securities shall have a priority over the Common  Securities with
respect to such Liquidation Distribution.

         4. REDEMPTION AND DISTRIBUTION OF DEBENTURES.  The Preferred Securities
and Common  Securities  may only be redeemed if  Debentures  having an aggregate
principal  amount equal to the  aggregate  liquidation  amount of the  Preferred
Securities  and Common  Securities  are repaid,  redeemed or  distributed as set
forth below:

         (a) Upon the repayment of the Debentures,  in whole or in part, whether
at  maturity,  upon  redemption  at any  time or from  time to time on or  after
September 30, 2000, or at any time in certain  circumstances upon the occurrence
of a Tax Event,  the  proceeds of such  repayment  will be  promptly  applied to
redeem Pro Rata Preferred  Securities and Common  Securities having an aggregate
liquidation amount equal to the aggregate  principal amount of the Debentures so
repaid or redeemed,  upon not less than 30 nor more than 60 days'  notice,  at a
redemption price per Preferred and Common Security equal to the redemption price
of the  Debentures,  together  with  accrued  and unpaid  Distributions  thereon
through the date of redemption,  payable in cash (the "Redemption  Price").  The
date of any such  repayment or  redemption  of Preferred  Securities  and Common
Securities  shall be  established  to coincide  with the repayment or redemption
date of the Debentures.

         (b) If fewer than all the outstanding  Preferred  Securities and Common
Securities  are to be so  redeemed,  the  Preferred  Securities  and the  Common
Securities  will be redeemed Pro Rata and the Common  Securities  to be redeemed
will be  redeemed  as  described  in  paragraph  4(e)(ii)  below.  If a  partial
redemption  would result in the  delisting of the  Preferred  Securities  by any
national  securities  exchange  or other  organization  on which  the  Preferred
Securities are then listed, AES pursuant





                                       4
<PAGE>


to the  Indenture  will only redeem  Debentures  in whole and, as a result,  the
Trust may only redeem the Common Securities in whole.

         (c) If, at any time, a Tax Event or an  Investment  Company Event (each
as  hereinafter  defined,  and  each  a  "Special  Event")  shall  occur  and be
continuing,  the Regular  Trustees shall,  unless the Debentures are redeemed in
the  limited  circumstances  described  below,  dissolve  the Trust  and,  after
satisfaction of creditors,  cause Debentures held by the Property Trustee having
an aggregate  principal amount equal to the aggregate stated  liquidation amount
of and accrued and unpaid interest equal to accrued and unpaid Distributions on,
and having the same  record  date for payment as the  Preferred  Securities  and
Common Securities,  to be distributed to the Holders of the Preferred Securities
and  Common  Securities  on a Pro Rata  basis in  liquidation  of such  Holders'
interests in the Trust,  within 90 days following the occurrence of such Special
Event  (the  "90  Day  Period");  provided,  however,  that  in the  case of the
occurrence of a Tax Event, as a condition of such dissolution and  distribution,
the Regular  Trustees shall have received an opinion of a nationally  recognized
independent  tax  counsel   experienced  in  such  matters  (a  "No  Recognition
Opinion"),  which  opinion  may rely on any then  applicable  published  revenue
rulings of the Internal Revenue  Service,  to the effect that the Holders of the
Preferred  Securities  will not  recognize  any gain or loss for  United  States
federal  income tax  purposes  as a result of the  dissolution  of the Trust and
distribution of Debentures;  and provided,  further,  that, if and as long as at
the time there is available to the Trust the  opportunity  to eliminate,  within
such 90 Day Period, the Special Event by taking some ministerial action, such as
filing a form or making an election,  or pursuing some other similar  reasonable
measure  that has no  adverse  effect on the  Trust,  AES or the  Holders of the
Preferred Securities  ("Ministerial  Action") the Trust will pursue such measure
in lieu of dissolution.

         If in the  case of the  occurrence  of a Tax  Event,  (i)  the  Regular
Trustees  have  received an opinion (a  "Redemption  Tax Opinion") of nationally
recognized independent tax counsel experienced in such matters that, as a result
of a Tax  Event,  there is more  than an  insubstantial  risk  that AES would be
precluded  from  deducting  the  interest on the  Debentures  for United  States
federal  income tax purposes  even if the  Debentures  were  distributed  to the
Holders of Preferred  Securities  and Common  Securities in  liquidation of such
Holder's  interest in the Trust as described in this  paragraph 4(c) or (ii) the
Regular  Trustees  shall  have  been  informed  by such  tax  counsel  that a No
Recognition  Opinion cannot be delivered to the Trust,  AES shall have the right
at any time, upon not less than 30 nor more than 60 days' notice,  to redeem the
Debentures in whole or in part for cash at the  Redemption  Price within 90 days
following  the  occurrence  of such  Tax  Event,  and  promptly  following  such
redemption   Preferred  Securities  and  Common  Securities  with  an  aggregate
liquidation amount equal to the aggregate  principal amount of the Debentures so
redeemed  will be  redeemed by the Trust at the  Redemption  Price on a Pro Rata
basis: provided,




                                       5
<PAGE>


however,  that, if at the time there is available to AES or the Regular Trustees
on behalf of the Trust the opportunity to eliminate,  within such 90 day period,
the Tax Event by taking  some  Ministerial  Action,  AES or the  Holders  of the
Preferred  Securities,  AES or the Regular  Trustees on behalf of the Trust will
pursue such measure in lieu of redemption; and provided, further, that AES shall
have no right to redeem the Debentures  while the Regular  Trustees on behalf of
the Trust are pursuing such Ministerial  Action.  The Common  Securities will be
redeemed  Pro Rata with the  Preferred  Securities,  except  that if an Event of
Default  under the  Indenture  has occurred  and is  continuing,  the  Preferred
Securities  will have a priority  over the  Common  Securities  with  respect to
payment of the Redemption Price.

         "Tax Event"  means that the  Regular  Trustees  shall have  obtained an
opinion of nationally  recognized  independent  tax counsel  experienced in such
matters (a "Dissolution Tax Opinion") to the effect that on or after October 23,
1997 as a result of (a) any  amendment  to, or change  (including  any announced
prospective  change) in, the laws (or any regulations  thereunder) of the United
States or any political  subdivision or taxing authority thereof or therein, (b)
any amendment to, or change in, an  interpretation  or  application  of any such
laws or regulations  by any  legislative  body,  court,  governmental  agency or
regulatory  authority  (including  the  enactment  of any  legislation  and  the
publication  of any  judicial  decision or  regulatory  determination),  (c) any
interpretation  or  pronouncement  that  provides for a position with respect to
such laws or regulations  that differs from the theretofore  generally  accepted
position  or (d) any  action  taken by any  governmental  agency  or  regulatory
authority,  which  amendment  or  change  is  enacted,  promulgated,  issued  or
announced or which  interpretation  or  pronouncement  is issued or announced or
which action is taken, in each case on or after October 23, 1997,  there is more
than an  insubstantial  risk that (i) the Trust is, or will be within 90 days of
the date thereof,  subject to United States  federal  income tax with respect to
income  accrued or  received  on the  Debentures,  (ii) the Trust is, or will be
within 90 days of the date thereof,  subject to more than a de minimis amount of
taxes, duties or other governmental  charges or (iii) interest payable by AES to
the Trust on the  Debentures  is not, or within 90 days of the date thereof will
not be, deductible by AES for United States federal income tax purposes.

         "Investment  Company Event" means that the Regular  Trustees shall have
received an opinion of nationally recognized  independent counsel experienced in
practice under the Investment Company Act that, as a result of the occurrence of
a change in law or regulation or a change in  interpretation  or  application of
law or  regulation  by any  legislative  body,  court,  governmental  agency  or
regulatory  authority  (a  "Change  in 1940 Act  Law"),  there  is more  than an
insubstantial risk that the Trust is or will be considered an Investment Company
which is required to be  registered  under the  Investment  Company  Act,  which
Change in 1940 Act Law becomes effective on or after October 23, 1997.





                                       6

         On the date fixed for any distribution of Debentures,  upon dissolution
of the  Trust,  (i)  the  Common  Securities  will no  longer  be  deemed  to be
outstanding and (ii) any  certificates  representing  Common  Securities will be
deemed to represent  beneficial  interests in the Debentures having an aggregate
principal amount equal to the stated  liquidation amount of, and bearing accrued
and unpaid  interest equal to accrued and unpaid  Distributions  on, such Common
Securities  until  such  certificates  are  presented  to AES or its  agent  for
transfer or reissuance.

         (d) The Trust may not redeem any outstanding  Common  Securities unless
all accrued and unpaid Distributions have been paid on all Common Securities for
all  quarterly  Distribution  periods  terminating  on or  prior  to the date of
redemption.

         (e)(i)  Notice of any  redemption  of, or  notice  of  distribution  of
Debentures in exchange for, the Preferred  Securities  and Common  Securities (a
"Redemption/  Distribution  Notice")  will be given by the  Regular  Trustees on
behalf of the Trust by mail to each Holder of  Preferred  Securities  and Common
Securities  to be redeemed or  exchanged  not less than 30 nor more than 60 days
prior to the date fixed for redemption or exchange thereof.  For purposes of the
calculation of the date of redemption or exchange and the dates on which notices
are given pursuant to this paragraph  (e)(i), a  Redemption/Distribution  Notice
shall  be  deemed  to be  given  on the day  such  notice  is  first  mailed  by
first-class mail, postage prepaid, to Holders of Preferred Securities and Common
Securities.  Each  Redemption/Distribution  Notice  shall  be  addressed  to the
Holders of Preferred  Securities  and Common  Securities  at the address of each
such Holder  appearing  in the books and records of the Trust.  No defect in the
Redemption/Distribution  Notice or in the mailing of either thereof with respect
to  any  Holder  shall  affect  the  validity  of  the  redemption  or  exchange
proceedings with respect to any other Holder.

         (ii) In the event that fewer than all the outstanding Common Securities
are to be redeemed,  the Common  Securities  to be redeemed will be redeemed Pro
Rata from each Holder of Common  Securities  (subject to adjustment to eliminate
fractional Common Securities).

         (iii) If the Trust gives a Redemption/Distribution Notice in respect of
a redemption of Common  Securities as provided in this paragraph 4 (which notice
will be  irrevocable)  then  immediately  prior to the close of  business on the
redemption  date,  provided  that  AES  has  paid  to the  Property  Trustee  in
immediately  available funds a sufficient  amount of cash in connection with the
related  redemption or maturity of the Debentures,  Distributions  will cease to
accrue on the Common  Securities  called for redemption,  such Common Securities
will no longer be deemed to be  outstanding  and all  rights of  Holders of such
Common  Securities so called for redemption will cease,  except the right of the
Holders of such Common  Securities to receive the Redemption  Price, but without
interest on such Redemption Price.




                                       7
<PAGE>


Neither the  Trustees nor the Trust shall be required to register or cause to be
registered the transfer of any Common  Securities  which have been so called for
redemption.  If any date  fixed for  redemption  of Common  Securities  is not a
Business Day, then payment of the Redemption  Price payable on such date will be
made on the next succeeding day that is a Business Day (and without any interest
or other payment in respect of any such delay) except that, if such Business Day
falls in the next calendar  year,  such payment will be made on the  immediately
preceding  Business  Day, in each case with the same force and effect as if made
on such date fixed for redemption. If payment of the Redemption Price in respect
of Common  Securities  is  improperly  withheld  or refused  and not paid by the
Property  Trustee,  Distributions  on such Common  Securities  will  continue to
accrue,  from the original redemption date to the date of payment, in which case
the actual  payment date will be considered  the date fixed for  redemption  for
purposes of calculating the Redemption Price.

         (iv)  Redemption/Distribution  Notices  shall  be sent  by the  Regular
Trustees on behalf of the Trust to the Holders of the Common Securities.

         (v) Upon the date of  dissolution  of the  Trust  and  distribution  of
Debentures as a result of the  occurrence of a Special  Event,  Common  Security
Certificates shall be deemed to represent beneficial interests in the Debentures
so distributed,  and the Common Securities will no longer be deemed  outstanding
and may be canceled by the Regular Trustees. The Debentures so distributed shall
have an aggregate principal amount equal to the aggregate  liquidation amount of
the Common Securities so distributed.

         5. CONVERSION RIGHTS. The Holders of Securities shall have the right at
any time prior to the close of business on  September  30, 2012 (or, in the case
of  Securities  called for  redemption,  prior to the close of  business  on the
Business  Day  prior to the  redemption  date),  at their  option,  to cause the
Conversion  Agent to convert  Securities,  on behalf of the converting  Holders,
into shares of Common Stock in the manner described herein on and subject to the
following terms and conditions:

         The  Securities  will be  convertible  at the office of the  Conversion
Agent into fully paid and  nonassessable  shares of Common Stock pursuant to the
Holder's  direction to the  Conversion  Agent to exchange such  Securities for a
portion  of the  Debentures  theretofore  held by the  Trust on the basis of one
Security per $50 principal  amount of Debentures,  and immediately  convert such
amount of Debentures into fully paid and nonassessable shares of Common Stock at
an initial  rate of 0.8914  shares of Common Stock per $50  principal  amount of
Debentures  (which is  equivalent  to a conversion  price of $56.09 per share of
Common Stock, subject to certain adjustments set forth in Sections 5.03 and 5.04
of the Supplemental Indenture (as so adjusted, "Conversion Price")).



                                       8
<PAGE>


         (a) In order to convert  Securities  into Common Stock the Holder shall
submit to the  Conversion  Agent at the office  referred to above an irrevocable
request  to  convert  Securities  on  behalf  of such  Holder  (the  "Conversion
Request"),  together,  if the Securities  are in  certificated  form,  with such
certificates.  The  Conversion  Request  shall  (i)  set  forth  the  number  of
Securities to be converted and the name or names,  if other than the Holder,  in
which the shares of Common Stock should be issued and (ii) direct the Conversion
Agent (a) to exchange such  Securities for a portion of the  Debentures  held by
the Trust (at the rate of exchange specified in the preceding paragraph) and (b)
to  immediately  convert such  Debentures on behalf of such Holder,  into Common
Stock  (at the  conversion  rate  specified  in the  preceding  paragraph).  The
Conversion Agent shall notify the Property  Trustee of the Holder's  election to
exchange  Securities for a portion of the  Debentures  held by the Trust and the
Property Trustee shall,  upon receipt of such notice,  deliver to the Conversion
Agent the appropriate  principal amount of Debentures for exchange in accordance
with this Section.  The  Conversion  Agent shall  thereupon  notify the Property
Trustee of the  Holder's  election  to convert  such  Debentures  into shares of
Common Stock.  If a Security is surrendered  for  conversion  after the close of
business on any regular record date for payment of a Distribution and before the
opening of  business  on the  corresponding  Distribution  payment  date,  then,
notwithstanding  such conversion,  the Distribution payable on such Distribution
payment  date will be paid in cash to the person in whose name the  Security  is
registered  at the close of  business  on such  record  date,  and (other than a
Security or a portion of a Security  called for redemption on a redemption  date
occurring  after such record date and on or prior to such  Distribution  payment
date) when so surrendered  for  conversion,  the Security must be accompanied by
payment of an amount  equal to the  Distribution  payable  on such  Distribution
payment date.  Except as provided above,  neither the Trust nor the Sponsor will
make,  or be required to make,  any payment,  allowance or  adjustment  upon any
conversion on account of any accumulated and unpaid Distributions accumulated on
the Securities surrendered for conversion,  or on account of any accumulated and
unpaid  dividends  on the shares of Common  Stock  issued upon such  conversion.
Securities shall be deemed to have been converted immediately prior to the close
of business on the day on which a Conversion Request relating to such Securities
is  received  by the  Trust in  accordance  with the  foregoing  provision  (the
"Conversion  Date").  The Person or Persons  entitled  to receive  Common  Stock
issuable upon conversion of the Debentures  shall be treated for all purposes as
the record  holder or holders of such Common Stock at such time.  As promptly as
practicable on or after the Conversion Date, the Sponsor shall issue and deliver
at the office of the  Conversion  Agent a certificate  or  certificates  for the
number of full shares of Common Stock  issuable upon such  conversion,  together
with the cash  payment,  if any,  in lieu of any  fraction  of any  share to the
Person or Persons entitled to receive the same, unless otherwise directed by the
Holder in the Conversion  Request and the Conversion Agent shall distribute such
certificate or certificates,  together with the applicable cash payment, if any,
to such Person or Persons.




                                       9

         (b) Each Holder of a Security by his  acceptance  thereof  appoints The
First National Bank of Chicago  "Conversion  Agent" for the purpose of effecting
the conversion of Securities in accordance  with this Section.  In effecting the
conversion and  transactions  described in this Section,  the  Conversion  Agent
shall be acting as agent of the  Holders of  Securities  directing  it to effect
such conversion  transactions.  The Conversion Agent is hereby authorized (i) to
exchange  Securities  from  time to time  for  Debentures  held by the  Trust in
connection  with the  conversion  of such  Securities  in  accordance  with this
section and (ii) to convert all or a portion of the Debentures into Common Stock
and  thereupon  to deliver such shares of Common  Stock in  accordance  with the
provisions  of this  section  and to  deliver  to the Trust a new  Debenture  or
Debentures for any resulting unconverted principal amount.

         (c) No fractional  shares of Common Stock will be issued as a result of
conversion,  but in lieu thereof,  such fractional interest will be paid in cash
by the Company to the Conversion Agent,  which in turn will make such payment to
the Holder or Holders of Securities so converted.

         (d) The Sponsor  shall at all times  reserve and keep  available out of
its  authorized  and  unissued  Common  Stock,  solely  for  issuance  upon  the
conversion of the Debentures,  free from any preemptive or other similar rights,
such  number of shares of Common  Stock as shall  from time to time be  issuable
upon the conversion of all the Debentures then outstanding.  Notwithstanding the
foregoing, shall be entitled to deliver upon conversion of Debentures, shares of
Common Stock  reacquired and held in the treasury of the Sponsor (in lieu of the
issuance of authorized and unissued shares of Common Stock), so long as any such
treasury shares are free and clear of all liens, charges,  security interests or
encumbrances.  Any  shares  of  Common  Stock  issued  upon  conversion  of  the
Debentures  shall  be  duly  authorized,  validly  issued  and  fully  paid  and
nonassessable.  The Trust shall deliver the shares of Common Stock received upon
conversion  of the  Debentures  to the  converting  Holder free and clear of all
liens,  charges,  security interests and encumbrances,  except for United States
withholding taxes. Each of the Sponsor and the Trust shall prepare and shall use
its best  efforts to obtain and keep in force such  governmental  or  regulatory
permits or other authorizations as may be required by law, and shall comply with
all applicable  requirements as to registration or qualification of Common Stock
(and  all  requirements  to  list  Common  Stock  issuable  upon  conversion  of
Debentures that are at the time  applicable),  in order to enable the company to
lawfully  issue Common Stock to the Trust upon  conversion of the Debentures and
the Trust to lawfully deliver Common Stock to each Holder upon conversion of the
Securities.

         (e) The  Sponsor  will pay any and all  taxes  that may be  payable  in
respect of the issue or  delivery  of shares of Common  Stock on  conversion  of
Debentures  and the  delivery  of the  shares of Common  Stock by the Trust upon
conversion of the Securities. The Sponsor shall not, however, be required to pay
any tax which may be



                                       10
<PAGE>


payable in respect of any transfer  involved in the issue and delivery of shares
of Common Stock in a name other than that in which the  Securities  so converted
were  registered,  and no such issue or delivery  shall be made unless and until
the  person  requesting  such issue has paid to the Trust the amount of any such
tax, or has established to the  satisfaction of the Trust that such tax has been
paid.

         (f) Nothing in the preceding  Paragraph (e) shall limit the requirement
of the Trust to withhold  taxes  pursuant to the terms of the  Securities or set
forth in this  Exhibit  C to the  Declaration  or to the  Declaration  itself or
otherwise  require  the  Property  Trustee  or the Trust to pay any  amounts  on
account of such withholdings.

         6. VOTING RIGHTS. (a) Except as provided under paragraph 5(b) below and
as  otherwise  required  by law and the  Declaration,  the Holders of the Common
Securities will have no voting rights.

         (b)  Holders  of  Common  Securities  have the  sole  right  under  the
Declaration  to  increase or decrease  the number of  Trustees,  and to appoint,
remove or replace a Trustee, any such increase, decrease,  appointment,  removal
or  replacement  to be approved by Holders of Common  Securities  representing a
Majority in liquidation amount of the Common Securities.

         If any  proposed  amendment  to the  Declaration  provides  for, or the
Regular  Trustees  otherwise  propose  to  effect,  (i) any  action  that  would
adversely  affect the powers,  preferences or special rights of the  Securities,
whether  by way of  amendment  to the  Declaration  or  otherwise,  or (ii)  the
dissolution,  winding-up or termination  of the Trust,  other than in connection
with the  distribution  of  Debentures  held by the Property  Trustee,  upon the
occurrence  of a Special Event or in  connection  with the  redemption of Common
Securities as a consequence of a redemption of  Debentures,  then the Holders of
outstanding Securities will be entitled to vote on such amendment or proposal as
a class and such  amendment or proposal  shall not be effective  except with the
approval of the Holders of  Securities  representing  a Majority in  liquidation
amount of such  Securities;  provided,  however,  that (A) if any  amendment  or
proposal  referred  to in  clause  (i) above  would  adversely  affect  only the
Preferred Securities or the Common Securities, then only the affected class will
be entitled to vote on such amendment or proposal and such amendment or proposal
shall not be  effective  except with the  approval of a Majority in  liquidation
amount  of such  class of  Securities,  (B) the  rights  of  Holders  of  Common
Securities  under  Article 4.02 of the  Declaration  to increase or decrease the
number of, and to  appoint,  replace  or remove,  Trustees  shall not be amended
without the consent of each Holder of Common  Securities,  and (C) amendments to
the Declaration  shall be subject to such further  requirements as are set forth
in Sections 12.01 and 12.02 of the Declaration.






                                       11
<PAGE>


         In the event the consent of the  Property  Trustee as the holder of the
Debentures,  is required  under the  Indenture  with  respect to any  amendment,
modification  or  termination of the Indenture or the  Debentures,  the Property
Trustee  shall  request the written  direction of the Holders of the  Securities
with  respect to such  amendment,  modification  or  termination.  The  Property
Trustee shall vote with respect to such  amendment,  modification or termination
as  directed  by a  Majority  in  liquidation  amount of the  Securities  voting
together as a single class; provided that where such amendment,  modification or
termination  of the  Indenture  requires  the  consent or vote of (1) holders of
Debentures  representing  a  specified  percentage  greater  than a majority  in
principal  amount  of the  Debentures  or (2) each  holder  of  Debentures,  the
Property  Trustee may only vote with respect to that amendment,  modification or
termination as directed by, in the case of clause (1) above, the vote of Holders
of  Securities   representing   such  specified   percentage  of  the  aggregate
liquidation amount of the Securities,  or, in the case of clause (2) above, each
Holder of Securities; and provided,  further, that the Property Trustee shall be
under no obligation to take any action in accordance  with the directions of the
Holders of the Securities  unless the Property  Trustee shall have received,  at
the expense of the Sponsor, an opinion of nationally recognized  independent tax
counsel  recognized  as an expert in such  matters to the effect  that the Trust
will not be  classified  for United  States  federal  income tax  purposes as an
association  taxable as a corporation or a partnership on account of such action
and will be treated  as a grantor  trust for United  States  federal  income tax
purposes following such action.

         Subject to Section 2.06 of the Declaration,  and the provisions of this
and the next  succeeding  paragraph,  the Holders of a Majority  in  liquidation
amount of the Common  Securities,  voting  separately  as a class shall have the
right to (A) on  behalf of all  Holders  of  Common  Securities,  waive any past
default that is waivable  under the  Declaration  (subject to, and in accordance
with the Declaration) and (B) direct the time,  method,  and place of conducting
any proceeding for any remedy available to the Property  Trustee,  or exercising
any trust or power  conferred upon the Property  Trustee under the  Declaration,
including the right to direct the Property Trustee, as holder of the Debentures,
to (i) direct the time,  method and place of conducting  any  proceeding for any
remedy  available to the Debenture  Trustee,  or  exercising  any trust or power
conferred on the Debenture  Trustee with respect to the  Debentures,  (ii) waive
any past default and its consequences that is waivable under Section 6.06 of the
Indenture,  or (iii)  exercise any right to rescind or annul a declaration  that
the  principal of all the  Debentures  shall be due and payable;  provided  that
where the taking of any action under the Indenture  requires the consent or vote
of (1) holders of Debentures  representing a specified percentage greater than a
majority in principal amount of the Debentures or (e) each holder of Debentures,
the  Property  Trustee may only take such action if directed  by, in the case of
clause (1) above,  the vote of Holders of Common  Securities  representing  such
specified  percentage  of  the  aggregate   liquidation  amount  of  the  Common
Securities, or, in the case of clause (2) above, each Holder of Common





                                       12
<PAGE>


Securities.  Pursuant to this paragraph,  the Property Trustee shall not revoke,
or take any action  inconsistent  with,  any  action  previously  authorized  or
approved by a vote of the  Holders of the  Preferred  Securities,  and shall not
take any action in  accordance  with the  direction of the Holders of the Common
Securities  under this  paragraph if the action is prejudicial to the Holders of
Preferred Securities.  Other than with respect to directing the time, method and
place of  conducting  any  proceeding  for any remedy  available to the Property
Trustee or the Debenture  Trustee as set forth above, the Property Trustee shall
be under no obligation to take any of the foregoing  actions at the direction of
the  Holders of Common  Securities  unless  the  Properties  Trustee  shall have
received,  at the expense of the Sponsor,  an opinion of  nationally  recognized
independent tax counsel  recognized as expert in such matters to the effect that
the Trust will not be classified  for United States  federal income tax purposes
as an  association  taxable as a corporation or a partnership on account of such
action  and will be  treated as a grantor  trust for  United  States  income tax
purposes following such action.

         Notwithstanding  any other  provision  of these  terms,  each Holder of
Common  Securities  will be deemed to have  waived  any  Event of  Default  with
respect  to the  Common  Securities  and its  consequences  until all  Events of
Default with respect to the Preferred  Securities have been cured, waived by the
Holders of  Preferred  Securities  as provided in the  Declaration  or otherwise
eliminated,  and until all  Events of  Default  with  respect  to the  Preferred
Securities have been so cured, waived by the Holders of Preferred  Securities or
otherwise eliminated, the Property Trustee will be deemed to be acting solely on
behalf of the  Holders  of  Preferred  Securities  and only the  Holders  of the
Preferred  Securities  will have the right to direct  the  Property  Trustee  in
accordance with the terms of the Declaration or of the Securities.  In the event
that any Event of Default with respect to the Preferred  Securities is waived by
the Holders of Preferred Securities as provided in the Declaration,  the Holders
of Common  Securities agree that such waiver shall also constitute the waiver of
such Event of Default  with  respect to the Common  Securities  for all purposes
under the Declaration without any further act, vote or consent of the Holders of
the Common Securities.

         A waiver of an Indenture  Event of Default by the  Property  Trustee at
the  direction  of the Holders of the  Preferred  Securities  will  constitute a
waiver of the corresponding Event of Default under the Declaration in respect of
the Securities.

         Any required approval of Holders of Common Securities may be given at a
separate meeting of Holders of Common Securities convened for such purpose, at a
meeting of all of the Holders of  Securities of the Trust or pursuant to written
consent.  The  Regular  Trustees  will  cause a notice of any  meeting  at which
Holders of Common  Securities  are entitled to vote, or of any matter upon which
action by written  consent of such Holders is to be taken,  to be mailed to each
Holder of record of Common Securities. Each such notice will include a statement
setting forth (i) the date of such





                                       13
<PAGE>


meeting or the date by which such action is to be taken,  (ii) a description  of
any  resolution  proposed for adoption at such meeting on which such Holders are
entitled  to vote or of such  matter  upon which  written  consent is sought and
(iii) instructions for the delivery of proxies or consents.

         No vote or consent of the Holders of Common Securities will be required
for the Trust to redeem and cancel  Common  Securities  in  accordance  with the
Declaration.

         7.  PRO RATA  TREATMENT.  A  reference  in  these  terms of the  Common
Securities to any payment,  distribution  or treatment as being "Pro Rata" shall
mean  pro  rata  to  each  Holder  of  Securities  according  to  the  aggregate
liquidation  amount of the Securities held by the relevant Holder in relation to
the  aggregate  liquidation  amount of all  Securities  outstanding  unless,  in
relation to a payment,  an Event of Default has occurred and is  continuing,  in
which case any funds  available to make such payment shall be paid first to each
Holder  of  the  Preferred  Securities  pro  rata  according  to  the  aggregate
liquidation amount of Preferred  Securities held by the relevant Holder relative
to the aggregate liquidation amount of all Preferred Securities outstanding, and
only after  satisfaction  of all amounts  owed to the  Holders of the  Preferred
Securities,  to each  Holder  of Common  Securities  pro rata  according  to the
aggregate  liquidation  amount of Common  Securities held by the relevant Holder
relative  to  the  aggregate   liquidation   amount  of  all  Common  Securities
outstanding.

         8. RANKING.  The Common  Securities rank pari passu and payment thereon
will be made Pro Rata with the Preferred  Securities  except that where an Event
of Default occurs and is continuing,  the rights of Holders of Common Securities
to payment in respect of Distributions and payments upon liquidation, redemption
or  otherwise  are  subordinate  to the  rights  of  Holders  of  the  Preferred
Securities.

         9.  MERGERS,  CONSOLIDATIONS  OR  AMALGAMATIONS.   The  Trust  may  not
consolidate,  amalgamate,  merge  with or into,  or be  replaced  by, or convey,
transfer or lease its properties and assets to, any corporation or other body.

         10. TRANSFERS,  EXCHANGES, METHOD OF PAYMENTS. Payment of Distributions
and  payments  on  redemption  of the Common  Securities  will be  payable,  the
transfer of the Common  Securities  will be registrable,  and Common  Securities
will be  exchangeable  for Common  Securities of other  denominations  of a like
aggregate  liquidation  amount,  at the principal  corporate trust office of the
Property Trustee in The City of New York; provided that payment of Distributions
may be made at the  option  of the  Regular  Trustees  on behalf of the Trust by
check mailed to the address of the persons entitled thereto and that the payment
on  redemption of any Common  Security will be made only upon  surrender of such
Common  Security  to  the  Property  Trustee.   Notwithstanding  the  foregoing,
transfers of Common  Securities  are subject to conditions  set forth in Section
9.01(c) of the Declaration.

         11. ACCEPTANCE OF INDENTURE.  Each Holder of Common Securities,  by the
acceptance  thereof,   agrees  to  the  provisions  of  the  Indenture  and  the
Debentures, including the subordination provisions thereof.

         12. NO PREEMPTIVE  RIGHTS.  The Holders of Common Securities shall have
no  preemptive  rights to  subscribe  to any  additional  Common  Securities  or
Preferred Securities.

         13.  MISCELLANEOUS.   These  terms  shall  constitute  a  part  of  the
Declaration.  The Trust will provide a copy of the Declaration and the Indenture
to a Holder  without  charge on written  request  to the Trust at its  principal
place of business.

                          [FORM OF REVERSE OF SECURITY]

         Distributions  payable on each Common  Security will be fixed at a rate
per annum of $2.75 per Common  Security,  such rate  being the rate of  interest
payable on the Debentures to be held by the Property  Trustee.  Distributions in
arrears for more than one  quarter  will bear  interest  thereon at the rate per
annum of 5.50% thereof (to the extent permitted by law) compounded monthly.  The
term  "Distributions"  as used herein means such cash distributions and any such
interest payable unless otherwise  stated. A Distribution is payable only to the
extent that payments are made in respect of the Debentures  held by the Property
Trustee. The amount of Distributions  payable for any period will be computed on
the basis of a 360-day year of twelve 30-day months.

         Except  as  otherwise  described  below,  distributions  on the  Common
Securities  will be  cumulative,  will accrue from  October 29, 1997 and will be
payable  quarterly in arrears,  on the last day of each  quarter,  commencing on
December 31, 1997, but only if and to the extent that interest payments are made
in respect of the Debentures held by the Property Trustee.  So long as AES shall
not be in default in the  payment of  interest  on the  Debentures,  AES has the
right under the  Indenture for the  Debentures to defer  payments of interest by
extending the interest  payment period from time to time on the Debentures for a
period not exceeding 20 consecutive  quarters (each an "Extension  Period") and,
as a consequence,  quarterly Distributions will continue to accrue with interest
thereon (to the extent  permitted  by  applicable  law) at the rate of 5.50% per
annum,  compounded  quarterly  during such  Extension  period;  provided that no
Extension  Period shall last beyond the date of maturity or any redemption  date
of the Debentures.  Prior to the termination of any such Extension  Period,  AES
may  commence  a new  Extension  Period;  provided  that such  Extension  Period
together with all such previous and further extensions thereof may not exceed 20
consecutive  quarterly interest periods.  Payments of accrued Distributions will
be payable to  Holders as they  appear on the books and  records of the Trust on
the  first  record  date  after  the  end  of the  Extension  Period.  Upon  the
termination of any Extension Period and the payment of all amounts then due, AES
may commence a new Extension Period, subject to the above requirements.

         The  Common   Securities   shall  be  redeemable  as  provided  in  the
Declaration.

         The Common Securities shall be convertible into shares of Common Stock,
through (i) the exchange of Common  Securities  for a portion of the  Debentures
and (ii) the immediate  conversion of such  Debentures into Common Stock, in the
manner and according to the terms set forth in the Declaration.

which the Guarantee  Trustee shall have received written notice or a Responsible
Officer charged with the  administration of this Guarantee  Agreement shall have
obtained written notice.

         (e) The Guarantee Trustee shall continue to serve as a Trustee unless a
Successor  Guarantee Trustee has been appointed and accepted that appointment in
accordance with Article 4.

         SECTION 3.02. Certain Rights and Duties of the Guarantee  Trustee.  (a)
The Guarantee  Trustee,  before the  occurrence of an Event of Default and after
the curing of all Events of Default that may have occurred,  shall  undertake to
perform  only  such  duties  as are  specifically  set  forth in this  Guarantee
Agreement,  and no implied covenants shall be read into this Guarantee Agreement
against the Guarantee  Trustee.  In case an Event of Default has occurred  (that
has not been cured or waived pursuant to Section 2.06(a)), the Guarantee Trustee
shall  exercise  such of the rights and  powers  vested in it by this  Guarantee
Agreement,  and use the same  degree of care and skill in their  exercise,  as a
prudent person would exercise or use under the  circumstances  in the conduct of
his or her own affairs.

          (b) No provision  of this  Guarantee  Agreement  shall be construed to
relieve the Guarantee Trustee from liability for its own negligent  action,  its
own negligent failure to act or its own willful misconduct, except that:




                                       8

         (i) prior to the occurrence of an Event of Default and after the curing
         or waiving of all such Events of Default that may have occurred:

                  (A) the duties and obligations of the Guarantee  Trustee shall
                  be  determined  solely  by  the  express  provisions  of  this
                  Guarantee  Agreement,  and the Guarantee  Trustee shall not be
                  liable  except  for  the   performance   of  such  duties  and
                  obligations  as are  specifically  set forth in this Guarantee
                  Agreement,  and no implied  covenants or obligations  shall be
                  read into  this  Guarantee  Agreement  against  the  Guarantee
                  Trustee; and

                  (B) in the  absence of bad faith on the part of the  Guarantee
                  Trustee,  the Guarantee  Trustee may conclusively  rely, as to
                  the  truth  of  the  statements  and  the  correctness  of the
                  opinions expressed therein,  upon any certificates or opinions
                  furnished  to the  Guarantee  Trustee  and  conforming  to the
                  requirements of this Guarantee  Agreement;  but in the case of
                  any such certificates or opinions that by any provision hereof
                  are  specifically  required to be furnished  to the  Guarantee
                  Trustee,  the  Guarantee  Trustee  shall  be  under  a duty to
                  examine the same to  determine  whether or not they conform to
                  the requirements of this Guarantee Agreement;

         (ii)  the  Guarantee  Trustee  shall  not be  liable  for any  error of
         judgment made in good faith by a  Responsible  Officer of the Guarantee
         Trustee,  unless  it shall be proved  that the  Guarantee  Trustee  was
         negligent in ascertaining the pertinent facts;

         (iii) the  Guarantee  Trustee  shall not be liable with  respect to any
         action  taken or omitted to be taken by it in good faith in  accordance
         with the  direction of the Holders of Preferred  Securities as provided
         herein  relating  to the  time,  method  and  place of  conducting  any
         proceeding  for any  remedy  available  to the  Guarantee  Trustee,  or
         exercising  any trust or power  conferred  upon the  Guarantee  Trustee
         under this Guarantee Agreement; and

         (iv) no  provision  of  this  Guarantee  Agreement  shall  require  the
         Guarantee  Trustee to  expend or risk its own funds or otherwise  incur
         personal  financial  liability in the performance of any of  its duties
         or in the  exercise  of any of its rights or powers,  if it shall  have
         reasonable  ground for  believing  that the repayment of such funds  or
         liability  is not  reasonably  assured  to it under  the terms of  this
         Guarantee  Agreement  or  adequate  indemnity  against  such  risk   or
         liability is not reasonably assured to it.

         (c) Subject to the provisions of Section 3.02(a) and (b):

         (i) whenever in the  administration  of this Guarantee  Agreement,  the
         Guarantee  Trustee  shall deem it desirable  that a matter be proved or
         established   prior  to  taking,   suffering  or  omitting  any  action
         hereunder,  the  Guarantee  Trustee  (unless  other  evidence is herein
         specifically  prescribed) may, in the absence of bad faith on its part,
         request  and rely  upon a  certificate,  which  shall  comply  with the
         provisions  of ss.  314(e) of the Trust  Indenture  Act,  signed by any
         authorized officer of the Guarantor;

         (ii) the Guarantee  Trustee (A) may consult with counsel  (which may be
         counsel to the Guarantor or any of its  Affiliates  and may include any
         of its  employees)  selected  by it in good faith and with due care and
         the written  advice or opinion of such  counsel  with  respect to legal
         matters  shall be full and complete  authorization  and  protection  in
         respect of any action  taken,  suffered or omitted by it  hereunder  in
         good faith and in reliance  thereon and in accordance  with such advice
         and  opinion  and  (B)  shall  have  the  right  at any  time  to  seek
         instructions  concerning the administration of this Guarantee Agreement
         from any court of competent jurisdiction;

         (iii) the  Guarantee  Trustee  may  execute any of the trusts or powers
         hereunder  or perform  any duties  hereunder  either  directly or by or
         through  agents or attorneys  and the  Guarantee  Trustee  shall not be
         responsible  for any  misconduct or negligence on the part of any agent
         or attorney appointed by it in good faith and with due care;

         (iv) the  Guarantee  Trustee  shall be under no obligation to  exercise
         any of the rights or powers vested in it by this  Guarantee   Agreement
         at the request or direction  of any Holders of  Preferred   Securities,
         unless  such  Holders  shall  have  offered to the  Guarantee   Trustee
         reasonable   security  and  indemnity  against  the  costs,    expenses
         (including  its  attorneys'  fees and expenses) and  liabilities   that
         might be incurred by it in complying  with such request  or  direction;
         provided that nothing  contained in this clause (iv) shall  relieve the
         Guarantee  Trustee of the obligation,  upon the occurrence of  an Event
         of Default  (which has not been cured or waived) to  exercise  such  of
         the rights and powers vested in it by this Guarantee Agreement, and  to
         use the same degree of care and skill in this  exercise,  as a  prudent
         person would exercise or use under the circumstances in the conduct  of
         his or her own affairs; and

         (v) any action taken by the Guarantee  Trustee or its agents  hereunder
         shall bind the Holders of the Preferred Securities and the signature of
         the  Guarantee  Trustee or its agents  alone  shall be  sufficient  and
         effective  to 


                                       10
<PAGE>


         perform  any such  action;  and no third  party  shall be  required  to
         inquire as to the authority of the Guarantee  Trustee to so act, or  as
         to its  compliance  with  any of the  terms  and  provisions  of   this
         Guarantee Agreement,  both of which shall be conclusively evidenced  by
         the Guarantee Trustee's or its agent's taking such action.

         SECTION 3.03.  Not  Responsible  for Recitals or Issuance of Guarantee.
The recitals contained in this Guarantee shall be taken as the statements of the
Guarantor and the Guarantee Trustee does not assume any responsibility for their
correctness.  The Guarantee Trustee makes no  representations as to the validity
or sufficiency of this Guarantee Agreement.

                                GUARANTEE TRUSTEE

         SECTION  4.01.  Qualifications.  (a)  There  shall  at all  times  be a
Guarantee Trustee which shall:

         (i)      not be an Affiliate of the Guarantor; and

         (ii)     be a national banking association or corporation organized and
                  doing  business under the laws of the United States of America
                  or any  State  or  Territory  thereof  or of the  District  of
                  Columbia,   or  a  corporation  or  Person  permitted  by  the
                  Commission to act as an institutional  trustee under the Trust
                  Indenture  Act,   authorized   under  such  laws  to  exercise
                  corporate trust powers,  having a combined capital and surplus
                  of  at  least  $50,000,000,  and  subject  to  supervision  or
                  examination  by  Federal,  State,  Territorial  or District of
                  Columbia authority.  If such corporation  publishes reports of
                  condition  at  least  annually,  pursuant  to  law  or to  the
                  requirements  of  the   supervising  or  examining   authority
                  referred  to  above,  then for the  purposes  of this  section
                  4.01(a)(ii),   the  combined   capital  and  surplus  of  such
                  corporation  shall be deemed to be its  combined  capital  and
                  surplus as set forth in its most recent report of condition so
                  published.

         If at any  time the  Guarantee  Trustee  shall  cease  to  satisfy  the
requirements of clauses (i)-(ii) above, the Guarantee  Trustee shall immediately
resign  in the  manner  and with the  effect  set out in  Section  4.02.  If the
Guarantee  Trustee has or shall acquire any  "conflicting  interest"  within the
meaning of ss. 310(b) of the Trust

Indenture  Act, the Guarantee  Trustee and the  Guarantor  shall in all respects
comply with the provisions of ss. 310(b) of the Trust Indenture Act.

         SECTION  4.02.  Appointment,   Removal  and  Resignation  of  Guarantee
Trustee.  (a) Subject to Section 4.02(b), the Guarantee Trustee may be appointed
or removed  without  cause at any time by the  Guarantor  except  following  the
occurrence and during the continuation of an Event of Default.

          (b) The  Guarantee  Trustee  shall not be removed in  accordance  with
Section   4.02(a)   until  a  Successor   Guarantee   Trustee   possessing   the
qualifications  to act as  Guarantee  Trustee  under  Section  4.01(a)  has been
appointed and has accepted such  appointment by written  instrument  executed by
such  Successor  Guarantee  Trustee  and  delivered  to the  Guarantor  and  the
Guarantee Trustee being removed.

          (c) The Guarantee  Trustee appointed to office shall hold office until
his successor shall have been appointed or until its removal or resignation.

          (d) The  Guarantee  Trustee may resign from office  (without  need for
prior or subsequent  accounting) by an instrument (a  "Resignation  Request") in
writing signed by the Guarantee  Trustee and delivered to the  Guarantor,  which
resignation  shall take effect upon such  delivery or upon such later date as is
specified therein; provided,  however, that no such resignation of the Guarantee
Trustee shall be effective until a Successor  Guarantee  Trustee  possessing the
qualifications  to act as  Guarantee  Trustee  under  Section  4.01(a)  has been
appointed  and has accepted  such  appointment  by  instrument  executed by such
Successor  Guarantee  Trustee  and  delivered  to  Guarantor  and the  resigning
Guarantee Trustee.

          (e) If no Successor  Guarantee  Trustee shall have been  appointed and
accepted  appointment as provided in this Section 4.02 delivery to the Guarantor
of a Resignation Request, the resigning Guarantee Trustee may petition any court
of competent jurisdiction for appointment of a Successor Guarantee Trustee. Such
court may  thereupon  after  such  notice,  if any,  as it may deem  proper  and
prescribe, appoint a Successor Guarantee Trustee.

                                    GUARANTEE

         SECTION 5.01. Guarantee.  The Guarantor irrevocably and unconditionally
agrees to pay in full to the Holders the Guarantee Payments (without duplication
of amounts  theretofore paid by the Issuer) regardless of any defense,  right of
set-off or  counterclaim  which the Issuer may have or assert.  The  Guarantor's
obligation to make a Guarantee Payment may be satisfied by direct payment of the
required amounts by the Guarantor to the Holders or by causing the Issuer to pay
such amounts to the Holders.

         SECTION 5.02.  Waiver of Notice.  The Guarantor hereby waives notice of
acceptance of this Guarantee  Agreement and of any liability to which it applies
or may apply, presentment, demand for payment, any right to require a proceeding
first  against  the Issuer or any other  Person  before  proceeding  against the
Guarantor,  protest,  notice  of  nonpayment,  notice  of  dishonor,  notice  of
redemption and all other notices and demands.

         SECTION 5.03.  Obligations Not Affected.  The  obligations,  covenants,
agreements and duties of the Guarantor  under this Guarantee  Agreement shall in
no way be affected or impaired by reason of the  happening  from time to time of
any of the following:

              (a) the release or waiver,  by operation of law or  otherwise,  of
         the  performance  or observance by the Issuer of any express or implied
         agreement,  covenant,  term  or  condition  relating  to the  Preferred
         Securities to be performed or observed by the Issuer;

              (b) the  extension of time for the payment by the Issuer of all or
         any portion of the  Distributions  (other than an extension of time for
         payment  of  Distributions  that  results  from  the  extension  of any
         interest   payment  period  on  the  Debentures),   Redemption   Price,
         Liquidation  Distribution  (as defined in the Declaration) or any other
         sums  payable  under  the  terms  of the  Preferred  Securities  or the
         extension of time for the  performance of any other  obligation  under,
         arising out of, or in connection with, the Preferred Securities;

              (c) any failure,  omission, delay or lack of diligence on the part
         of the Holders to enforce,  assert or  exercise  any right,  privilege,
         power or remedy  conferred on the Holders  pursuant to the terms of the
         Preferred Securities,  or any action on the part of the Issuer granting
         indulgence or extension of any kind;



                                       13
<PAGE>


              (d) the voluntary or involuntary liquidation, dissolution, sale of
         any collateral,  receivership,  insolvency,  bankruptcy, assignment for
         the benefit of creditors,  reorganization,  arrangement, composition or
         readjustment of debt of, or other similar  proceedings  affecting,  the
         Issuer or any of the assets of the Issuer;

              (e) any  invalidity  of, or defect or deficiency in, the Preferred
         Securities;

              (f) the  settlement  or compromise  of any  obligation  guaranteed
         hereby or hereby incurred; or

              (g)  any  other  circumstance   whatsoever  that  might  otherwise
         constitute a legal or equitable discharge or defense of a guarantor, it
         being the  intent of this  Section  5.03  that the  obligations  of the
         Guarantor  hereunder shall be absolute and unconditional  under any and
         all circumstances.

         There  shall be no  obligation  of the  Holders  to give  notice to, or
obtain  consent of, the  Guarantor  with respect to the  happening of any of the
foregoing.

         SECTION 5.04. Enforcement of Guarantee. The Guarantor and the Guarantee
Trustee  expressly  acknowledge  that  (i)  this  Guarantee  Agreement  will  be
deposited with the Guarantee  Trustee to be held for the benefit of the Holders;
(ii) the Guarantee Trustee has the right to enforce this Guarantee  Agreement on
behalf of the Holders;  (iii) Holders  representing  not less than a Majority in
liquidation  amount of the  Preferred  Securities  have the right to direct  the
time,  method and place of conducting any proceeding for any remedy available in
respect of this  Guarantee  Agreement  including the giving of directions to the
Guarantee  Trustee,  or exercising  any trust or other power  conferred upon the
Guarantee Trustee under this Guarantee  Agreement,  and (iv) notwithstanding the
foregoing,  if the Guarantor has failed to make any Guarantee Payment hereunder,
any Holder of Preferred  Securities  may institute a legal  proceeding  directly
against the  Guarantor  to enforce its rights  under this  Guarantee  Agreement,
without first instituting a legal proceeding  against the Issuer,  the Guarantee
Trustee, or any other Person.

         SECTION 5.05. Guarantee of Payment.  This Guarantee Agreement creates a
guarantee of payment and not merely of collection. This Guarantee Agreement will
not be discharged  except by payment of the Guarantee  Payments in full (without
duplication of amounts theretofore paid by the Issuer).



                                       14
<PAGE>


         SECTION 5.06. Subrogation. The Guarantor shall be subrogated to all (if
any) rights of the Holders  against the Issuer in respect of any amounts paid to
the Holders by the Guarantor under this Guarantee Agreement;  provided, however,
that the  Guarantor  shall not  (except  to the  extent  required  by  mandatory
provisions  of law) be entitled to enforce or exercise  any rights  which it may
acquire  by  way  of  subrogation  or  any  indemnity,  reimbursement  or  other
agreement,  in all cases as a result of payment under this Guarantee  Agreement,
if, at the time of any such  payment,  any amounts are due and unpaid under this
Guarantee  Agreement.  If any amount shall be paid to the Guarantor in violation
of the preceding sentence, the Guarantor agrees to hold such amount in trust for
the Holders and to pay over such amount to the Holders.

         SECTION 5.07. Independent Obligations.  The Guarantor acknowledges that
its obligations  hereunder are independent of the obligations of the Issuer with
respect to the Preferred  Securities  and that the Guarantor  shall be liable as
principal and as debtor  hereunder to make  Guarantee  Payments  pursuant to the
terms of this Guarantee  Agreement  notwithstanding  the occurrence of any event
referred to in subsections (a) through (g), inclusive, of Section 5.03 hereof.


                                    ARTICLE 6
                    LIMITATION OF TRANSACTIONS; SUBORDINATION

         SECTION  6.01.  Limitation  of  Transactions.  So long as any Preferred
Securities remain  outstanding,  the Guarantor will not declare or pay dividends
on, or redeem,  purchase,  acquire or make a distribution or liquidation payment
with  respect  to,  any of its  common  stock  or  preferred  stock  or make any
guarantee payment with respect thereto or make any payment of interest,  premium
(if any) or principal on any debt securities  issued by the Guarantor which rank
pari passu with or junior to the  Debentures,  if at such time (i) the Guarantor
shall be in default  with  respect to its  Guarantee  Payments or other  payment
obligations hereunder, (ii) there shall have occurred any event of default under
the  Declaration or (iii) the Guarantor shall have given notice of its selection
of an Extension  Period (as defined in the  Indenture)  and such period,  or any
extension thereof, is continuing;  provided that the foregoing will not apply to
any stock dividends paid by the Guarantor in Common Stock. In addition,  so long
as any Preferred  Securities remain  outstanding,  the Guarantor (i) will remain
the sole direct or indirect owner of all of the  outstanding  Common  Securities
and shall not cause or permit the Common Securities to be transferred  except to
the extent such  transfer is permitted  under  Section 9.01 of the  Declaration;
provided that any permitted  successor of the Guarantor  under the Indenture may
succeed to the Guarantor's  ownership of the Common Securities and (ii) will use
reasonable efforts to cause




                                       15
<PAGE>

the  Issuer to  continue  to be treated  as a grantor  trust for  United  States
federal  income  tax  purposes  except  in  connection  with a  distribution  of
Debentures as provided in the Declaration.

         SECTION 6.02.  Subordination.  This Guarantee Agreement will constitute
an unsecured  obligation  of the  Guarantor  and will rank (i)  subordinate  and
junior in right of payment to all other liabilities of the Guarantor,  including
the Debentures,  except those made pari passu herewith or subordinate  hereto by
their  terms,  and (ii)  pari  passu in right of  payment  with the most  senior
preferred  stock  issued,  from time to time,  if any, by the Guarantor and with
respect to obligations under other guarantee  agreements which the Guarantor may
enter into from time to time to the extent that such agreements shall be entered
into in substantially  the form hereof and provide for comparable  guarantees by
the Guarantor of payment on preferred securities issued by other AES Trusts.


                                    ARTICLE 7
                                   TERMINATION

         SECTION 7.01. Termination. This Guarantee Agreement shall terminate and
be of no further force and effect upon full payment of the  Redemption  Price of
all Preferred  Securities,  or upon the distribution of Debentures to Holders of
Preferred  Securities and Common Securities in exchange for all of the Preferred
Securities and Common Securities, or upon full payment of the amounts payable in
accordance with the Declaration upon liquidation of the Issuer.  Notwithstanding
the foregoing, this Guarantee Agreement will continue to be effective or will be
reinstated,  as the case may be, if at any time any Holder must restore  payment
of any sums paid with  respect to the  Preferred  Securities  or this  Guarantee
Agreement.


                                    ARTICLE 8
                    LIMITATION OF LIABILITY; INDEMNIFICATION

         SECTION 8.01.  Exculpation.  (a) No Indemnified Person shall be liable,
responsible  or  accountable  in damages or  otherwise  to the  Guarantor or any
Covered  Person for any loss,  damage or claim  incurred by reason of any act or
omission  performed or omitted by such Indemnified Person in good faith and in a
manner such Indemnified Person reasonably believed to be within the scope of the
authority conferred on such Indemnified Person by this Guarantee Agreement or by
law, except that an Indemnified Person shall be liable for any such loss, damage
or claim incurred by reason of such Indemnified  Person's  negligence or willful
misconduct with respect to such acts or omissions.



                                       16
<PAGE>


         (b) An Indemnified  Person shall be fully  protected in relying in good
faith upon the records of the  Guarantor  and upon such  information,  opinions,
reports or statements presented to the Guarantor by any Person as to matters the
Indemnified   Person   reasonably   believes  are  within  such  other  Person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Guarantor,  including information,  opinions,  reports or
statements  as to the value  and  amount of the  assets,  liabilities,  profits,
losses,  or any other facts pertinent to the existence and amount of assets from
which Distributions to Holders of Preferred Securities might properly be paid.
